Small Caps suffer another historic losing streak

By Jason Goepfert

BOTTOM LINE
For a record fifth straight year, Small Caps underperformed Large Caps through Q3. Small stocks trailed Large Caps by more than 10% through Q3 this year, one of the largest divergences in total return since 1928. Those betting on relative mean reversion tended to be frustrated by momentum.

FORECAST / TIMEFRAME
None

Key points:

  • Small Cap stocks underperformed Large Caps through Q3 for the fifth year in a row, a record
  • Other times when the streak reached four years, they tended to bounce back
  • When they underperformed by 10% or more through Q3, mean reversion was much less common

For the fifth year in a row, Small Caps suffer a relative struggle

A couple of weeks ago, we saw that the ratio of smaller stocks to large stocks hit yet another multi-decade low. It has tended to keep going when it reaches this kind of extreme. It has since hovered near its lows.

Through the third quarter, the total return on Small Caps underperformed Large Caps by more than 10%, ranking in the bottom 15% of all years since 1928. This is now the 5th consecutive year that Small Caps underperformed Large Caps through Q3, a record stretch (some of the returns before 1950 were cut off as they were so egregious that they distorted the scale).

There were only three other times that the streak lasted four years, shown in the table below. Even though they underperformed again after the 2022 streak reached four years, their absolute return is still quite positive. 

Relative to Large Caps, they did outperform over the long term when the streak reached four years in 1949 and 1999. Obviously, that failed last year because here we are.

If we ignore the fact that they've underperformed through Q3 for five straight years and just look at the magnitude of the underperformance, the table below shows returns after they trailed Large Caps by 10% or more.

Like other studies we've looked at in recent weeks, it wasn't encouraging for mean-reversion investors. The last few signals were decent, so that's something. But prior to the last 25 years, all of them preceded losses for Small Caps either three or six months later.

Even though recent signals have preceded positive absolute returns, they have still mostly trailed the returns on Large Caps. The last two were the exception - all the preceding signals saw Small Caps continue to underperform Large Caps over the next three months, roughly taking us through year-end.

What the research tells us...

Mean reversion is an irresistible tug for contrarian-minded investors, and when it works, it often works spectacularly. The biggest hurdle is momentum, which is itself a powerful force. For some markets, mean-reversion tends to win, while momentum usually wins in others. Even within markets, it can differ between indexes, sectors, and factors. For Small Caps, there are some compelling bullish arguments, such as relative valuations. Regarding relative price performance, though, it has been hard to find a reliable study that suggests they are a good trade or investment relative to their bigger brothers.

Hypothetical Performance Disclosure: Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any account will or is likely to achieve profits or losses similar to those shown; in fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved by any particular trading program. One of the limitations of hypothetical performance results is that they are generally prepared with the benefit of hindsight. In addition, hypothetical trading does not involve financial risk, and no hypothetical trading record can completely account for the impact of financial risk of actual trading. for example, the ability to withstand losses or to adhere to a particular trading program in spite of trading losses are material points which can also adversely affect actual trading results. There are numerous other factors related to the markets in general or to the implementation of any specific trading program which cannot be fully accounted for in the preparation of hypothetical performance results and all which can adversely affect trading results.
