Using daily S&P 500 data from 1975 to 2024, the analysis evaluates the turn-of-the-month effect, preholiday returns, Federal Reserve meeting dates, earnings intensity and seasonal expected returns. Each effect is tested individually and then integrated into a unified strategy. While individual anomalies exhibit modest and time-varying performance, their combination concentrates returns into specific trading windows and improves risk-adjusted performance relative to buy-and-hold, showing the economic importance of predictable timing patterns in equity returns.engCalendar effectsSeasonal momentumEarnings announcementsFOMC meetingsSeasonal momentum: calendar effects and market eventsmaster thesis204242347
