Constituent dispersion · breadth vs the index
RUBIN — Rubin Build-Out 100 (EW)
Divergence over time — price vs breadth, by horizon
The hero read is the 1-month picture; here the same price↔breadth divergence across 1 week / 1 month / 1 quarter, computed over the 126-session history. A/D /name is net advancers-minus-decliners per covered constituent; % beating Δ and median−ETF Δ show how participation shifted. Price rising while those fall = the move is narrowing under the surface.
| Horizon | Price | A/D /name | % beating Δ | Median−ETF Δ | Read |
|---|---|---|---|---|---|
| 1 week | -4.94% | -1.34 | +9pp | +3.49pp | Confirming ↓ |
| 1 month | -6.69% | -1.19 | +7pp | +1.95pp | Confirming ↓ |
| 1 quarter | -9.52% | -2.84 | +13pp | +3.76pp | Confirming ↓ |
Over the last 126 sessions: price up +45.37%, breadth up (+3.98/name) · % beating 34→50 · median−ETF -3.67pp→+0.03pp.
Stocks above their moving average — participation breadth
Of the 125 covered constituents, the share trading above each simple moving average — the classic breadth gauge. A firm index price with a low %-above-MA is a narrow, top-heavy tape. As of 2026-09-03.
New highs & new lows — by horizon
How many of the 125 covered constituents closed today at a new high (or low) over each window, and the net. A shrinking net as the index holds up = fewer names leading.
| Horizon | New highs | New lows | Net |
|---|---|---|---|
| 5-Day | 23 (18%) | 37 (30%) | -14 |
| 1-Month | 3 (2%) | 22 (18%) | -19 |
| 3-Month | 2 (2%) | 6 (5%) | -4 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.04% | +0.16% | +0.20pp | 69 / 56 | 70 / 55 | 68 of 125 | ±2.26% |
| 5d | -4.94% | -4.46% | +0.48pp | 16 / 109 | 71 / 54 | 29 of 125 | ±5.38% |

Median − ETF below zero means the typical name is lagging the cap-weighted index — the move is top-heavy. "Beat" counts constituents outperforming the ETF over the window. Dispersion is the cross-sectional standard deviation of constituent returns — high = a stock-picker's tape, low = pure beta.
What drove the move — contribution = weight × return

FAQ · from the current data
RUBIN dispersion — data Q&A
Is RUBIN's move broad or carried by a few names (21 sessions)?
As of 2026-09-03: over 21 sessions the fund returned -6.69% while its median constituent returned -5.93% — a dispersion of 9.74 pp; 53% of 125 members beat the fund. Broad decline - breadth is falling with price.
How did RUBIN's members trade in the last session?
As of 2026-09-03: fund -0.04%, median member +0.16%, 69 advancers vs 56 decliners.
What does the dispersion page for RUBIN measure?
It splits the fund into its members: the fund's own return against the median constituent, how many members beat the fund, advancers vs decliners, and a cumulative advance/decline line that tends to lead price. A firm fund price with a weak median and a falling A/D line is a narrow, top-heavy tape; a broad move shows the median keeping up. 125 constituents covered, re-baked nightly from the Closelook lake.
Is this investment advice?
