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 | -9.86% | -2.24 | +3pp | +1.21pp | Confirming ↓ |
| 1 month | +4.91% | +1.85 | +9pp | +2.21pp | Confirming ↑ |
| 1 quarter | -0.77% | -0.07 | +3pp | +1.15pp | Weakening |
Over the last 126 sessions: price up +13.22%, breadth down (-0.76/name) · % beating 38→54 · median−ETF -6.77pp→+1.23pp.
Stocks above their moving average — participation breadth
Of the 129 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 2026-10-14.
New highs & new lows — by horizon
How many of the 129 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 | 5 (4%) | 103 (80%) | -98 |
| 1-Month | 4 (3%) | 31 (24%) | -27 |
| 3-Month | 0 (0%) | 9 (7%) | -9 |

Dispersion by window
| Window | ETF | Median | Median − ETF | Up / Down | Beat / Lag | ±1% band | Dispersion |
|---|---|---|---|---|---|---|---|
| 1d | -3.21% | -3.10% | +0.12pp | 22 / 104 | 68 / 61 | 26 of 129 | ±3.23% |
| 5d | -9.86% | -10.77% | -0.91pp | 8 / 121 | 62 / 67 | 11 of 129 | ±6.49% |

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 2026-10-14: over 21 sessions the fund returned +4.91% while its median constituent returned +4.30% — a dispersion of 9.86 pp; 47% of 129 members beat the fund. Broad advance - breadth is rising with price.
How did RUBIN's members trade in the last session?
As of 2026-10-14: fund -3.21%, median member -3.10%, 22 advancers vs 104 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. 129 constituents covered, re-baked nightly from the Closelooknet lake.
Is this investment advice?
