Definition
Smart Beta
Smart beta refers to rules-based index strategies that weight securities by factors or alternative metrics rather than by market capitalisation, aiming to improve returns or reduce risk versus a plain cap-weighted index.
Indian smart-beta products track factor indices such as Nifty 200 Momentum 30, Nifty100 Low Volatility 30, Nifty Alpha 50 or equal-weight indices, packaged as smart-beta ETFs and index funds. They sit between active and passive, applying transparent rules to tilt toward value, momentum, quality, low volatility or equal weighting.
Because smart-beta indices deviate from the broad market, they carry tracking error against the headline index and can underperform for long stretches when their factor is out of favour. Investors should understand the methodology, rebalancing frequency and concentration before assuming smart beta is a free lunch over cap-weighted indexing.
