Berkshire Hathaway’s performance vs S&P 500

Data source: Berkshire Hathaway 2014 Annual Report

Excerpt from Warren Buffett’s letter dated February 27, 2015, to Berkshire Hathaway’s shareholders for FY2014:

“Berkshire’s gain in net worth during 2014 was $18.3 billion, which increased the per-share book value of both our Class A and Class B stock by 8.3%. Over the last 50 years (that is, since present management took over), per-share book value has grown from $19 to $146,186, a rate of 19.4% compounded annually.* During our tenure, we have consistently compared the yearly performance of the S&P 500 to the change in Berkshire’s per-share book value. We’ve done that because book value has been a crude, but useful, tracking device for the number that really counts: intrinsic business value. In our early decades, the relationship between book value and intrinsic value was much closer than it is now. That was true because Berkshire’s assets were then largely securities whose values were continuously restated to reflect their current market prices. In Wall Street parlance, most of the assets involved in the calculation of book value were “marked to market.” Today, our emphasis has shifted in a major way to owning and operating large businesses. Many of these are worth far more than their cost-based carrying value. But that amount is never revalued upward no matter how much the value of these companies has increased. Consequently, the gap between Berkshire’s intrinsic value and its book value has materially widened. With that in mind, we have added a new set of data – the historical record of Berkshire’s stock price – to the performance table on the facing page. Market prices, let me stress, have their limitations in the short term. Monthly or yearly movements of stocks are often erratic and not indicative of changes in intrinsic value. Over time, however, stock prices and intrinsic value almost invariably converge. Charlie Munger, Berkshire Vice Chairman and my partner, and I believe that has been true at Berkshire: In our view, the increase in Berkshire’s per-share intrinsic value over the past 50 years is roughly equal to the 1,826,163% gain in market price of the company’s shares.”
