Welcome to the Stock Market Performance Calendar as measured by the S&P 500 Index. I collected over 20 years of stock market price data and created a 5 year weighted average return for each trading day of the year.  The last 5 years are weighted 3 times the 20 year average.  This will not only show bullish and bearish days, but which ones are big and which ones are small.  I hope you enjoy the calendar and I will post periodically interesting articles on investment ideas.  Please be sure to join this free blog by  submitting your email address below.
