a single year of underperformance is rarely enough reason to exit a mutual fund. even two years may not tell the full story, particularly if market leadership is concentrated in a few stocks or sectors.
the concern arises when a fund repeatedly fails to beat the benchmark over longer periods despite charging active management fees. the decision to exit must rest on evidence. not a single return number, not one bad quarter, but meaningful and persistent signs that something has changed.
first, define underperformance correctly
lagging the market during a rally does not mean a fund is underperforming. underperformance means delivering weaker results than expected for its category, benchmark, and risk level.
comparisons need to be fair. a flexi-cap fund cannot be judged against a small-cap fund during a small-cap boom. a conservative hybrid fund cannot be compared with a pure equity fund in a bull market.
what to check
1. category-relative underperformance, not just low returns.
markets move in cycles. sometimes an entire category struggles. that is different from a single fund consistently lagging its peers.
check 3-year and 5-year returns versus the benchmark. check the fund’s category ranking over the same period. a fund that consistently ranks in the bottom quartile over 3-5 years is a concern. a one-off lag is not.
2. rolling returns, not point-to-point.
point-to-point returns can mislead. they depend heavily on start and end dates. rolling returns answer a better question: across multiple overlapping periods, how often did the fund outperform.
check 3-year rolling returns over at least 5-7 years. if the fund loses to its benchmark in most rolling periods, that suggests structural weakness, not temporary noise. a fund where 70% or more of rolling return periods beat the benchmark indicates the manager adds value consistently.
3. changes in portfolio or mandate.
sometimes the problem is not returns. it is identity. a fund may drift from its stated mandate. a large-cap fund may add mid-cap risk. a diversified fund may become concentrated. sector exposure may shift dramatically.
even if returns recover, the fund may no longer fit the role it was assigned in the portfolio. check changes in market-cap allocation, rising concentration in top holdings, and sector tilts versus the mandate. a fund that moves away from its stated style may no longer match the role it was meant to play.
4. changes in fund manager or process.
a fund’s track record is built by a team and a process. if either changes materially, the past may no longer be a reliable guide. a manager change is not an automatic sell signal. but it is a reason to review.
check whether the change is isolated or part of broader churn. check whether the fund house has altered the stated process. check whether portfolio behaviour has shifted after the change (turnover, concentration, sector bets).
5. costs, taxes, and risk-adjusted returns.
switching is not free. exit load, tax implications, and replacement quality must all be considered.
a fund’s expense ratio directly reduces returns. a fund earning 12% gross returns with a 2% expense ratio gives 10% net. the same fund with a 0.5% expense ratio gives 11.5%. over 20 years, this difference compounds significantly.
returns alone do not tell the full story. two funds may have delivered similar returns over five years, but one may have taken significantly more risk to get there. check the sharpe ratio, which measures how much return a fund generates for every unit of risk taken. a fund consistently ranking below peers on these measures may not be using risk efficiently.
how long to wait
for a good fund going through temporary underperformance, a 3-5 year runway is reasonable to check for improvement. ideally, a period covering an entire market cycle consisting of a bull phase, bear phase, and recovery phase—is a good timeframe to evaluate long-term performance.
if a fund slips from a top quartile or top-third slot, give it time to make course corrections. underperformance of 3 to 4 quarters can be tolerated to give time for an investment call or course correction to be visible in the performance. if it still does not show signs of regaining its position, switching may be advisable.
frequently asked questions
1. how long should a fund underperform before exiting?
persistent underperformance over 3-5 years, not one bad year, warrants attention. a fund that consistently lags its benchmark and peers over multiple periods may have structural issues.
2. what is rolling return and why does it matter?
rolling returns measure performance across multiple overlapping periods. they show how often a fund beat its benchmark, removing the bias of a single start and end date.
3. what is style drift and why should it be checked?
style drift occurs when a fund moves away from its stated mandate. a large-cap fund holding mid-cap stocks or a value fund shifting to growth stocks changes the risk profile of the portfolio without the investor’s consent.
4. does a fund manager change mean immediate exit?
no. a manager change is a reason to review, not an automatic sell signal. check whether the investment approach and portfolio construction change after the change.
5. what are the costs of switching funds?
exit load, capital gains tax, and the opportunity cost of being out of the market. frequent switching can turn a long-term plan into a series of taxable events.
