When evaluating third-party research agency star ratings (e.g., 5-star or 4-star ratings) for mutual fund scheme selection, what fundamental limitation must distributors keep in mind?

[ A ]Star ratings represent legally binding guarantees of future returns issued by the Securities and Exchange Board of India.
[ B ]A 5-star rated fund is legally prohibited from ever experiencing a negative return during a market correction.
[ C ]Star ratings are quantitative assessments of past historical risk-adjusted performance and have no predictive ability regarding future scheme returns.[ CORRECT ]
[ D ]Star ratings are assigned by unitholders through mandatory SMS surveys after redeeming units.
Takeaway

Option C is correct: Star ratings are quantitative assessments of past historical risk-adjusted performance and have no predictive ability regarding future scheme returns.

Derivation
Third-party research agencies assign star ratings and performance rankings based on historical risk-adjusted metrics (such as historical Sharpe ratios and returns relative to category peers). Crucially, empirical research shows that past quarterly top performers frequently rotate and do not consistently sustain top rankings across changing market cycles. Star ratings reflect past track records and possess no predictive power over future performance. Chasing top-rated funds constantly induces high switching costs, exit loads, and tax drag. This tests scheme evaluation realism. The common error is treating star ratings as forward return promises.
Why the others fail
A — Star ratings represent legally binding guarantees of future returns issued by the Securities and Exchange Board of India.
SEBI does not issue, endorse, or guarantee third-party commercial research star ratings or scheme rankings.
B — A 5-star rated fund is legally prohibited from ever experiencing a negative return during a market correction.
All mutual fund equity investments are market-linked and 5-star funds experience market declines during broader economic corrections.
D — Star ratings are assigned by unitholders through mandatory SMS surveys after redeeming units.
Star ratings are formulated using quantitative statistical models by research analysts, not consumer SMS satisfaction polls.
