Where the strength
is hiding in plain sight.
Relative strength for every sector, industry and equal-weight ETF in the book, measured against the S&P 500 — a five-day relative return, plus 25- and 63-session percentiles. Rebuilt from Unusual Whales every five minutes, one click from your sheet.
One tile per ETF, lit by 25-session relative strength
Method & provenance
How it is measured
Every ETF is measured against SPY. RS 1W is the five-day relative return of the ETF/SPY ratio. RS 1M and RS 3M are the percentile of today's ratio inside its own 25- and 63-session history — 100% means it has never been stronger against the index in that window.
Where the numbers come from
Daily bars and live quotes come from Unusual Whales. Ticker lists, sector labels and names are read from the Market Review Google Sheet, which refreshes on demand from the same source. On every refresh the engine reproduces the sheet's own figures at the session the sheet holds — that check is reported below.
The refresh chain
Refresh chain ticks the sheet's checkbox; the EC2 job then fetches, writes and sorts the sheet, after which this page re-pulls its own snapshot. Auto-refresh runs every five minutes.
