If you’re investing small sums, you can earn the highest returns by focusing on microcap stocks. That’s why many top value investors started in micro caps. For instance, Warren Buffett concentrated on micro caps when he managed his partnership starting in 1957, which produced the highest returns of his career. And Buffett has repeatedly said that in today’s market, he could get 50% per year if he could invest in micro caps.
Look at this summary of the CRSP Decile-Based Size and Return Data from 1927 to 2020:
|Decile||Market Cap-Weighted Returns||Equal Weighted Returns||Number of Firms (year-end 2020)||Mean Firm Size (in millions)|
(CRSP is the Center for Research in Security Prices at the University of Chicago. You can find the data for various deciles here: http://mba.tuck.dartmouth.edu/pages/faculty/ken.french/data_library.html)
The smallest two deciles – 9+10 – comprise microcap stocks, which typically are stocks with market caps below $500 million. What stands out is the equal weighted returns of the 9th and 10th size deciles from 1927 to 2020:
Microcap equal weighted returns = 15.8% per year
Large-cap equal weighted returns = ~10% per year
In practice, the annual returns from microcap stocks will be 1-2% lower because of the difficulty (due to illiquidity) of entering and exiting positions. So we should say that an equal weighted microcap approach has returned 14% per year from 1927 to 2020, versus 10% per year for an equal weighted large-cap approach.
Still, if you can do 4% better per year than the S&P 500 Index (on average) – even with only a part of your total portfolio – that really adds up after a couple of decades.
- Most professional investors ignore micro caps as too small for their portfolios. This causes many micro caps to get very cheap. And that’s why an equal weighted strategy – applied to micro caps – tends to work well.
VALUE SCREEN: +2-3%
By adding a value screen to a microcap strategy, it is possible to add at least 2-3% per year. There are several ways to measure cheapness, such as low EV/EBIT, low P/E, and low P/CF.
IMPROVING FUNDAMENTALS: +2-3%
You can further boost performance by screening for improving fundamentals. One excellent way to do this is using the Piotroski F_Score, which works best for cheap micro caps. See: https://boolefund.com/joseph-piotroski-value-investing/
If you invest in microcap stocks, you can get about 14% a year. If you also use a simple screen for value, that adds at least 2% a year. If, in addition, you screen for improving fundamentals, that adds at least another 2% a year. So that takes you to 18% a year, which compares quite well to the 10% a year you could get from an S&P 500 index fund.
What’s the difference between 18% a year and 10% a year? If you invest $50,000 at 10% a year for 30 years, you end up with $872,000, which is good. If you invest $50,000 at 18% a year for 30 years, you end up with $7.17 million, which is much better.
BOOLE MICROCAP FUND
An equal weighted group of micro caps generally far outperforms an equal weighted (or cap-weighted) group of larger stocks over time.
This outperformance increases significantly by focusing on cheap micro caps. Performance can be further boosted by isolating cheap microcap companies that show improving fundamentals. We rank microcap stocks based on these and similar criteria.
There are roughly 10-20 positions in the portfolio. The size of each position is determined by its rank. Typically the largest position is 15-20% (at cost), while the average position is 8-10% (at cost). Positions are held for 3 to 5 years unless a stock approaches intrinsic value sooner or an error has been discovered.
The mission of the Boole Fund is to outperform the S&P 500 Index by at least 5% per year (net of fees) over 5-year periods. We also aim to outpace the Russell Microcap Index by at least 2% per year (net). The Boole Fund has low fees.
