If you're looking for a measure to evaluate the skill of an investment analyst or active portfolio manager, look no further than the Information Coefficient (IC). This metric is used by professionals in the industry to gauge how well someone understands and can predict future movements in securities prices.While there are other factors that come into play when making investment decisions, the IC is a good way to get a sense of whether or not an analyst or manager has the ability to generate alpha. And in today's competitive market, generating alpha is what separates the best from the rest.So if you're looking to invest with someone who has proven skills and expertise, be sure to ask about their information coefficient. It just might be one of the most important measures you use when making your decision.
