This week, we cover our strategy that focuses on firms passing the AAII Neff screen. Inspired by John Neff—who served as portfolio manager of the Vanguard Windsor Fund from 1964 until his retirement in 1995—the Neff value investing approach uses a stringent contrarian viewpoint. Neff perennially found undervalued, out-of-favor stocks in the bargain basement. He liked stocks with a combination of low price-earnings (P/E) ratios, solid forecasts in earnings and sales growth, and an increasing dividend yield. Neff searched for stocks that were unattractive and, in his words, matched the fund’s “cheapo” profile. Neff’s book, “John Neff on Investing” (Wiley, 2001), discusses these value investing principles. His book served as the primary source for the construction of our screen.
In 1993, we started a real-money portfolio to show that a consistent investment approach could be followed without a significant time commitment.

John Neff was the manager of the Vanguard Windsor Fund for more than three decades. While widely considered a value and contrarian investor, Neff referred to his investing style as a low price-to-earnings (P/E) methodology. From 1964 to 1995, Neff guided Windsor to a 13.7% average annual return, easily outpacing the S&P 500's 10.6% percent return during that time. A $10,000 investment in Windsor (with dividends reinvested) at the start of Neff's tenure would have ended up as more than $564,000 by the time he retired, more than twice what the same investment in the S&P would have yielded.
