Glossary

Twenty terms a quant desk would assume you know. Each definition is short and linked to the Closelook framework that uses it — so a glossary entry doubles as a map into the rest of the site.

3

3D Stacking: Vertical integration of chips into a stack rather than side by side; high-bandwidth memory (HBM) is the consumer example.

A

ABR (Agent Beneficiary Ratio): Closelook's 5-dimension scoring framework rating how much a public company benefits from or is threatened by AI agent disruption.
ACV (Annual Contract Value): The annualized revenue from a single customer contract; differentiate from company-wide ARR and from lifetime value (LTV).
Advanced Packaging: Umbrella term for techniques like CoWoS, chiplets, and 3D stacking that integrate multiple dies into one package; a primary AI supply constraint.
AI Barbell: Closelook's portfolio construction pairing long AI-infrastructure exposure against short disrupted-SaaS exposure.
Alpha: Return above a benchmark. In prediction markets context, Closelook's Directional Alpha framework identifies 51 patterns for generating returns above the market's implied probability.
ARR (Annual Recurring Revenue): The annualized value of a SaaS company's recurring subscription revenue; the foundation of SaaS valuation and the metric agentic disruption pressures.
ARR Multiple: Enterprise value divided by ARR; SaaS valuation shorthand that compressed from 30x+ in 2021 to roughly 8-15x by 2024-26.
ASIC (Application-Specific Integrated Circuit): A chip designed for one specific workload rather than general-purpose computing; the hyperscaler answer to NVIDIA GPU dependence.
Assignment: When an option seller is required to fulfill the contract because the buyer exercises; the event that converts a short option into a stock position.
ATE (Automated Test Equipment): Machines that test semiconductor chips before shipping. Advantest dominates ATE for advanced logic and HBM. Testing is an underappreciated bottleneck — every chip must pass ATE before it generates revenue.
ATM (At-The-Money): An option whose strike price is approximately equal to the current price of the underlying; carries the highest gamma and the most time premium per day.
AW25 (Agentic Winners 25): A tactical 25-name sensor array of agentic-software companies spanning 7 sectors, tracking the agentic transition in real time.

B

Backside Power Delivery: A chip architecture moving power routing to the underside of the wafer, freeing the front for signal wiring; a key node-transition technology.
Bandwidth (Memory / Networking): The rate at which data can be transferred; the constraint that binds AI performance after raw compute is satisfied.
Base Rate: The historical frequency of an event class; the calibration anchor any forecast should start from before adjusting for specifics.
Basis Risk: The risk that a hedge and the position it protects do not move together perfectly; relevant for any cross-asset hedge.
Beta: The sensitivity of an asset's returns to overall market movements; a beta of 1 moves with the market, the companion concept to alpha.
Bid-Ask Spread: The gap between the highest buy price and the lowest sell price; the primary execution cost in any market.
Binary Option (Prediction Market Context): A contract paying a fixed amount ($1) if an event occurs and nothing if it does not; the structural form of all prediction-market contracts.
Bollinger Coiling: A Closelook-tracked state where Bollinger Bands compress tightly, signaling a coming volatility expansion.
Bookings vs Revenue: Bookings are contracted future revenue; revenue is what is recognized now. Bookings lead, revenue lags.
Brier Score: Accuracy score for probabilistic forecasts — mean squared difference between predicted probability and actual outcome. Lower is better; perfect = 0, worst = 1. Closelook scores every Predictions call with Brier alongside log-loss so the public scoreboard rewards calibration, not confident wrongness.
Burn Rate: The rate at which a company consumes cash each month; paired with runway, it is the survival math for unprofitable SaaS.

