When you invest in an actively managed mutual fund, you are not just buying the portfolio — you are buying the judgment of the fund manager. Yet most investors spend more time reading product brochures than evaluating the person managing their money. A fund's 5-year track record only means something if the same manager generated those returns.
Start with tenure
The most common mistake: investing in a fund based on 5-year returns when the current manager joined 18 months ago. The track record belongs to whoever was managing the fund during that period. Check the fund's factsheet or AMC website for fund manager appointment dates. Only attribute returns to the current manager for the period they have been running the fund. If the manager has been in charge for less than 3 years, the historical performance data is largely irrelevant to your investment decision.
Consistency across multiple time periods
A fund manager who outperformed in 2021 but underperformed in 2022 and 2023 may have been positioned for a specific macro tailwind, not displaying repeatable skill. Look for managers who show top-quartile or at least top-half performance across multiple rolling 3-year windows — bull years, sideways years, and bear years. Valuepresearch's fund pages show annual calendar year returns, which help identify consistency.
Performance relative to benchmark and peers
Raw returns tell you nothing without context. A 15% return in a year the Nifty Midcap 150 returned 20% is underperformance, not success. Always compare: (1) fund return vs benchmark TRI, and (2) fund return vs category average. A manager who consistently beats both over multiple cycles is adding genuine value.
Manager's other funds
Most fund managers run multiple schemes. If the manager of your mid cap fund also runs a flexi cap and a focused fund, look at all three. Consistent alpha across different mandates is a stronger signal of skill than outperformance in a single fund. Conversely, if one fund is strong and the others are average, question whether the outperformance is replicable.
AUM growth: the capacity trap
A small cap or mid cap manager who delivered 20% returns managing ₹2,000 crore faces a fundamentally different challenge managing ₹20,000 crore. At scale, it becomes impossible to build meaningful positions in smaller companies without moving the price against yourself. Track how AUM has grown — very rapid AUM increase in niche categories is a legitimate performance risk. Some of India's best small cap managers have periodically closed their funds to new SIPs for exactly this reason.
