Market calendar

The calendar lays the market’s schedule on a familiar month grid: who reports earnings when, which economic numbers drop, which companies are reverse-splitting or going public, and which days the market is closed or closes early.

The five overlays

• Earnings — companies reporting results. Expect their stocks (and sometimes their whole sector) to move that day.
• Economic data — government numbers — inflation, jobs, rate decisions — that can move the entire market at a known minute.
• Reverse splits — a company shrinking its share count (e.g. 1-for-10). Often precedes unusual small-cap behaviour — worth knowing the date.
• IPOs — new stocks starting to trade.
• Market days — holidays, early closes, and options-expiration Fridays, when trading can behave differently.