C

CAC (Customer Acquisition Cost): The total sales and marketing cost to acquire one new customer; the denominator in the LTV/CAC efficiency ratio.
CAC Payback Period: The number of months for a customer's gross profit to recover their acquisition cost; under 12 months is excellent, over 24 is problematic.
Calibration (Forecasting): The alignment between stated probabilities and actual outcome frequencies; a calibrated 70% forecaster is right 70% of the time on 70% calls.
Call Option: A contract giving the buyer the right, not the obligation, to buy the underlying at a fixed strike price before expiry; buyers gain leveraged upside, sellers collect premium.
CapEx Cycle: The pattern of capital expenditure growth and contraction in an industry. AI infrastructure is in the expansion phase. Historical parallels (2000 Telecom, 2018 Crypto) suggest CapEx cycles end suddenly.
Carry Trade: Borrowing in a low-yield currency to invest in a higher-yield one; the engine behind JPY-funding flows that affect tech valuations.
Cascade Tracker (5-Domino Cascade): Closelook's 5-step sequence model for how a regime breakdown propagates across cross-asset relationships.
Cash-Secured Put: An options strategy: sell a put option while holding enough cash to buy the stock if assigned. Used by Closelook to enter positions at lower prices while earning premium. The Derivatives portfolio is 80-95% cash with puts generating income.
CFTC (US Commodity Futures Trading Commission): The US regulator of derivatives and event contracts; its oversight is what makes Kalshi a legal domestic prediction market.
Charm (Delta Decay): A second-order Greek measuring how an option's delta changes simply with the passage of time — most pronounced for short-dated options near expiry.
Chiplet: A modular chip design connecting multiple smaller dies in one package; lowers yield risk at the cost of integration complexity.
Churn: The customers or revenue lost in a period; logo churn counts customers, revenue churn counts dollars, and they diverge meaningfully.
Cluster (GPU/AI): A networked group of GPUs working in parallel for training or inference; scale exposes bandwidth as the binding constraint.
Cohort Analysis: Tracking groups of customers by acquisition period to reveal retention and expansion dynamics invisible in aggregate metrics.
Cointegration: A statistical property where two assets share a long-run equilibrium; the foundation of Closelook's pair-trade methodology.
Collar: A defined-range options position combining long stock, a long protective put, and a short covered call to cap both downside and upside.
Compute (AI): The general term for processing capacity used to train or run AI models; measured in FLOPS, TOPS, or GPU-hours.
Constraint Sector: Segments of the AI supply chain where structural demand exceeds supply, giving suppliers durable pricing power.
Convexity: The rate of change of a bond's duration; it makes price gains from falling rates exceed price losses from rising rates.
Correlation: A statistical measure of how two assets move together, from -1 to +1; the foundation of cross-asset and pair-trade analysis.
Covered Call: An options strategy: own the underlying stock and sell a call option against it. Generates income but caps upside. Used extensively in Closelook's Derivatives portfolio for income generation in sideways markets.
CoWoS (Chip-on-Wafer-on-Substrate): TSMC's advanced packaging technology that bonds compute dies with HBM memory stacks. The primary packaging bottleneck in the AI supply chain. Capacity sold out since 2023.
CPI (Consumer Price Index): The standard measure of consumer inflation; a market-moving monthly release that shapes Fed rate expectations.
CPU (Central Processing Unit): A general-purpose processor optimized for sequential tasks; contrasts with the GPU's parallel architecture for AI workloads.
Credit Spread: The yield difference between corporate bonds and Treasuries; a primary stress gauge for risk assets.
Curve Inversion: When short-term yields exceed long-term yields; a recession indicator that historically leads downturns by 12-18 months.

D

Daily Pulse: Closelook's daily market read covering temperature, cross-asset moves, regional action, and basket performance.
Data Center (AI Data Center): A facility housing servers and accelerators; AI-optimized data centers differ from traditional ones in power and cooling density.
Delta: The options Greek measuring directional exposure; ranges -1 to 1, and roughly approximates the probability of finishing in-the-money.
Diagonal Spread: An options spread using different strikes AND different expiries; typically a longer-dated long leg against a shorter-dated short leg.
Die: A single piece of silicon containing a chip's circuitry, cut from a larger wafer; the unit yield is measured against.
Directional Alpha: Closelook's systematic framework of 51 patterns for trading prediction markets.
Divergence (Technical): A disagreement between price and a confirming indicator such as RSI or MACD, flagging a potential trend exhaustion.
DRAM: Dynamic random-access memory; the volatile main-memory technology and the base from which high-bandwidth memory (HBM) is built.
Duration: A bond's price sensitivity to interest-rate changes; longer duration means larger price swings per unit of rate move.
DWDM (Dense Wavelength Division Multiplexing): An optical networking technique sending many wavelengths of light down one fiber, multiplying interconnect capacity for AI clusters.
DXY (US Dollar Index): An index measuring the US dollar against a basket of six major currencies. DXY strength is typically a headwind for non-US tech stocks and commodities including Bitcoin. The Weekly Signal tracks DXY through the Macro dimension.

