Daily, weekly and monthly mean 1, 5 and 21 completed NYSE trading sessions. Returns use Yahoo provider-adjusted closes at both exact endpoints from one accepted retrieval vintage. Missing adjusted prices are unavailable; raw closes and latest snapshots are not substitutes.
Basket return is the mean of covered current members’ returns. The SPY comparison is a difference in percentage points, with the same dates, currency and price basis. SPY is an ETF proxy, not a reconstructed official index.
Volume compares the completed end session with the previous 20 comparable completed sessions for the same usable companies. Missing volumes, split events, mixed retrievals or different session durations make it unavailable. This is not money flow.
Sector names use transparent internal normalization, not licensed GICS. Legacy catalogue classifications have an unknown provider observation date. Primary theme sources describe selected current business roles; their review date is not a membership effective date.
