Combining Two Seasonal Strategies into One (Better One?)

  • SumoMe

In this article I wrote about a group of Fidelity sector funds that – as a group – tends to perform well between Nov 1 and Apr 30th

In this article I wrote about two funds that tend to perform well between May 1 and Aug 31st.

So, what happens if we put the two together?

Jay’s Seasonal Combined Portfolio

From Nov 1 through Apr 30 the portfolio holds:

*Chemicals

*Electronics

*Health Care Services

*Construction and Housing

*Retailing

From May 1 through Aug 31 the portfolio holds:

*Health Care

*Long-Term Treasury Bonds

From Sep 1 through Oct 31 the portfolio holds:

*Intermediate-Term Treasuries

Figure 1 displays the funds that were held each month during testing.  FYI, for September and October we simply hold intermediate-term treasuries.

Figure 1 – Jay’s Seasonal Combined Portfolio (Fidelity version)

*For the record, an actual investor at Fidelity would likely use FNGBX (Fidelity Long-Term Treasury) rather than VUSTX (Vanguard Long-Term Treasury).  But VUSTX has a longer track record so I used it in the original test.

Results

The test period extends from 10/31/1986 through 10/31/2019, or 33 years.

Figure 3 displays the growth of $1,000 invested using Jay’s Seasonal Combined Portfolio versus buying and holding the S&P 500 Index.

Figure 3 – Growth of $1,000 invested in Seasonal Combined Portfolio (blue) versions S&P 500 Index buy-and-hold (orange); 10/31/86-10/31/19

For the record, $1,000 using the strategy grew to $354,641 versus $24,972 for the S&P 500 Index.

Summary

So, is the Seasonal Combined Portfolio the “be all, end all” of investment strategies?  Probably not.  As always, I am not “recommending” that anyone rush off and start using this particular strategy because – as the saying goes – past performance is no guarantee of future results. 

Strictly some (hopefully interesting) food for thought.
