Over the past 50 years, the S&P 500 Index has closed higher in April 70% of the time, averaging a gain of 1.5%. Historically, the first trading day in April is one of the strongest days of the year for the S&P 500 Index. During the past 20 periods, the S&P 500 Index gained 0.8% per period. A major reason is money flows entering the equity market coming from pension plans on the first trading day of Q2.