E

EBITDA Multiple: Enterprise Value divided by EBITDA — the most common valuation metric for comparing companies across sectors. In the context of the Software-Credit Nexus, PE-acquired SaaS companies are leveraged at 8-10x EBITDA, creating risk when margins compress.
Economic Moat: A durable competitive advantage that protects profits. In AI investing, Closelook distinguishes between physics-based moats (ASML's EUV monopoly, TSMC's fabrication lead) and software moats (which agentic AI may erode).
EDA (Electronic Design Automation): Software used to design and verify chips; a near-duopoly of Cadence and Synopsys sitting upstream of every modern semiconductor.
Elliott Wave Theory: A technical analysis framework that identifies recurring fractal wave patterns in price action. Markets move in five-wave impulse sequences (trending) and three-wave corrective sequences (counter-trend). Closelook applies Elliott Wave analysis to BTC and NDX as a qualitative overlay on the Weekly Signal framework.
Ethernet (AI Networking): The standard networking protocol now challenging InfiniBand in AI clusters via the Broadcom-led Ultra Ethernet initiative.
Euro-AI 50: Closelook's European AI-sovereignty index of 45-55 names trading at a deep discount to US peers.
EUV (Extreme Ultraviolet Lithography): The most advanced chipmaking technology using 13.5nm wavelength light. ASML is the sole supplier of EUV machines. Required for all advanced chips below 7nm. ASML's EUV order book is a Closelook Sentinel indicator.
EV/Revenue: Enterprise value divided by revenue; the default valuation metric for high-growth SaaS when EBITDA is negative.
Event Contract: A financial contract that resolves on the outcome of a real-world event; the regulated framing of a prediction-market contract.
Exercise: When an option holder invokes the right to buy (call) or sell (put) the underlying at the strike price.
Expansion Revenue: Revenue growth from existing customers via upsell, cross-sell, and increased usage; the engine behind net revenue retention above 100%.
Expiration: The fixed date on which an option contract resolves; available as weekly, monthly, or long-dated LEAPS expiries.

F

Fab (Fabrication Facility): A semiconductor manufacturing plant; leading-edge fabs cost $15-25B+ to build, concentrating production among a few players.
FCF (Free Cash Flow): Cash generated after operating expenses and capex; the number that survives the hype cycle and grounds mature-SaaS valuation.
Fed Funds Rate: The US central bank's overnight policy rate; the anchor for all dollar-denominated financial conditions.
Flash Memory (NAND Flash): Non-volatile storage that retains data without power; the technology underlying SSDs and the AI data-storage layer.
FPGA (Field-Programmable Gate Array): A reconfigurable chip whose logic can be rewritten after manufacture; occupies a niche AI role between GPUs and fixed ASICs.
Functional Index: A proprietary Closelook concept: indices weighted by supply chain function rather than market capitalization. Reveals structural dynamics that cap-weighted ETFs (SMH, SOXX) miss.
Funding Rate (Crypto): The periodic payment mechanism on crypto perpetual futures that keeps them tethered to spot; a real-time sentiment gauge.

