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 | +6.27% | +1.34 | -2pp | -0.77pp | Confirming ↑ |
| 1 month | +3.79% | +0.81 | -6pp | +0.40pp | Confirming ↑ |
| 1 quarter | -10.69% | -2.17 | -7pp | +0.06pp | Confirming ↓ |
Over the last 126 sessions: price up +53.36%, breadth up (+5.04/name) · % beating 46→36 · median−ETF -1.16pp→-2.50pp.
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 2026-09-24.
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 | 39 (31%) | 16 (13%) | +23 |
| 1-Month | 14 (11%) | 1 (1%) | +13 |
| 3-Month | 3 (2%) | 1 (1%) | +2 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -0.53% | -0.22% | +0.30pp | 55 / 70 | 70 / 55 | 48 of 125 | ±3.22% |
| 5d | +6.27% | +6.17% | -0.10pp | 115 / 9 | 60 / 65 | 14 of 125 | ±6% |
| 21d | +3.79% | +1.90% | -1.89pp | 81 / 44 | 54 / 71 | 7 of 125 | ±10.35% |
| YTD | +104.22% | +60.62% | -43.60pp | 117 / 5 | 34 / 88 | 1 of 122 | ±113.35% |
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 2026-09-24: over 21 sessions the fund returned +3.79% while its median constituent returned +1.90% — a dispersion of 10.35 pp; 43% of 125 members beat the fund. Broad advance - breadth is rising with price.
How did RUBIN's members trade in the last session?
As of 2026-09-24: fund -0.53%, median member -0.22%, 55 advancers vs 70 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?
