April’s Fool Day Phenomenon

By Lawrence

One of the very rare calendar date based statistical bias happens on April’s Fool. No joke!

The Phenomenon

March 30 and March 31 each date produces an accumulated -15% return (non-compound, close to close) on Dow or S&P 500.

Then on April’s Fool, a whooping +15%. It is not the strongest performer in terms of calendar date bias, but definitely enabling the market to wipe out the losses made in the 2 prior trading days.

Maybe the stock market likes to pull a prank on its players too.

Note: Data collected over the past 50 to 60 years.
