What is the Rubin Build-Out 100 index?

A Closelook functional equity index tracking the physical infrastructure buildout powering NVIDIA's Rubin and Feynman platforms — 125 constituents across 8 layers and 24 sectors spanning EDA, foundry, lithography, packaging, memory, power, thermal, interconnects, and data-centre construction.

How many constituents and sectors does Rubin 100 track?

125 constituents across 24 sectors, expanded from 102 in the 2026-06-30 reconstitution. Base date December 30, 2025 = 1,000, with prices converted to USD daily across JPY, EUR, KRW, CHF, TWD and HKD.

What are the four Rubin 100 weighting variants?

Equal Weight (EW, 1/N, quarterly rebalance), Cap Weight (CW, market-cap weighted with a 10% single-stock cap), Momentum (MW, drift since inception with no scheduled rebalance) and Active Momentum (AM, a monthly 21-day-Sharpe selection overlay holding the top 60% of names equal-weight).

What is the Rubin Build-Out 100 index level right now?

As of 2026-08-28, CL-RUBIN-EW (Equal Weight) closed at 1923.07 (-2.59% 1D, YTD +87.09%); CL-RUBIN-CW (Cap Weight) closed at 1679.34; CL-RUBIN-MW (Momentum) closed at 1938.72; CL-RUBIN-AM (Active Momentum) closed at 1937.20.

How the Rubin Build-Out 100 Index Works

Equal Weight (EW)
Each constituent contributes equally (1/N). Rebalanced on the last trading day of each calendar quarter (Mar 31 / Jun 30 / Sep 30 / Dec 31) back to 1/N. Best gauge of average stock performance across the semiconductor supply chain.

Cap Weight (CW)
Weighted by last-known market capitalization (Option B+: price-scaled for backtest deterministically), 10% single-stock cap iterative, same quarterly cadence as EW. Reflects the economic reality where NVIDIA, TSMC, and Broadcom dominate.

Momentum (MW)
Drift since inception: 1/N at base date with no scheduled rebalance — winners compound a heavier weight, laggards shrink. The market does the tilting through price action. First manual semi-annual rebalance scheduled 2026-06-30. The original 21d-Sharpe-monthly methodology is retired (active momentum tilt now lives in Rubin Sector Rotation).

Active Momentum (AM)
Selection overlay: on the first trading day of each month, constituents are ranked by 21-day Sharpe (lagged, no look-ahead); the top 60% are held equal-weight and the laggard 40% are dropped. Currently 75 of 125 names. Rules-based backcast from inception on the as-run universe (61 of 102 before the June 30 reconstitution).

Inception: December 30, 2025 = 1,000. All prices converted to USD daily (JPY, EUR, KRW, CHF, TWD, HKD). 125 stocks across 24 sectors spanning the full AI build-out — from EDA design through memory, power, data-centre construction, and physical AI. Expanded from 102 in the 2026-06-30 reconstitution. Data updates after US market close (~23:00 UTC). Full methodology →

Sector-level rotation strategic positioning

① Biggest sector shifts

Where the trend strength is changing fastest on the selected timeframe, regardless of direction. Arrow indicates whether momentum is building (↑) or fading (↓). The trend descriptor at the end (Strong uptrend / Flat / Strong downtrend...) names the absolute trend state of the sector — distinct from the change shown by Δ.

② Sector directional trend — sequential time windows

Three non-overlapping windows: this week (last 5d), the 3 weeks before that (days 6–21), the 6 weeks before that (days 22–63). Top 5 heating + top 5 cooling per window. Sectors in multiple Up columns = sustained rotation across all three slices. A sector in just one column = the move is specific to that period. Independent of the timeframe toolbar above — this view always shows all three slices.

③ Biggest stock shifts

Individual Rubin names sorted by |Δ| on the selected timeframe. Top 10, mixed direction. The trend descriptor on the right (Strong uptrend / Mild uptrend / Flat / Mild downtrend / Strong downtrend) names the current 252-day Directional-Flow state with magnitude in parentheses — so you read direction + state in words, not just signed numbers.

④ Stock directional trend — sequential time windows

Three non-overlapping windows: this week (last 5d), the 3 weeks before that (days 6–21), the 6 weeks before that (days 22–63). Top 5 heating + top 5 cooling per window. A name in just the recent column = fresh move; in only the older columns = momentum has already faded out of the immediate window; spanning all three = the trend ran the whole quarter. Independent of the timeframe toolbar above.

How this radar works · how to read it

Directional Flow (DF) is Closelook's proprietary trend-persistence metric — a linearly recency-weighted regression on log(close) over ~252 trading days. The slope, annualised in %, becomes the DF level. Recent bars get higher weight, so the number reflects where the stock is trending now, not where it spent the year. Range typical: −100 to +300.

Δ_N (Δ5, Δ21, Δ63) is the change in DF level over the past N trading days — this week, this month, the past quarter respectively. Positive Δ = trend strengthening. Negative Δ = trend weakening. Because price reacts last, trend strength is coincident, and the change in trend strength leads — Δ surfaces acceleration and fade before the level catches up.

Display 1 — Biggest shifts (panels ① and ③). Names where trend strength is moving fastest on the picked timeframe, regardless of direction. The toolbar selects which Δ_N is used. Each row carries: ticker / name / Δ value / arrow (↑ momentum building, ↓ momentum fading) / the absolute trend descriptor in words (Strong uptrend, Mild downtrend...) so you don't have to mentally decode the level.

Display 2 — Sequential time windows (panels ② and ④). The cumulative Δ5/Δ21/Δ63 are nested windows — Δ63 includes Δ21 includes Δ5 — so a steady uptrend dominates every column. We fix that by showing the matrix in non-overlapping windows: this week (last 5d, the bare Δ5), prior 3 weeks (days 6–21, computed as Δ21 − Δ5), prior 6 weeks (days 22–63, computed as Δ63 − Δ21). Each column now shows a distinct time slice. The toolbar timeframe does not change the matrix — all three slices are always present.

Up in all three columns of the matrix → momentum strengthened during this week AND the 3 weeks before AND the 6 weeks before. A sustained ride. For sectors: strategic allocation candidate. For stocks: high-conviction tactical buy.
Up only in "this week" → fresh acceleration on top of an otherwise quiet quarter. Early signal. Confirm with price before sizing up.
Up in "prior 6w" only, Down or flat elsewhere → the move ran 1–2 months ago and has since faded out of the recent window. Distribution candidate.
Up "this week", Down "prior 6w" → reversal candidate. Could be bottom-fishing or could be a dead-cat bounce — needs context from sector and macro.
Strong uptrend descriptor + negative Δ → trending hard at the absolute level, but decelerating right now. Long warning, trim candidate.
Strong downtrend descriptor + positive Δ → still in net downtrend, but momentum building. Early-recovery candidate.

Granularity. Sector-level is for strategic positioning — which slices of the Rubin universe are rotating in or out. Stock-level is for tactical positioning — which individual names to enter or exit. Region / Market Cap / Thesis Role are auxiliary cuts of the same flow data, useful for geographic / size / strategic-role tilts.
