Do Not Always Chase Last Year’s Best Mutual Fund: Strategies for Independent Investing

Investors and financial media routinely treat last year’s best-performing mutual fund as a signal of manager skill that is worth following, yet the academic evidence on whether past rank predicts future rank is decidedly mixed. This paper addresses that gap directly: is it profitable to invest in the best-performing large-cap mutual fund identified from the previous year’s annual report, or does a different rank position offer a more reliable combination of return and risk? This paper analyzes ten large-cap mutual funds in each of four categories—growth, income, value, and balanced—over 22 years (2003–2024). The ten funds per category are the strongest full-sample performers against the S&P 500 benchmark, identified via a cumulative-sum (CUSUM) screen, so the sample reflects a curated set of long-run outperformers rather than the broader fund universe. Within this sample, we test whether chasing the single best-performing fund from the prior year is effective and identify which past-performance rank, if any, best predicts strong subsequent results. The findings are mixed but instructive: in two of the four categories (income and balanced), a mid-ranked fund—rather than the top-ranked fund—delivers the strongest cumulative returns over the following year, while top-ranked funds show greater volatility and a tendency toward mean reversion. Growth and value are exceptions, where the top-ranked fund and a rotation strategy built on it remain the strongest long-term performers. Across three of the four categories (growth, income, and balanced), the reported average maximum drawdown figures worsen as a fund’s prior-year rank falls, a directional pattern that is broadly consistent across categories; in value, this relationship is present but much weaker, and the single worst average drawdown occurs at a middle-to-low rank rather than the very bottom. The lowest-ranked funds in every category show weak and inconsistent recovery relative to their mid-ranked peers. When mutual funds and rotation strategies in all four categories are compared against passive buy-and-hold of a matched benchmark index, the benchmark outperforms every active strategy that is considered in three of the four categories—growth, income, and balanced—often by a wide margin; value is a narrow exception, where the strongest rotation strategy edges out its benchmark by only about two percent in cumulative terminal value over the full sample. For investors who are choosing among funds with an established long-run record, the takeaway is that a fund’s rank last year is a poor guide to next year’s winner: the best- and worst-ranked funds are, on average, less reliable than funds in the middle of the pack, with growth and value again the notable exceptions.
