The True Value of Macro Forecasting

While in Omaha for the Berkshire Hathaway annual meeting a couple of weeks ago, I participated in an investment panel hosted by a local chapter of the Young Presidents’ Organization. I had the privilege of sharing the stage with such industry giants as Tom Russo, a partner of Gardner Russo & Gardner (famous for knowing more about consumer stocks than the management that runs them), and Tom Gayner, president and CIO of Markel Corp., a specialty insurance company that on many levels resembles the Berkshire of 30 years ago.

We were asked how much time a value investor should spend on macro forecasting. Usually macro forecasting is frowned upon in the value investing community, and Berkshire CEO Warren Buffett has everything to do with that. He is famous for saying (and I am paraphrasing), “My decision making would not change even if I knew what the Federal Reserve will do with interest rates next month.” There is sound logic behind this: Forecasting the economy is incredibly difficult in the short run. The economy is not unlike a black box with hundreds of gauges on it that in the near term give you conflicting readings about what’s inside it.

For this reason macro forecasting was disapproved of by value investors, and for 20 years this attitude paid off. The economic climate was favorable, the stock market was in overdrive, price-earnings ratios were expanding. Macro did not matter — until the housing bubble and financial crisis. Value investors who had had their heads in the sand got annihilated.
