price / earnings
MethodologyCompany-data coverageThe rest is 8% loss-making companies, which carry no P/E by the positive-earner convention; 1% bonds, cash or other non-equity.
3.3%
MethodologyEarnings yieldP/E is price over earnings; earnings yield is the reverse, earnings over price, and reads like a bond yield. P/E covers only the profitable holdings, since a loss-making company has no meaningful P/E. Earnings yield counts the loss-makers too, so it covers more of the fund and can fall below zero when the holdings lose money overall.