G

Gamma: The options Greek measuring the rate of change of delta; highest near at-the-money and near expiry, where short options become most dangerous.
Gamma Squeeze: A self-reinforcing rally in which heavy call buying forces short-gamma dealers to buy the underlying as it rises, and that hedging itself pushes price higher.
Generation Rotation: Closelook's sector-leadership rotation framework tied to NVIDIA's GPU generation phases: Dawn, Early Ramp, Mid, Sunset.
Golden Cross: Bullish trend-follow signal when the 50-day moving average crosses above the 200-day moving average. The Death Cross is the mirror image. Simple, widely watched, often self-fulfilling on index futures. The Pattern Engine logs Golden / Death Crosses across Rubin and Euro-AI as one of 51 Directional-Alpha patterns.
Gross Margin: Revenue minus cost of goods sold, divided by revenue. A simple quality gauge. SaaS compounders sit at 70-85%, semiconductor designers at 50-70%, commodity producers below 30%. Expanding gross margin usually signals pricing power; contracting margin is an early warning. HALO 100 screens compounders on sustained gross-margin levels.

H

HALO 100: Closelook's functional growth-compounder index of 100 names across 12 sectors.
HBM (High Bandwidth Memory): Vertically stacked DRAM dies connected to GPUs via advanced packaging. Essential for AI accelerators — HBM3E is current generation, HBM4 is next. Micron and SK Hynix control supply.
Heresy (Closelook Heresies): Closelook's editorial format for short-form opinions taken explicitly against prevailing market consensus.
High Yield / Investment Grade: The credit-quality split in corporate bonds; below BBB- is high yield (junk), at or above is investment grade.
Hurst Exponent: A statistical measure of time-series persistence on a 0-1 scale: below 0.5 is mean-reverting, above 0.5 is trending.

I

Immersion Cooling: A data-center cooling method that submerges hardware in non-conductive dielectric fluid; emerging for racks above 100kW.
Implied Volatility: The market's forward-looking volatility forecast, extracted from option prices. Not historical — expectational. High IV means rich option premium; low IV means cheap premium. Closelook's Derivatives portfolio sells premium when IV Rank is in the upper quartile and steps aside when it collapses.
InfiniBand: A high-bandwidth, low-latency networking protocol that NVIDIA controls via its Mellanox acquisition; the incumbent in AI clusters.
Information Ratio: Active return per unit of tracking error; the benchmark-relative cousin of the Sharpe Ratio, measuring consistency of outperformance.
Iron Condor: A defined-risk neutral options strategy combining a put credit spread and a call credit spread on the same underlying and expiry.
ITM (In-The-Money): An option that holds intrinsic value: a call with the stock above the strike, or a put with the stock below the strike.
IV Rank: Where current implied volatility sits within its trailing 52-week range, on a 0-100 scale; the timing signal for premium selling.

J

January Effect: Seasonal anomaly where small-cap equities historically outperform in January, driven by December tax-loss selling reversing plus start-of-year reinvestment flows. Documented since the 1970s, the effect has attenuated since 2000 as index futures and tax-aware strategies arbitraged it out. Noted in the Weekly Signal's seasonality layer but never a standalone Closelook thesis.

K

Kalshi: A US-regulated event-contract exchange operating under CFTC oversight; the leading onshore prediction market.
Kelly Criterion: A mathematical formula for optimal position sizing. It calculates the fraction of capital to allocate to a trade based on the probability of winning and the payoff ratio. Closelook uses a fractional Kelly approach (typically half-Kelly) to determine position sizes across the ten reference portfolios.

L

Lab Grid: Closelook's live grid scoring 60+ ETFs across Hurst, cointegration, and regime dimensions.
Latency (Hardware): The time delay in moving data between components; lower latency means higher cluster utilization at scale.
Linear Regression Channel: A statistical trend channel constructed by regressing price on time, then plotting upper and lower parallel bands at one or two standard deviations above and below the regression line. Used for mean-reversion entries inside a trend. Closelook's Cointegration Monitor leans on LRC deviations to timestamp pair-trading entries.
Liquid Cooling: Direct-to-chip or rack-level liquid cooling; now standard for AI data centers above roughly 50kW per rack.
Liquidity (Prediction Markets): The depth available at given prices; usually thin in tail contracts, which limits executable size and widens effective spreads.
Lithography: The chip-manufacturing step that uses light to pattern circuits onto silicon; ASML's EUV monopoly defines the leading edge.
Log Loss: A forecasting accuracy score that punishes confident wrong calls severely; a companion to the Brier Score that Closelook uses alongside it.
Logo Retention: The percentage of customers retained over a period, ignoring expansion; a cleaner signal of product stickiness than net revenue retention.
Long Gamma: A position whose hedge moves against the market — selling into strength and buying into weakness — which dampens volatility and stabilises price.
LTV (Lifetime Value): The total gross profit expected from a customer over the relationship's life; the foundation of SaaS unit economics.
LTV/CAC Ratio: Customer lifetime value divided by acquisition cost; above 3x is healthy, above 5x is excellent, below 1x destroys capital.

