Day of Week Seasonality Effect
The day of the week seasonality effect in stocks is strong. Some days are simply better than others.
Previously there has been a certain day-of-week seasonality in the S&P 500. Here is a summary of the average gain since 1. January 2010 until the 1st of July based on weekdays:
