Here is where the Internet and its capacity for mass customization could play a major role. As I drove along, I realized that the Internet could deliver knowledge and advice to investors. It could meet the needs of those who wanted to create their own stock portfolios to meet their personal preferences.

  • Personally, I am also a big fan of using Price/Sales rather than Price/Earnings because Earnings can be altered by buying back shares of the company, even if done at an inopportune time.
  • Although there were more editing errors than I’ve ever seen in a book, NONE of them took away from the book’s message.
  • James O’Shaughnessy is a clear and engaging writer and his analysis should be considered by anyone creating a stock portfolio.
  • Many mutual funds with returns that beat a market index tend to have turnover as high as 100% or more (e.g., in a year’s time the stock in the fund portfolio will have been replaced by an entirely new set of stocks).

For many years, O’Shaughnessy’s book “What works on Wall Street” has been the Bible of many quantitative value investors who wanted to avoid analysing single companies and prefer an automated startegy to select stocks. Now, two mutual funds based on his “cornerstone growth” and “cornerstone value” strategies have run since the publication of the book. The value strategy has not worked, while the growth strategy has worked. My second problem is that he tests a number of strategies that should yield similar results. One of them will end up the best — the one that happened to fit the curiosities of history that are unlikely to repeat. (That’s one reason why I use a blend of value metrics when I do stock selection. I can’t tell which one will work the best.) The one that works the best just happens to be the victor of a large data-mining exercise. Also, when you test so many strategies, and possibly some that did not make it into the book, the odds that the best strategy was best due to a fluke of history rises.

Based upon the book, if we first take the stocks from the low Price to Sales category and then take only the top 10% based upon price performance over the last 12 months, the results are even better. In the book, he also found that those stocks that are in the top 10% in price performance over the last 12 months perform better than all other stocks over the time period he studied.
