Sixteen markers, seventy years of data, and charts built to be hovered. It all still works, but it’s best viewed on a desktop, not mobile.
Pillars group the markers by what they measure; the headline average still weights all 13 equally. A pillar is extreme when at least half its markers are above their own 90th percentile. Each card shows today’s reading and the S&P 500’s subsequent price return from each level.
These series are shown for context and never enter the score — some are too short to clear the five-year rule, others are secular trends that would sit permanently at a record. Today the S&P 500 sits above its 200-day average and the Nasdaq-100 . Those are the naked stretch numbers; the scored version is their persistence.
