Fast Start Historically Good For December Stock Market Returns

This was the best start to the month of December for the S&P 500 in five years. This got me thinking, is this a good sign or a bad sign for stocks?

Remember, I noted why a big drop on the first day of September was a bad sign for stocks and that played out well.

As I’ve noted several times over the past few days, December stock market returns are usually strong and the month of December rarely has as a big down month. Strength in December is often called the ‘Santa Claus’ rally.

Since 1950, December is the best month and has the smallest average loss when it is red.

But does a 1% gain on the first trading day tell us anything? Turns out, it is actually a very good sign.

Since 1950, the average December stock market returns after the first day of the month is +1.73%. Not bad, not bad at all.

Here’s where it gets good. After a >1% gain on the first trading day of the month, the average and median December stock market returns for the rest of the month actually get stronger!
