Market seasonality almanac · v2026.07.15

Koyomi

A market almanac built on decades of monthly data: which months historically close green, how wild each month tends to be, and where the current year sits in its cycle. Covers Bitcoin and the crypto market, global stock indices, metals and currencies — plus how the month in progress compares to every version of it on record. Educational only: history is context, not a promise.
