Cost Matters

Research continues to show that low fees are the most important driver of a fund's future alpha. Vanguard has a nice piece describing their findings. Click here to see the article.

R-Squared and Fund Selection

R-squared is the correlation (i.e., r) of a fund to its benchmark index multiplied by itself (i.e., squared). R-squared measures how closely a fund tracks its respective index. A recent article (see here, Wall Street Journal) suggests that investors should search for actively managed funds with low R-squareds, as this suggests the manager is truly trying to add value by concentrating on specific sectors of the benchmark universe. However, doing so increases systematic risk. So, there is a tradeoff.

Control Yourself!

Sometimes we are our own worst enemies. Research shows that our brains are wired to trade stocks actively, and this often works against us. Even professional managers (such as mutual funds) have a hard time generating consistent outperformance. So, the best managers may be those that understand the psychology of investing and are able to control themselves. See the article here, Wall Street Journal. A good book on the topic is Psychology of Investing, by John Nofsinger.

Improving Alpha

Alpha is a measure of risk-adjusted performance. Positive alpha means an investment manager has generated returns in excess of what should have been earned given the level of risk taken. However, what if two funds have the same alpha--are they equally good? Well, tracking error helps to distinguish which fund might be better, as a lower tracking error might mean less risk and a more significant alpha. (See article here, Wall Street Journal.) The Information Ratio divides alpha by tracking error to provide a more comparable performance metric.
