Will SPX shares launch higher next week?

The S&P500 has a very strong seasonal pattern from now until the end of April. One of the sayings in Wall Street is โ€˜Sell in May, and go Awayโ€™. It seems that one of the last big pushes in the US index comes as we approach May. The shares are entering a strong time of the year. From April 14 through to May 01 the shares have gained nineteen times in the last twenty five years. The average return has been +2.09% over the last 25 years with a 56.91% annualized growth rate.
