Why fund manager tenure matters

Tenure is the length of time the current manager has actually been running a fund — and it is one of the most overlooked numbers in fund research. Return tables tell you what the fund did; tenure tells you who deserves the credit.

The misleading 10-year record

Suppose a mid-cap fund shows a superb 17% ten-year CAGR, but its celebrated manager left two years ago and a successor took over. Eight of those ten years belong to someone who no longer picks the stocks. The number on the factsheet is real, but it describes a fund that, in a practical sense, no longer exists. Always line up the "managing since" date with the return window you are judging.

A quick ₹ illustration

Two investors each put ₹10 lakh into that fund. One checked tenure, saw the change, and judged the new manager on their two-year record and their history at other schemes. The other trusted the 10-year CAGR blindly. If the new manager's real ability is closer to 12% than 17%, the second investor's 10-year expectation is overstated by roughly ₹18 lakh of imagined future corpus (₹10L at 17% ≈ ₹48L vs at 12% ≈ ₹31L). Tenure is the difference between an informed forecast and a hopeful one.

How to read tenure well

• Long tenure + steady results is the gold standard: it suggests a repeatable process, not a lucky patch.
• Short tenure is not automatically bad. Judge a new manager on the window that is genuinely theirs, plus their record on funds they ran before.
• Co-managed funds: check which named manager actually drives the strategy and how long each has been aboard.
• Compare like with like: a 3-year manager should be compared with peers over the same 3 years, not with decade-long veterans.

Common mistakes

Investors often exit a good fund simply because it is "only" three years old under the current manager, or stay in a deteriorating one out of loyalty to a departed name. Both errors come from reading the fund's history as if it were one continuous story. Treat every manager change as a chapter break, and weigh rolling returns within each chapter.

The takeaway: before trusting any long-term number, ask one question — was the current manager there for it? Past performance, whoever produced it, does not guarantee future results.
