In a world where several companies have market capitalizations well over $1 trillion, what is a small cap anymore?

If you do a quick search query, the most common answer you see on investing websites and other informational sites is $2 billion. In the decade-plus I have been writing about stocks and the market, the consensus was that small caps were less than $2 billion.

But that isn’t the case anymore. The biggest “small cap” in the S&P 600 small cap index is a $9 billion company. The largest small cap in the Russell 2000 is $41 billion (that will undoubtedly change soon). S&P even says in the datasheet for the S&P 600 that the median company size in the index is $1.9 billion.

Yes, the companies in these indices get booted and move up into mid-cap and large-cap indices. Still, the definition of a small-cap isn’t what it was when ExxonMobil was the largest company in the world, with a market value of just over $400 billion.

I say all of this because it leads into my own “Buffett Screen.” This isn’t from a Warren Buffett quote or anything like that. Rather, I developed a screen after reflecting on this 1999 Berkshire Hathaway meeting clip. Initially, I limited the screen to $2 billion, but it’s becoming increasingly apparent that companies that fall into the less than $10 billion bucket are similarly overlooked.

Here are the updated criteria:

  • Trading region of primary security: USA & Canada

  • Market capitalization: Between $1 million and $10 billion

  • Return on total capital over the past 12 months (TTM):  greater than 15%

  • Earnings before interest and taxes margin (TTM): Greater than 10%

  • Price to Free cash flow: Less than 15 times

Let’s dig in.


I will share the results from a stock screen I created using Koyfin.
