Tap Dancing to Work: Warren Buffett on Practically Everything, 1966-2013

by Carol J. Loomis

Let’s wade through a little arithmetic about book and market value. When stocks consistently sell at book value, it’s all very simple. If a stock has a book value of $100 and also an average market value of $100, 12 percent earnings by business will produce a 12 percent return for the investor (less those frictional costs, which we’ll ignore for the moment). If the payout ratio is 50 percent, our investor will get $6 via dividends and a further $6 from the increase in the book value of the business, which will, of course, be reflected in the market value of his holdings. If the stock sold at 150 percent of book value, the picture would change. The investor would receive the same $6 cash dividend, but it would now represent only a 4 percent return on his $150 cost. The book value of the business would still increase by 6 percent (to $106) and the market value of the investor’s holdings, valued consistently at 150 percent of book value, would similarly increase by 6 percent (to $159). But the investor’s total return, i.e., from appreciation plus dividends, would be only 10 percent versus the underlying 12 percent earned by the business. When the investor buys in below book value, the process is reversed. For example, if the stock sells at 80 percent of book value, the same earnings and payout assumptions would yield 7.5 percent from dividends ($6 on an $80 price) and 6 percent from appreciation—a total return of 13.5 percent. In other words, you do better by buying at a disc...
