How to Evaluate a Mutual Fund Beyond Its Star Rating and Past Returns

Thursday, Mar 26, 2026

The fund had five stars. Strong three-year returns. Every screener ranked it at the top of its category. You invested. Two years later, it was in the bottom quartile and you were wondering what went wrong.

Nothing went wrong with your research. The research was just pointed at the wrong signals.

Why are star ratings and past returns unreliable evaluation criteria?

Star ratings and recent return figures share the same fundamental flaw: they are lagging indicators. They tell you what already happened. They say nothing about whether the conditions that produced those returns still exist or whether the fund's strategy remains intact.

S&P's SPIVA India Persistence Scorecard consistently shows that most top-quartile funds do not maintain their ranking across consecutive three-year periods. A fund that ranked in the top 25 percent over the last three years has roughly the same probability of ranking in any quartile over the next three years as a fund that ranked in the bottom 25 percent. Past outperformance is not a reliable predictor of future outperformance.

This does not mean past returns are irrelevant. They are one input among several. The problem is when they become the primary or only input.

Evaluating a mutual fund beyond star ratings means assessing the structural quality of the fund rather than the recent performance of its units. A structurally strong fund has a consistent and replicable investment strategy, a fund manager with a verifiable track record across full market cycles including downturns, a competitive expense ratio, and underlying holdings that reflect the stated mandate. These inputs predict long-term suitability more reliably than any three-year return figure or rating agency score.

What does fund-level evaluation actually involve?

The first layer of rigorous fund evaluation looks at the fund itself, its strategy, its manager, and its cost structure.

Strategy consistency is the most important and most overlooked criterion. A fund's stated mandate tells you what it is supposed to do. Its rolling returns, measured across multiple three-year windows rather than a single snapshot, tell you whether it has done that consistently across varied market conditions. A fund that shows strong rolling returns across five or more three-year periods, including periods of market stress, is demonstrating strategic consistency. A fund that shows strong recent returns but variable rolling returns may simply have been in the right market segment at the right time.

Fund manager track record matters most when assessed across a full market cycle, which typically spans seven to ten years and includes at least one significant downturn. A manager who has only operated in a bull market has not been tested. A manager whose strategy held up through 2020 or 2022 has a more meaningful track record than one whose returns look strong only from 2023 onward.

Expense ratio has a direct and computable impact on long-term returns. A fund with a 1.8 percent expense ratio versus a 0.9 percent expense ratio requires the higher-cost fund to outperform its cheaper equivalent by 0.9 percent every year just to produce the same net return for the investor. Over ten years, that gap compounds into a meaningful difference in final corpus. Expense ratio is one of the few inputs in fund selection that is fully known in advance and fully within the investor's control.

Evaluation criterion	What to look for	What to avoid
Rolling returns	Consistency across multiple 3-year periods	Strong single-period return with high variability
Fund manager tenure	Track record through at least one full market cycle	Manager who has only operated in bull conditions
Expense ratio	Below category average, especially for large-cap	High expense ratio without corresponding active edge
Strategy consistency	Holdings reflect stated mandate across all market conditions	Category drift, mandate changes, style inconsistency
AUM size	Large enough for stability, not so large it limits agility	Very small AUM with liquidity risk or very large mid-cap funds

Why does what a fund owns matter as much as what it returned?

Two funds can produce similar three-year returns through entirely different means. One might have done so by holding structurally strong businesses with consistent earnings growth and sound balance sheets. Another might have done so by concentrating in a sector that happened to perform strongly in that window.

The first fund's returns are more likely to be repeatable across varied conditions. The second fund's returns are more likely to revert when the sector cycle turns.

This is why evaluating the underlying holdings, not just the fund-level statistics, is a meaningful additional layer of analysis.

At Green Portfolio, we call this the Dual-Layer Selection Process. The first layer is fund-level evaluation as described above. The second layer is stock-level evaluation. GP scores every listed Indian stock across 18 parameters covering financial strength, competitive positioning, valuation, and forward growth outlook. Before a fund enters a milestone portfolio, its underlying holdings are assessed against this framework.

The question the second layer answers is: does the fund that looks strong at the category level actually own businesses that are structurally sound? A fund can have a consistent strategy and a capable manager but still hold a concentration of businesses with deteriorating fundamentals. The stock-level layer catches this before it shows up in the fund's performance numbers.

Most fund selectors, whether platforms, advisors, or rating agencies, apply only the first layer. The second is where the real signal about long-term suitability lives.

How does this apply to building a milestone-matched portfolio?

The Roadmaps Framework uses the Dual-Layer Selection Process to ensure that every fund in a milestone portfolio earns its place on both layers, not just one.

A ₹25 Lakh Start stage portfolio needs funds that will hold through volatility across a five to seven year horizon. The fund-level layer identifies candidates with consistent strategies and reasonable cost structures. The stock-level layer confirms that the businesses those funds own can support the growth posture the milestone requires.

A ₹5 Crore Scale stage portfolio needs funds that will protect capital and manage drawdown across a ten-plus year horizon. The fund-level layer identifies candidates with resilience-first mandates. The stock-level layer confirms that the holdings carry the financial strength to hold through multiple market cycles without structural deterioration.

The milestone determines what the portfolio needs. The Dual-Layer Selection Process determines which funds can deliver it.

Value vs Growth: Understanding Your Natural Investment Style covers how investment style and fund mandate interact, and what to look for when matching fund strategy to your own investing approach.

A star rating tells you which fund won a recent race. The Dual-Layer Selection Process tells you which fund is built to run a longer one.

Most investors who read this already sensed that ratings and recent returns were insufficient. The harder part is knowing what to look at instead, and having a selection process rigorous enough to act on.

This is exactly the problem The Wealth Roadmap is built to solve. Every fund in every milestone portfolio has passed both layers of the Dual-Layer Selection Process, fund-level quality and stock-level strength, before entering the portfolio. The result is a structure built to hold across market cycles, not just to look good on last year's screener. If your current fund selection process stops at star ratings, that is exactly what The Wealth Roadmap is designed to fix. See how it works: The Wealth Roadmap