M

Magic Number: The ratio of new ARR to prior-period sales and marketing spend; above 0.75 indicates efficient, repeatable growth.
Market Breadth: How many stocks are participating in a market move — advance-decline line, new highs vs new lows, the share of stocks above the 200-day moving average. A narrow rally carried by a handful of mega-caps is structurally fragile; broad breadth confirms regime strength. Closelook feeds breadth into the Money Temperature composite.
Market Maker (Dealer): A liquidity provider that quotes both bid and offer and takes the other side of customer option trades, then hedges the resulting risk in the underlying.
Market Regime: The prevailing market environment that determines whether risk-taking is rewarded or punished. Closelook scores regime on a 0-100 composite: 80+ is Green (risk-on), 50-79 Yellow (caution), below 50 Red (risk-off). Regime determination is the first and most important level of the Weekly Signal.
Maximum Drawdown: The largest peak-to-trough decline in portfolio value. Closelook reports max drawdown for every portfolio and uses the Weekly Signal regime system to manage drawdown risk — Red regime triggers capital preservation.
Mean Reversion: The tendency of prices to return toward a historical average; the foundation of cointegration and pair-trade strategies, opposite to momentum.
Memory Bandwidth: The rate at which data moves between memory and the processor; the specific bottleneck that high-bandwidth memory (HBM) exists to relieve.
Metaculus: A forecasting community that aggregates members' probability estimates without monetary stakes; a calibration benchmark rather than a market.
Momentum: The tendency of a price trend to persist in its current direction; the foundation of trend-following, opposite to mean reversion.
Money Temperature: Closelook's 0-100 regime score across 8 instruments and 5 dimensions, classifying market regime intensity.
MOVE Index: The bond market's volatility index, derived from Treasury options; the fixed-income equivalent of the VIX.
MRR (Monthly Recurring Revenue): The monthly version of ARR; the standard recurring-revenue metric for early-stage and product-led SaaS.

N

Naked Option: A short option sold without owning the underlying or holding an offsetting position; carries undefined (potentially unlimited) risk.
Net New ARR: New ARR plus expansion ARR minus churned ARR; the single cleanest measure of recurring-revenue growth in a period.
Net Revenue Retention (NRR): Measures how much revenue existing customers generate year-over-year including expansion, contraction, and churn. NRR above 120% is exceptional (customers spend more). The SaaSpocalypse thesis predicts NRR compression as agents replace SaaS seats.
Networking Fabric: The interconnect architecture linking compute nodes; topologies include Spine-Leaf, Fat-Tree, and Dragonfly.
Node (Process Node): A semiconductor manufacturing generation labeled by feature size (3nm, 5nm, 7nm); smaller is denser but harder to manufacture.
NVMe (Non-Volatile Memory Express): A high-speed storage protocol built for flash; the standard for the data-pipeline layer feeding AI training.

O

OHLC: Open, High, Low, Close — the four price points that summarise a trading interval. OHLC bars and their cousin, the candlestick, are the foundation of price charts and almost every technical pattern. Closelook's Stock Detail page renders OHLC with a 50/200 SMA overlay using the LightweightCharts library.
Open Interest: The total number of outstanding option or event contracts not yet closed or settled; a liquidity and positioning indicator.
Operating Margin: Operating income divided by revenue; mature SaaS targets 25%+, and compression is an early agentic-disruption warning.
Optical Transceiver: A device converting electrical signals to optical for fiber networking; LITE, COHR, and FN are pure-play beneficiaries.
OTM (Out-of-The-Money): An option with no intrinsic value: a call with the stock below the strike, or a put with the stock above the strike.
Outcome-Based Pricing: Pricing tied to results delivered rather than seats or usage; the Work-as-a-Service monetization model for software that executes work.

