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 | -2.16% | +0.3 | -3pp | +0.24pp | Improving |
| 1 month | -2.90% | -0.64 | -2pp | +0.43pp | Confirming ↓ |
| 1 quarter | -23.14% | -4.57 | +5pp | +3.45pp | Confirming ↓ |
Over the last 126 sessions: price up +45.56%, breadth up (+3.33/name) · % beating 37→39 · median−ETF -2.00pp→-1.76pp.
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 2026-09-17.
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 | 25 (20%) | 10 (8%) | +15 |
| 1-Month | 8 (6%) | 6 (5%) | +2 |
| 3-Month | 1 (1%) | 4 (3%) | -3 |
| 6-Month | 1 (1%) | 2 (2%) | -1 |
| 52-Week | 1 (1%) | 0 (0%) | +1 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | +1.53% | +1.36% | -0.17pp | 86 / 39 | 58 / 67 | 41 of 125 | ±2.75% |
| 5d | -2.16% | -1.76% | +0.40pp | 32 / 92 | 67 / 58 | 24 of 125 | ±4.79% |
| 21d | -2.90% | -6.86% | -3.97pp | 30 / 95 | 43 / 82 | 6 of 125 | ±10.46% |
| YTD | +92.13% | +50.12% | -42.01pp | 114 / 8 | 33 / 89 | 0 of 122 | ±103.37% |
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 2026-09-17: over 21 sessions the fund returned -2.90% while its median constituent returned -6.86% — a dispersion of 10.46 pp; 34% 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 2026-09-17: fund +1.53%, median member +1.36%, 86 advancers vs 39 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?
