Motilal Oswal BSE Financials ex Bank 30 Index Fund Regular Growth

Motilal Oswal BSE Financials ex Bank 30 Index Fund Regular Growth ranks among the stronger performers in the Index Funds category, backed by a 4-star rating. Consistent 3-year performance combined with a strong rating makes this one of the more credible options in its space. TopFund's composite Health Score, which weighs rating, 3-year CAGR, expense ratio and fund size, puts it at 83/100.

Cost: At 0.48%, the expense ratio runs 20% above the Index Funds category average of 0.4%. That gap is worth weighing against the fund's actual performance versus cheaper peers before committing to a long SIP.

Risk-adjusted performance: Over the trailing 1-year period, the fund shows a negative Sharpe ratio of -0.07 — over the past year, returns haven't kept pace with the volatility involved, even before accounting for the risk-free rate. Separately, with 20.15% annualised volatility, this is among the more turbulent funds in its space — expect sharp swings in both directions.

Who should invest: This fund is best suited to cost-conscious investors happy to simply match the market rather than try to beat it. The High risk rating means near-term volatility should be expected — this isn't a fund to check daily.
