S&P 500 heatmap by P/Sile
Every company sized by market cap and grouped by sector, coloured by p/sile. Each universe and metric is its own URL, so a particular map is a link. Not investment advice.
How to read it#
Tile area is market capitalisation (net assets for a fund), so the map weights companies the way the market does — the top ten names really are that much of it. Sector bands group the tiles. Returns are price moves for 1D and total returns over longer windows.
FAQ#
- How are the tiles sized?
- By market capitalisation — or net assets for a fund, falling back to dollar volume where neither is known. Area is proportional, so the map shows what the market actually weights rather than treating every company as one square.
- How are the colours chosen?
- Returns colour directly: green up, red down, saturating around ±8%. Valuation metrics colour by RANK across the map instead — a P/E of 30 means nothing until you know what everything else trades at, and one 900× outlier would otherwise flatten every other tile to the same shade. The percentile metrics are the third case: those rank each stock against its OWN ten-year history, which answers a different question again.
- Why can I pick a colour scheme?
- Red/green is the convention and it is also the single most common form of colour blindness. Red/blue, purple/teal and greyscale carry the same information without relying on that pair. The choice rides in the URL, so a shared link keeps it.