P

Pattern 03 (NVIDIA Authority): Closelook's live cohort of Strategic Authority trades, reporting an XIRR of +109%.
Pattern Engine: Closelook's live signal feed applying Lab pattern methodology to current markets in real time.
PCIe (Peripheral Component Interconnect Express): The standard interface connecting GPUs and storage to servers; the PCIe 5.0 to 6.0 transition is underway.
PEG Ratio: Price / Earnings divided by earnings growth rate. PEG below 1 is the textbook growth-at-a-reasonable-price threshold; PEG above 2 signals the market is paying richly for growth assumptions that may not materialise. HALO 100 uses PEG bands as part of its compounder screen; Hypergrowth relaxes them in exchange for higher growth signal.
Photolithography: Light-based patterning of circuits onto silicon; the foundational step beneath all modern chip manufacturing.
Photonics (Silicon Photonics): Optical interconnects integrated directly with silicon; the foundation of co-packaged optics for next-generation AI systems.
Polymarket: A crypto-based prediction market with an offshore regulatory structure, settling in stablecoins rather than fiat.
Power Density: The electrical power consumed per rack; AI racks run 50-120kW versus 5-10kW for traditional racks.
PPI (Producer Price Index): A measure of wholesale-level inflation; it tends to lead consumer inflation (CPI) by feeding into final goods prices.
Premium (Options): The price paid by the option buyer and received by the seller for the contract; quoted per share, multiplied by 100 per contract.
Protective Put: A long put bought against a held stock position; portfolio insurance with a known, fixed cost.

Q

QE (Quantitative Easing): Central bank asset purchases that expand the balance sheet and inject liquidity; an expansionary, risk-asset-friendly regime.
QT (Quantitative Tightening): Central bank balance-sheet reduction that withdraws liquidity; a contractionary regime that pressures risk assets.
Quick Ratio: (Current assets minus inventory) divided by current liabilities. Measures short-term liquidity without assuming inventory can be sold quickly. Above 1.0 means a company can cover near-term obligations from liquid assets alone. Rubin 100 requires a Quick Ratio above 1.2 for cyclical semiconductor and memory constituents — margin of safety for capex-heavy names.

R

Rack (Server Rack): The physical unit housing servers in a data center; AI rack densities run 10-25x traditional power levels.
Real Yield: Nominal yield minus expected inflation; the cleaner asset-allocation signal than nominal rates alone.
Reference Portfolio: Closelook's eight live model portfolios run with real capital — skin-in-the-game framing, not benchmark tracking.
Reflexivity (Markets): A feedback loop where a market price influences the very outcome it is trying to predict.
Regime: A persistent market state defined not by the calendar but by the combination of volatility, correlation, breadth and momentum. Risk-on, risk-off and transition are the three canonical regimes. Closelook's Money Temperature composite classifies the live regime across calm / warning / stress. See the full Market Regime entry for the Closelook framework.
Resolution (Prediction Markets): The criteria that determine a contract's payout; ambiguous resolution wording is the source of most retail losses.
Revenue Quality: How durable and predictable a revenue stream is: recurring versus one-time, contracted versus cyclical.
Rho: The options Greek measuring sensitivity to interest-rate changes; negligible for most short-dated positions, relevant for LEAPS.
Risk-Off / Risk-On: A regime classification describing capital flowing from risky to safe assets (risk-off) and back (risk-on).
ROCm: AMD's open-source GPU compute platform; the principal alternative to CUDA, but lagging in ecosystem maturity.
Rolling (Options): Closing one option position and simultaneously opening another at a different strike or expiry; the core defensive maneuver for short premium.
RSI (Relative Strength Index): Wilder's 1978 momentum oscillator. Compares the magnitude of recent gains to recent losses and outputs a value from 0 to 100. Above 70 is overbought, below 30 is oversold; divergences between price and RSI often precede reversals. The Pattern Engine flags RSI divergences as one of 51 patterns in the Directional Alpha library.
Rubin 100: Closelook's AI build-out equity index of 100 names across 6 layers and 18 sectors.
Rule of 40: A benchmark stating revenue growth % plus operating margin % should total at least 40; most public SaaS has fallen below it since 2022.
Runway: The number of months until a company runs out of cash, calculated as cash balance divided by monthly net burn.

