The concentration reference: the seven megacaps that drive index-level returns. Equal-weighted here (deliberately, vs their cap weight in the index) so the basket measures the cohort, not just NVDA and MSFT. Divergence between this basket and the equal-weight index is the concentration trade in one line.
Follow the theme against the wider market.
Series before each basket's creation date are a backtest of the membership as of creation; live tracking starts at creation.

1y · 2025-10-16 – 2026-10-16 · 252 / 252 sessions
Basket total returns · Annualized using 252 trading sessions · 0% risk-free rate and downside target. As of 2026-10-16 · close.
Sharpe: average daily simple return divided by its sample standard deviation, multiplied by √252. The risk-free rate is assumed to be 0%; this is not a cash-adjusted ratio.
Sortino: average daily simple return divided by downside deviation, multiplied by √252. Downside deviation is the square root of the average squared shortfall below 0%, counting all sessions, including zeros for gains.
Historical volatility: √(252 × average squared daily log return), matching the Vol page’s realized-volatility convention. This differs from the sample standard deviation used in Sharpe.
Each period requires complete history and at least 5 sessions. MTD and YTD follow the calendar; 1y is 252 sessions. Missing data or an undefined ratio displays — with a reason. Short periods can produce unstable ratios; intraday snapshots include a partial session. History before this basket’s creation is backtested. If a new basket has no stored daily return series yet, estimates from its rounded published chart levels are marked ≈.
