Question of the Day: How much would a $100 investment in Warren Buffet's company in 1964 be worth in November of 2020?

Answer: About $2.8 million

The math:

  • From Berkshire Hathaway Annual Letter to investors: Overall gain from 1964 to 2019: 2,744,062% 
  • At end of 2019, that $100 would be worth $2,744,162
  • Berkshire stock performance (through 11/9/20): 0.87% bringing investment's value close to $2.8 million


  1. Do you think it is easy/difficult to hold on to investments like this over the long-term? Explain.
  2. If you had the chance to meet Warren Buffett, what are two questions that you would ask him?
  3. Investors spend a lot of time looking for the next Warren Buffett. Do you think that is time well spent? Explain.
  4. Researchers often find that investors do vastly worse than if they had just made the simple choice to own an index fund (like the S&P 500). What might be some of the reasons they do so poorly?

Behind the numbers (from Berkshire Hathaway Annual Report): 

  • Compounded annual growth rate (CAGR) of 20.3% for period 1965-2017. 
  • S&P 500 CAGR was 10.0% over that same period. 


While the value of stock in Warren Buffett's company was driven by his stock picking prowess, Buffett has consistently told investors "do as I say and not as I do" in espousing the value of index funds. Here's his conversation with Lebron James where he provides an answer on how 99% of the population should invest.
