Some investors heavily rely on seasonal investing. But does seasonality really work? Let’s explore.
One major seasonality strategy is known as the Best Six Months. Ever hear of the phrase “Sell in May and go away?” Below is a bar chart of monthly historical returns for S&P500.

And so far this year, seasonality has been on track for the S&P500:
When looking over long periods of time, investing from Nov 1st to April 30th (ie. the Best Six Months) would outperform investing from May 1st to Oct 31st. In fact, let’s suppose there are two people who invested $10,000 into the S&P 500 back in 1960. Person A invests only in the best six months while Person B invests in the remainder six months. The chart below shows how the two fared.

Other seasonal strategies that have been shown to outperform the stock market are:
- Oil prices from Feb to May
- Gold prices from July to Sept
- Tech stocks from Oct to Jan
- Consumer staple stocks from May to Nov
There’s a convenient ETF that exploits seasonality by rotating investments in several asset classes such as equities, bonds, commodities and cash. It’s called Horizons AlphaPro Seasonal Rotation ETF (Ticker: HAC:TSX). As seasonal periods are never the same, this ETF is also supported by additional fundamental and technical analysis. Below is a chart showing the performance of HAC since inception almost 2 years ago.

Although this ETF is convenient, there are some downsides such as:
- Low trading volume
- High fee – although much lower than mutual funds.
- No backtest data – There’s only 2 years of data so we don’t know how this ETF would have performed during the 2008-09 decline. One possible approach to limiting risk with this ETF is to combine it with the 200-SMA strategy we discussed.

We’ve now covered trend-line (including moving averages), Shiller P/E and seasonality strategies on this blog. In the future, we’ll also take a look at sentiment and sector rotation strategies. These basic technical tools should help give you a lot more confidence when managing risk in volatile markets.