S

Sales Efficiency: Revenue generated per dollar of sales and marketing spend; an alternative framing of the Magic Number.
Seat-Based Pricing: Per-user-per-month SaaS pricing; structurally vulnerable to agent-driven seat compression as software replaces human operators.
Sentinel Ticker: A Closelook concept: companies at supply chain chokepoints whose data provides early warning for the broader cycle. The three Sentinel Tickers are ASML, Advantest, and Micron.
Settlement (Prediction Markets): The payout phase after a contract resolves; settlement can lag the underlying event by days or weeks.
Sharpe Ratio: Risk-adjusted return: excess return over the risk-free rate divided by standard deviation. A Sharpe above 1.0 is good, above 2.0 is excellent. Closelook reports Sharpe ratios for the ten reference portfolios to enable comparison with benchmarks.
Short Gamma: A dealer or portfolio position whose hedge must be adjusted with the market — buying into strength and selling into weakness — which amplifies price moves.
Six-Layer Model: Closelook's functional segmentation of the AI infrastructure supply chain into six layers.
Skew (Volatility Skew): The difference in implied volatility across strikes; equity puts are typically priced at higher IV than equidistant calls.
Slippage: The difference between the expected execution price and the price actually filled; a major cost in thin or fast-moving markets.
SOFR (Secured Overnight Financing Rate): The US risk-free reference rate that replaced LIBOR; the basis for pricing floating-rate instruments.
Soft Landing / Hard Landing: The two macro outcomes of a tightening cycle: containing inflation without recession (soft) versus triggering one (hard).
Sortino Ratio: A risk-adjusted return measure like the Sharpe Ratio but penalizing only downside volatility; rewards strategies that avoid losses.
Spread (Options Spread): Any options position combining a long and a short option; vertical, horizontal (calendar), and diagonal are the main variants.
SRAM (Static RAM): Faster, more expensive memory than DRAM that needs no refresh; used for on-chip caches close to the processor.
SSD (Solid-State Drive): NAND-flash storage with no moving parts; high-end NVMe SSDs form the data layer for AI training pipelines.
Stablecoin: A cryptocurrency pegged to a fiat currency, usually the US dollar; macro-relevant for dollar demand and crypto liquidity flows.
Stack Flip: A binary state change where price crosses a major moving average, typically the 200-day SMA.
Standard Deviation: A measure of dispersion around an average; the statistical foundation beneath Z-Score, Bollinger Bands, and the Sharpe Ratio.
Strategic Authority Investment: Closelook's framework for trading the constraint language used publicly by NVIDIA leadership; live cohort XIRR +109%.
Strike Price: The agreed price at which the underlying shares change hands if an option is exercised; the reference point for all options pricing.
Substrate: The foundation layer in chip packaging connecting the die to the circuit board; advanced substrates are constrained alongside CoWoS.

T

TAM (Total Addressable Market): The total revenue opportunity a product would capture if it owned 100% of its market. SAM (Serviceable) and SOM (Obtainable) are progressively more realistic subsets. TAM is the ceiling — and when the TAM math stops expanding, the stock's growth multiple compresses. HALO 100 uses TAM expansion as one of four compounder-quality dimensions.
Tape (Closelook Format): Closelook's Monday-Friday live channel of structured market cards with tag-pill filtering.
Term Premium: The extra yield investors demand for holding longer-maturity bonds; it drives the steepness of the yield curve.
Theta: The options Greek measuring daily time decay; the income engine of premium-selling, accelerating in the final 30 days before expiry.
Throughput: The amount of data or work processed per unit time; what bandwidth ultimately enables for AI workloads.
TIPS (Treasury Inflation-Protected Securities): US Treasury bonds whose principal adjusts with CPI; the instrument from which real yields are directly observed.
TOPS (Tera Operations Per Second): An AI inference performance metric counting trillions of operations per second; common in edge and mobile AI specs.
TPU (Tensor Processing Unit): Google's custom AI accelerator ASIC, manufactured with Broadcom; the leading example of hyperscaler custom silicon.
Trend Following: Systematic strategy that buys breakouts and sells breakdowns, assuming trends persist longer than efficient-market theory suggests. The managed-futures industry's canonical approach: momentum + risk parity + small position sizes. Closelook does not run pure trend-following, but the Pattern Engine's 51-pattern library includes moving-average crossovers, channel breakouts and volatility-breakout entries.

