Extreme Returns from Extreme Value Stocks: Enhancing the Value Premium

Abstract:     
Investigations into value-based 'anomalies' such as the P/E effect typically sort shares into quintiles, or at most deciles. These are blunt instruments. We test whether most of the extra value to be found in the lower end of the P/E spectrum is to be found in the very lowest P/E shares, and whether the worst investments are in the few shares with the highest P/E. Using a long-term definition of earnings, and attributing influences on the P/E to company size and sector, we find that small portfolios of value shares give returns of 40%+ per annum, while small portfolios of glamour shares give returns less than the risk-free rate. We thus show that by a more judicious use of the P/E ratio, we can considerably enhance the value premium.
