How to Actually Read a Mutual Fund Factsheet

Most investors glance at a mutual fund's star rating and recent one-year return, and stop there. Both numbers are backward-looking and neither says much about how the fund is likely to behave going forward, which is really the question that matters.

Expense ratio is the first number worth checking properly. It is deducted from returns every single year regardless of performance, and a difference of even half a percentage point compounds into a meaningfully different outcome over a long holding period.

Standard deviation and beta together tell you how much the fund moves relative to its own history and its benchmark. A fund with high standard deviation is not necessarily bad, but it does mean the investor needs a stomach for larger swings along the way, and a mismatch between fund volatility and investor temperament is one of the most common reasons people sell at the wrong time.

Portfolio turnover ratio reveals how actively the fund manager trades. A very high turnover ratio often means higher transaction costs eating into returns, and can also signal a strategy that is more tactical than the fund's stated long-term mandate suggests.

Finally, look at the fund manager's tenure and the consistency of the stated investment strategy over time. A fund that has changed managers or drifted from its original mandate in the last year deserves more scrutiny than its historical track record alone would suggest, since that track record was built under different stewardship.
