Trading Seasonal Trends: Part 3

 | Jun 01, 2015 10:24AM ET

In Part 1 and I spelled out the historical record of a relatively simple system that uses seasonal trends in the stock market (along with a moving average filter) to decide when to be in or out of the stock market.

Now if my sole intention was to pump up the system and pretend I am some kind of genius I would simply point out that since 1934 a Buy-and-Hold approach has gained 2,822%, while the Seasonal System I detailed gained +33,747%, or +15.8% annually (not including any dividends).

Or I might be more confrontational and ask simply, “How many systems do you know of with an 80-year track record as good as this one?”

But alas, my enthusiasm for being a smug jerk is tempered only by the knowledge that “having a trading system and actually trading said system is not the same thing.” Anyone can come up with a set of trading rules that generate decent results over time. But the real question is “can you follow your trading rules day in and day out” and generate the results you expect? Or to put it another way, note:

One Approach to Trading Using Seasonals

As always, I am not advocating that you trade in the manner I am about to describe. The purpose of this blog is “to provide information”. What you choose to do or not do with said information is – as my sweet Aunt would say “entirely up to you” (Or as my not so sweet Uncle would say, “ain’t my problem.”)

The basic idea is to:

A) Trade the Dow Industrials using leverage when the KTI is +5 or greater and;

B) To trade the Dow Industrial without using leverage if:

1) the KTI is between +2 and +4 AND,

2) the Dow is above its 200-day moving average.

C) Otherwise the system holds cash.

Pretty straightforward and can be accomplished using the following ETFs:

*Dow (no leverage) = Ticker DIA

*Dow (2-to-1 leverage) = Ticker DDM (ARCA:UDOW)

With mutual funds it’s a little trickier because neither ProFunds nor Rydex offers a straight non-leveraged Dow fund (although they do both offer a leveraged Dow fund and a leveraged S&P 500 Index fund).

Whether to use ETFs or mutual funds is up to each individual investor. For this strategy I will mention two things in favor of mutual funds:

A) You can invest exact dollar amounts. For example, if you have $6,982 to invest in an ETF you have to divide $6,982 by the price of one share and figure out how many shares you can buy. With a mutual fund you can buy $6,982 worth of shares.

B) In most cases you will pay a commission when you buy or sell the shares.

So for illustrative purposes, I am going to go with the following portfolio:

*When KTI >= +5 buy and hold ticker UDPIX (ProFunds UltraDow 30)

*When KTI = +2, +3 or +4 AND Dow Jones Industrial Average > its own 200-day moving average hold ticker BLPIX (Bull ProFund which tracks the S&P 500 Index using no leverage)

*When KTI Dow Jones Industrials Average hold cash.

Results

Figure 1 displays the growth of $1,000 invested using this system using UDPIX and BLPIX versus the growth of $1,000 invested in ticker BLPIX on a buy-and-hold basis. The test dates are 6/3/2002 (when UDPIX started trading) and 5/29/2015.

Figure 1 – Growth of $1,000 trading Seasonal System using UDPIX and BLPIX (blue line) versus buying and holding BLPIX (red line); 6/3/2002-5/29/2015.

At first glance the results seem pretty clearly in favor of the Seasonal System. $1,000 invested using the system grew to $3,894 versus just $2,024 for a buy-and-hold approach. Figure 2 displays the year-by-year results for the two methods.