U

Unsystematic Risk: Idiosyncratic risk specific to a single company, industry or position — fraud, a lost contract, a failed product launch, a regulatory strike. Diversifiable: adding uncorrelated names reduces unsystematic risk toward zero. Systematic (market) risk cannot be diversified away. Closelook's Reference Portfolios diversify unsystematic risk while preserving thematic systematic exposure.
Usage-Based Pricing: Pricing tied to consumption — API calls, compute, queries; the model agent-friendly software has shifted toward.

V

Vanna: A second-order Greek measuring how an option's delta changes as implied volatility changes — a key driver of dealer hedging when vol moves but price does not.
Vega: The options Greek measuring sensitivity to implied volatility; premium sellers are short vega and profit when IV falls.
Vertical Spread: An options spread using the same expiry but different strikes; defines a fixed maximum gain and maximum loss.
Vig (Vigorish): The house edge built into market prices; how prediction markets and sportsbooks generate revenue regardless of outcomes.
VIX (Volatility Index): The CBOE Volatility Index, measuring expected 30-day volatility of the S&P 500. Higher VIX = more fear. Closelook uses VIX in the Volatility dimension of the Weekly Signal for equity assets. BTC uses DVOL/BVIV instead.
VIXEQ (Constituent Volatility Index): Cboe's gauge of the average expected volatility of S&P 500 members — a 'single-stock VIX'; its gap to VIX reflects implied correlation and dispersion.
Volatility: The magnitude of an asset's price fluctuations, usually as the standard deviation of returns; the generic term above VIX, MOVE, and DVOL.

W

Wafer: The thin silicon disk on which chips are manufactured; wafer allocation is TSMC's primary commercial lever.
Weighted Average: An average where each value carries a weight reflecting its importance. Index construction stands or falls on weighting choice: cap-weighted, equal-weighted, fundamentally-weighted and momentum-weighted give very different portfolios from the same universe. Rubin 100, HALO 100 and Euro-AI 50 publish all three weightings so users can compare.
Wheel Strategy: An income cycle of cash-secured put, assignment, covered call, and call-away, repeated on stocks you want to own.

X

XAU (Gold and Silver Index): The PHLX Gold/Silver Sector Index, tracking the 30 largest precious-metals miners — Newmont, Barrick, Agnico Eagle, Wheaton, Pan American. When XAU breaks out against a weakening DXY, the Money Temperature reads stress-regime signals. XAU is one of eight instruments feeding Closelook's macro temperature composite.
XIRR (Internal Rate of Return): A time-weighted return calculation for irregular cash flows; how Closelook reports cohort performance, e.g. Pattern 03 at +109%.

Y

Yield (Semiconductor): The percentage of usable chips from a wafer; falls with each new node and gates how quickly new processes scale.
Yield Curve: The relationship between interest rate and maturity, typically plotted for US Treasuries from 3-month to 30-year. A normal curve slopes upward; a flat curve signals late-cycle; an inverted curve (short rates above long) has preceded every US recession since 1970 at roughly 12-18 months' lag. The yield-curve slope is one of eight Money Temperature instruments.

Z

Z-Score: Standard deviations from the mean: (x minus mu) divided by sigma. Tells you how extreme an observation is relative to its own history. +/- 2 sigma covers ~95% of normal observations, +/- 3 sigma ~99.7%. Closelook's Cointegration Monitor opens pair trades at +/- 2 sigma on the spread and exits near Z = 0.
