A star rating is a backward-looking summary of past risk-adjusted returns, so it tells you how a fund behaved, not how it is built or how it may behave next. To research a fund properly, look past the rating at its mandate, its actual holdings, the consistency of its returns, its expense ratio, and who manages it. These reveal whether past performance came from a repeatable process or from conditions that may not recur.
Key takeaways
- A star rating summarises past risk-adjusted returns and is revised as performance changes, so it lags rather than predicts.
- Read the fund's mandate first: its category and objective define what it is allowed to do and what to judge it against.
- Consistency across many periods matters more than a single strong year, which can come from one lucky bet.
- The expense ratio is a certain, recurring cost, while future returns are uncertain, so a lower cost is a reliable edge.
- A manager change or a drift in holdings can make a fund's history a poor guide to its future.
What does a star rating actually measure?
A star rating condenses a Mutual Fund's past risk-adjusted returns into a single figure, usually comparing it against peers in the same category over a fixed period. It is a useful shorthand, but it is entirely backward-looking. It describes how the fund performed, and it is revised upward or downward as that record changes.
Because ratings are derived from history, they cannot tell you whether the performance came from a sound, repeatable process or from a concentrated bet that happened to pay off. Two funds with the same rating can be built very differently. The rating is a starting point for questions, not an answer on its own.
Why does the mandate come before the numbers?
Every fund has a mandate: its category, its stated objective, and the universe it is allowed to invest in. A large-cap fund, a mid-cap fund, and a Thematic Fund focused on one sector are not competing at the same game, and comparing their raw returns without reference to mandate is misleading.
Reading the mandate first tells you what risk the fund is designed to take and what benchmark it should be measured against. A fund that outperformed by quietly drifting outside its stated mandate is taking a risk its label does not advertise. Understanding what a fund is supposed to do lets you judge whether its results came from doing that job well or from straying.

How do you read holdings and consistency?
The holdings show what the fund actually owns and how concentrated it is. A portfolio spread across many positions behaves differently from one where the top few holdings dominate, and that concentration explains a great deal of a fund's risk. Reading holdings also reveals overlap: two funds you own may hold largely the same stocks, giving you less Diversification than you assume. Remember that disclosed holdings are a dated snapshot, as explained in Why fund holdings lag a month.
Consistency is about whether returns show up across many periods or cluster in one. A fund that beat its benchmark steadily across several years is showing a more repeatable pattern than one whose entire record rests on a single exceptional year. Looking at rolling returns over multiple windows, rather than a single trailing number, separates durable performance from a one-off.
Why does cost matter so much, and what is the expense ratio?
The Expense Ratio is the annual percentage a fund charges to run itself, deducted from the fund's assets before the NAV is struck. Unlike returns, which are uncertain, this cost is certain and recurring: it is charged every year regardless of how the fund performs.
Over long holding periods, a difference of even one percentage point in expense ratio compounds into a large gap in final value, because the fee is taken every year and the money it removes can no longer compound. This is why a lower-cost fund carries a reliable structural advantage over a higher-cost peer with a similar strategy. Cost is one of the few forward-looking facts about a fund you can know with certainty in advance.
Why do the manager and process matter?
A fund's record was produced by a particular manager or team following a particular process. If the manager who built that record has left, the history may no longer describe the fund you are buying. Fund houses vary in how much they depend on a single individual versus a documented, team-based process, and that distinction affects how much weight the past record deserves.
This is descriptive, not a recommendation of any fund: the aim is to understand what produced the returns, not to be told what to buy. On Artha Terminal, the mutual funds section brings the mandate, holdings, cost, and return history together, and Ask Warren can walk through what each figure means for a specific fund without recommending it. Pairing this with Metrics that matter long term helps you focus on the measures that hold up over time.
