Thoughts on the investment question Buffett asks daily and the three questions he considers each week

In November 2022, the 32nd Annual Graham and Dodd Breakfast featured Todd Combs, one of the two portfolio managers allocating capital for Warren Buffett.

In it, Combs explained how one question is constantly asked, usually daily, and that is:

“Is the moat wider or narrower on any of their businesses?”

Furthermore, he highlighted that he goes to Buffett’s house on many Saturdays to talk, and here’s a litmus test they frequently use.

Warren asks :

  1. “How many names in the S&P are going to be 15x earnings in the next 12 months?
  2. How many are going to earn more in five years (using a 90% confidence interval), and 
  3. How many will compound at 7% (using a 50% confidence interval)?” 

In this exercise, you are solving for cyclicality, compounding, and initial price. This rubric was used to find Apple, since at the time the same 3-5 names kept coming up.

In order to better understand why Buffett might be asking these questions, we might ask:

  1. What percentage of companies in the S&P 500 have historically traded at or above a 15-times earnings multiple?
  2. How many companies in the S&P 500 earn more in 5 years than they are currently? And how much does this number vary by year?
