The chart of the week analyzes the first 50 trading days of the year when the S&P 500 returned 5% or more. Out of the last 25 occurrences, the market has been positive for 24 times of the remainder of the year, which is a 96% success rate. Additionally, the average return during these periods is significant, at 12.6%. The only exception was in 1987 when the infamous Black Monday stock market crash happened. Although this is based on historical data, a 24/25 success rate definitely gains your attention.
