Warren Buffett’s Strategy vs. Quality Asset Management’s

Warren Buffet is one of the greatest investors of all times. Given that his fund, Berkshire Hathaway, holds a small number of stocks, you may think that his strong performance was the result of superior stock selection (a.k.a. alpha). A study that was published in 2013 (https://www.nber.org/papers/w19681) found that the benefit of his stock selection was statistically insignificant, attributing virtually the entire performance to structural decisions. Below I review the sources of his performance that are in common with Quality Asset Management (QAM), and those that are different.

In common:

  1. Value: Both invest in companies with a low price relative to the company’s book value (low P/B).
  2. Quality: Both invest in profitable companies.
  3. Reduced Volatility: Buffett buys low volatility stocks that historically resulted in excess returns. QAM achieves similar results (reduced volatility, excess returns) by excluding extremely small and expensive (high P/B) stocks as well as stocks experiencing negative momentum.

Buffett’s benefits:

  1. Leverage: Buffett employs leverage of 1.4 to 1.6, with very low costs of borrowing thanks to using capital from his insurance business (premiums received until claims where paid), and interest-free loans: differed tax on depreciation, accounts payable and option contract liabilities. QAM helps clients use home mortgages & HELOCs (home equity lines of credit) to generate leverage, when desired, possible (the client can qualify for the loans) & subject to a risk analysis. In addition, it invests deferred obligations, including income taxes until due (e.g. when the client pays 110% of past year’s taxes in estimated taxes, and enjoys faster growing income). QAM uses very low cost margin for loans backed by unused HELOCs, and other sources. While there are some similarities, this strategy is not used for all of QAM’s client’s, and the leverage level declines with the growth of the portfolio relative to the client’s home value. In addition, the interest rate that Buffett gets from his insurance arm is lower than the interest rates that QAM’s clients get. Therefore, this is usually a benefit to Buffett relative to QAM.

QAM’s benefits:

  1. Size: Early on, Buffett focused on small companies. Given the size of his fund, he cannot practically focus on a small number of small companies, and he developed a bias towards large companies. QAM has a bias towards small companies that is likely generate a return premium relative to Buffett. This benefit is likely to be sustainable for a very long time, given QAM’s strong diversification.
  2. Country: Buffett has a bias towards American companies. QAM doesn’t have this bias, and it focuses on companies from less developed countries. This is likely to generate a return premium.
