- 3. Use Movers for what shifted lately; Reports for a written pass three times a week.
Ratio vs S&P 500
Each ETF's closing price divided by SPY (or the site benchmark). A rising ratio means that ETF is outpacing the US large-cap market; a falling ratio means it is lagging. Absolute dollar levels are not the signal.
Own-history percentile
Today's ratio ranked among every trading day in that same ETF's trailing window (about a decade, or since inception). “Near lows (5%)” means lower than on 95% of those days — for that fund only. We never say one sector is “cheaper” than another.
Near lows / Near highs
Plain-language labels for the percentile. Left on charts = toward own lows; right = toward own highs. Parentheses show the exact percentage. This is a position in a range, not a valuation multiple and not a trade idea.
Extremes
Funds currently furthest toward their own lows or highs. Useful for scanning, not for ranking “best bargains across the market.”
Movers
Largest recent changes in that own-history percentile (about 1 week and 1 month). Drift inside a fund's range — not absolute return and not peer ranking.
Heatmap
All covered ETFs colored by own-history percentile. Cooler tones lean toward lows; warmer toward highs. Color is never a buy/sell signal.
Reports
Written notes on Mondays, Wednesdays, and Fridays that flag the biggest shifts within categories. Same data as the dashboard; narrative only.

What we never claim
Cheap, expensive, undervalued, overvalued, buy, sell, or that one category is “better value” than another because its PE or percentile looks lower. Structural differences between regions and sectors are real — that is why each asset has its own history.
