About OEF valuation
Adding up its 101 holdings with company data, OEF trades at 25.9 times trailing earnings and 20.9 times analysts' forward estimates, with a price-to-book ratio of 6.47 and a dividend yield of 0.98%. Its earnings yield of 3.86% is 1.46 percentage points below the 5.33% yield to maturity of the U.S. bond market (AGG).
The ten largest holdings are 51.9% of the fund and earn 47.9% of its combined profit. By sector, Healthcare is the most expensive at 40.5 times earnings and Financial Services the cheapest at 16.1. Companies that lost money over the past year are 1.3% of the covered weight.
How these figures are calculated. Each ratio treats the fund as one company: the earnings, sales and book value of every holding are added up in proportion to its weight and divided into the fund's price. In practice that is a weighted harmonic mean, so a single stock with a very high P/E cannot distort the result, and loss-making companies reduce the fund's earnings instead of being dropped. Covers 100.0% of the fund's weight (U.S.-listed stocks with company data); company figures as of October 26, 2026.
