Let’s face it – we all love Christmas time. Here in Australia, we are lucky enough to spend most of this time on holidays, enjoying time with our families in the hot summer and having a bowl down the backyard cricket pitch as we watch the boxing day test. For a professional investor like me, December is often a time where I can make some big gains on my portfolio from the gift known as the Santa Claus rally. This seasonal phenomenon can often occur in the latter parts of December – the challenge is timing your way into this market so that you don’t miss out on the action.
Let’s take a look at what the stock market typically does in December:

Taking a look at the 15th of December through to the 1st of January, the ASX over the last 30 years or so has seen some exceptional gains more often than not. The stats below, according to our seasonal screener known as ‘Seasonax’, speak for themselves throughout this period:

The market trades higher through this period around 86% of the time and averages a gain of 2.43% – they’re some pretty good odds if you ask me!
So, you may be thinking, why does this happen? Why is the market so bullish throughout this period? Well, the answer really boils down to one thing – a lack of change to economic policy. We know that the RBA meets every month on the first Tuesday to discuss economic policy and potentially alter interest rates, except there is no meeting in January. This results in traders having more certainty surrounding the economic landscape as they head into the back end of the year, and with more certainty comes more of a proclivity to buy shares – pushing prices higher. Whilst the RBA takes their holiday break, this is a time where you could be making some serious gains.
Now hold your horses – just because the market typically makes gains through late December does not mean you pile into any old stock on the 15th of December. Firstly – you need to time the market better than this so that you put yourself ahead of the average investor. My advice would be to consider entering the market in September (usually one of the weakest months) or late November, where you may be able to pick up some bargains. Secondly – make sure to buy the right asset. Holding the right kind of shares in your portfolio is critical and can make or break your overall performance.
