2-, 3-, 5-, 7-, 10-, 20- and 30-year Treasury securities, plus TIPS. Announced and tentative dates are labeled; auctions may affect yields, TLT, SPX and QQQ. Verify updates at TreasuryDirect. Future 2027 dates are added only when published, not guessed.

Two-day policy meetings; decisions generally 2:00 PM ET on day two, followed by a press conference around 2:30 PM ET. Future dates are subject to confirmation. Official schedule.

Selected index and ETF options have series expiring on the last trading day of the month, generally PM-settled. EOM is distinct from the standard third-Friday monthly OpEx. Check the specific contract listing and exchange holiday calendar.

The third-Friday quarterly expiration in March, June, September and December, sometimes shifted for holidays. Multiple derivatives expire together, potentially affecting hedging, volume and closing-auction activity. It is different from quarter-end EOM expiration.

At-the-money gamma can rise sharply as expiration approaches; option prices may change quickly for small underlying moves. Time decay also accelerates, particularly for short-dated options.

Implied volatility (IV) is derived from option prices and reflects priced expectations. Realized volatility measures actual historical price movement. IV rank, skew and term structure add context; calendar dates alone do not predict direction.
