Smart-Beta ETF
A smart-beta ETF tracks a rules-based factor or alternative-weighting index rather than a plain market-cap index, aiming to capture factor premia such as momentum, value, quality or low volatility.
Indian smart-beta ETFs follow indices like Nifty200 Momentum 30, Nifty100 Low Volatility 30 or equal-weight Nifty variants. They sit between active and passive: transparent and rules-driven like an index fund, but deliberately deviating from the broad market to pursue a factor tilt.
Because they diverge from cap-weighted benchmarks, smart-beta ETFs carry meaningful tracking error against the headline index and can underperform when their factor is out of favour. Investors should study the index methodology, rebalancing frequency, turnover and concentration before assuming the factor edge will persist net of costs.
