I just returned home from a lecture that was purportedly given by an equity investment expert. He made some interesting and valid market observations, but also claimed an investment selection accuracy that I believe compromised his credibility. He claimed and showed a few charts that documented a positive selection accuracy in excess of 80%. If that is an accurate scorecard, he is exceptional and has powers that exceed a host of famous market experts.
Here is a Link that summarizes the performance of a huge number of famous gurus:https://www.cxoadvisory.com/gurus/
Even the best of these gurus failed to have a 70% accuracy score. The average success ratio for this elite group failed to reach a 50% score. Investing is a challenging task. Success over a reasonably large number of decisions escapes the experts and likely escapes most of us. We do need to be somewhat lucky. Good luck to all of us. We need it.
