The Beardstown Ladies claimed that their stock picks gave them a 23.9 percent return from 1985-1995, when their first book came out. This was better than the 14.9 percent return of the S&P index. However, they made a mistake in their calculations and were including the investment club dues in their profits. The true investment return was 9.1 percent.

I don't think anyone has ever claimed that the Ladies were out to deceive anyone. They merely computed their results, perhaps by hand, rather clumsily using the best information they had, and arrived at the figure mentioned. Those able were still called upon to mentor other investment clubs and give lectures, even after the corrected results were revealed. The article should indicate this when someone runs across a ref.
