Invest Like the Best

James O'Shaughnessy

Invest Like The Best - James O'ShaughnessyInvest Like The Best praises a similar investment approach to that of What Works On Wall Street: that is an investor is best using a mechanical and unemotional investment strategy.

O'Shaughnessy explains that the determinants of a portfolio returns are its main factors (Market Capitalization, Valuation, Growth Rates, Relative Strength,...) rather than its specific stocks holding

That is 2 portfolios with similar Market Capitalization, PE, Growth, Relative Strength... will have similar returns over time even though they contain different stocks.

The book then shows how to analyze successful Gurus' Portfolios to extract their main factors so that you can build a stock screening that mimic their strategy.

Provided your portfolio exhibits similar factors to that of your favorite gurus or Mutual Fund managers, your performances shall more or less match theirs over time.

The book features many different successful Fund Managers and Gurus to give you a broad choice of strategies.

What is missing in the Book is the Selling part. You may use the following guidelines to choose an appropriate holding period.

Identify the primary theme (see Stock Screening):
  • If the primary theme is Value or Growth At Reasonable Price GARP, it should have holding period ≥ 1 year.
  • If it is Growth/Momentum, it should have holding period ≤ 1 year.
