AMFI Reclassification and Micro-Cap Investing
Every six months, the Association of Mutual Funds in India (AMFI) updates its list of large-, mid-, and small-cap stocks based on their market value.
This list is important because mutual funds have rules about how much they can invest in each category.
Some people think that when a stock moves up to a higher category, it will get more investments and its price will go up.
But a study found that this doesn't always happen.
Some upgraded stocks did well, but others didn't.
Similarly, downgraded stocks sometimes did better than expected.
This shows that the market reaction depends more on the stock's own value and performance than on its category.
The study also looked at micro-cap stocks, which are very small companies.
These stocks can give high returns but are also riskier.
A mutual fund recently stopped taking new investments in its micro-cap fund, which started a discussion about how risky these small stocks are.
Overall, the study suggests that investors should not make decisions based only on the AMFI categories or micro-cap labels, but should consider other factors as well.
AMFI reclassifies stocks into large-, mid-, and small-cap categories every six months, influencing mutual fund investments.
A study of seven reclassification cycles found mixed price performance for upgraded and downgraded stocks, with no consistent pattern.
Micro-cap stocks, ranked beyond 500 by market capitalization, have seen a 10-fold increase in mutual fund investments over five years.
Micro-cap stocks offer higher returns but come with greater volatility and risk, experiencing deeper drawdowns during market corrections.
Motilal Oswal Mutual Fund paused fresh investments in its micro-cap fund in January 2026, highlighting regulatory and liquidity concerns.
