What he found was there was a high correlation between the S&P 500’s returns between November 19th and the following January 19th and the S&P’s performance the 12 months following January 19. And since the 2-month period straddled the turn of the year and the gift giving season, he called it the TOY Barometer [...] if Nov 19 is on a weekend, use the Monday after the weekend, and if Jan 19 is on a weekend, use the Friday before). He only considered the price-only return (no dividends). If the return during this 2-month period was greater than 3%, a bullish signal was given, and the market was very likely to do well over the following 12 months. If the return was 0-3%, the signal was considered neutral, and results were somewhat random and in line with what is considered average. And if the return was negative, a bearish signal was given, and returns tended to be very poor.
Neutral Signals: There have been 19 neutral signals. The following year was positive 12 times (63%), compared to 73% win rate for “all years.” The overall average and median returns were 6.0% and 7.1%. But among the “up” years, the average and median gains were 14.4% and 9.4%, while the “down” years’ average and median losses were -8.5% and -7.8%. There were several big up years (1995, 1996, 1998, 2003), and two big down years (1973, 1977), so even if there is a neutral signal, there’s still a decent chance the following 12 months will venture far from its January 19 print.
Bearish Signals: There have been 16 bearish signals. Only 6 (38%) of the following years posted a gain while 10 posted losses – and 6 of those 10 posted double digit losses. The overall average and median returns were -3.6% and -6.0%. The “up” years posted average and median gains of 14.6% and 15.5%, while the “down” years posted average and median losses of -14.6% and -12.9%. So despite the low win rate, when the market does well, it has the ability to do very well, as was the case this past year.
[...] When a bullish signal is in play, odds heavily favor solid gains over the following 12 months, but when there’s a bearish signal, odds favor a down year with a relatively big loss. But regardless of the signal, “up” years tend to be very good.
