The Christmas Strategy Remains Bullish

December 5, 2016 5:00 am1 commentViews: 2713
With Christmas just a few weeks away, I thought it would be interesting to see how the S&P behaves in the days just before Christmas. Do the days just before this holiday tend to be bullish, bearish, or neutral?
To test the market behavior just before the Christmas holiday I will use the S&P Cash index back in 1960. I will create an EasyLanguage strategy that will enter a trade X days before Christmas and close that trade on the opening of the first trading day after Christmas.  Each trade will dedicate $50,000 to purchase shares. Stops, and both commissions and slippage are not utilized in this study.

Ten Days Before Christmas

First let’s look at the ten days before Christmas. What happens if we enter a trade X days before Christmas and close that trade on the open after Christmas? By using TradeStation’s optimize feature I can systematically test each day over the historical data. The results of each test is the generated P&L for each iteration and is depicted in the bar graph below. Looking at the graph, each bar on the x-axis represents the number of days before Christmas.
It appears that the 10 days before Christmas all show positive P&L. In general, the longer you’re holding period before Christmas the better.

Ten Days After Christmas

Using a similar trading system, I will look at entering a trade on open of trading day following Christmas and holding that trade for X days. Below is a bar graph showing the days 1-10 after Christmas. Again, each bar represents P&L and the x-axis is the number of days the trade is held.
Historically, all days after Christmas in our study have returned positive results. Unlike the 10-days before Christmas, in this case it appears there is not much gain for holding beyond five days.

The Christmas Trade

Based on the information above, which seems to show a strong bullish biased for the days immediately before and after Christmas, I’m going to create another strategy that will open a trade five days before Christmas and closes that trade five days after Christmas. I picked five days simply because it was the middle value (1-10) for the days before and after Christmas we tested.  Last year’s Christmas Trade (December 2015) was a winning trade. It’s pictured below.

Here is the trade from the year 2014. It was a losing trade.

The Christmas Trade for 2013 was a winning trade and it looked like this.

When you combine all the trades going back to 1966 we get the following equity curve and performance.

Bull/Bear Regime Filter

How does the overall market regime affect the performance of this strategy? I decided to test this strategy using a 200-day simple moving average (SMA) to divide the market into a bull or bear regime. I first tested taking trades only when the market is within a bull regime (above the 200-day SMA) then tested taking trades when the market is in a bear regime (below the 200-day SMA). Below is the table with the results.

The results show the Christmas edge holds up well for both regimes. There is really no clear loser when it comes to taking trades during a bull or bear market.

Conclusion

There certainly does seem to be a very strong bullish tendency around Christmas. Can you take advantage of this in your trading? Perhaps. Remember, the code provided below this article is not a complete trading system, but an indicator to help me gauge the market behavior around the Christmas holiday. If you have trading systems or trade a discretionary method around these days before and after Christmas, you might use this knowledge to ignore short signals, or modify your exit.
