My chat with quantitative investing pioneer James O’Shaughnessy, Chairman and Chief Investment Officer of O’Shaughnessy Asset Management.
We discuss how James got into the investment business, his gradual conversion to systematic, rules-based investing and how he came to write What Works on Wall Street.
Quantitative back tests are ubiquitous in finance and investing. James offers some advice on how to back test the right way. I follow up on his advice in my better back-test checklist.
