Halloween is fast approaching and, like everyone else, I'm thinking about my costume. In the past I've worn Lucha Libre masks and cowboy outfits, but generally I like it creepy. One of my favorites was the year when I donned a horned goblin mask, doctor's coat and carried two very large and old pipe wrenches. As regular readers of my articles, you know that I can tie the stock market to just about everything and Halloween is no exception.
Actually, the stock market and Halloween have a long-documented association. The Halloween Effect is one of many "Seasonal Anomalies". Dr. William Ziemba, among others, is well known for his work on seasonal stock market anomalies, including the Halloween Effect. In a nutshell, the Halloween Effect consists of buying the market six trading days before Halloween and selling come May 1st. The market could be bought using either S&P 500 or Russell 2000 futures or ETFs.
In The Handbook of Equity Market Anomalies, Ziemba explains that a buy and hold strategy returned 96% for the S&P 500 and 204% for the Russell 2000 from February 1993 through the end of 2010. Yet, if you followed the Halloween Effect rules and bought in late October, sold in May and held cash until late October rolled around and rinsed and repeated from 1993 to 2010, you would have earned 373% for the S&P 500 and 494% for the Russell 2000. These results include both stock dividends and interest earned on a cash position. Here are the results side by side:
As the above results illustrate, you could have more than doubled your money trading the Halloween Effect as opposed to a Buy & Hold strategy. You have to be diligent, though, and trade by the rules. One deviation from the strategy, wherein you decide to hold during the summer or wait too long to buy, could significantly change results. As with any investing strategy, you need to be disciplined.
Over the years, researchers have tired to understand this persistent anomaly. Some of their theories indicate summer vacations, Seasonal Affective Disorder and seasonal optimism as reasons for its success. Most of the research points to changes in investors' risk tolerances. Supposedly, investors are more wiling to take risks when they are optimistic. Stronger risk appetites lead to more cash finding its way into the stock market. Higher stock returns are, therefore, generally the result.
There are several investment vehicles that allow you to take advantage of the Halloween Effect. These include the following (Remember: buy right before Halloween and sell on May 1st each year).
SPY SPDR® S&P 500 ETF
The SPDR® S&P 500 ETF is a fund that generally corresponds to the price and dividend performance of the S&P 500 Index before expenses.
IWM Russell 2000 Index Fund
The iShares Russell 2000 Index Fund seeks investment results that correspond generally to the price and dividend performance of the Russell 2000 Index before expenses.
IWV Russell 3000 Index Fund
The iShares Russell 3000 Index Fund seeks investment results that correspond generally to the price and dividend performance of the Russell 3000 Index before expenses.
TNA Direxion Small Cap Bull 3X Triple-Leveraged ETF
For those with a bigger appetite for risk, the Direxion Small Cap Bull 3X Triple-Leveraged ETF is designed to yield investment results approximately equivalent to triple (300%) the return of an investment in the Russell 2000 Index before expenses.
CLF Cliffs Natural Resources Inc.
I actually found a stock that usually performs well from November to April, then very often tanks from May through summer. Cliffs is a mining and natural resources company that produces iron ore and metallurgical coal products. There must be some strong seasonality in both iron ore and the stock price of this company.
In conclusion, the next time your neighbors pepper their yards with inflatable ghosts, ghouls and black cats, and your mailbox fills up with invitations to costume and pumpkin-carving parties, consider these to be signals that it's just about time to awake your dead cash from its tomb and bring it to life in the stock market.
