Smart Beta

Smart Beta refers to rules-based, transparent index strategies that deviate from market-cap weighting to tilt toward documented return factors — value, momentum, quality, low-volatility, or size. The promise: capture factor premia at near-passive cost.

How it works: Each factor strategy follows a published rulebook (e.g., Nifty 200 Momentum 30 picks top-30 momentum stocks from Nifty 200, rebalanced semi-annually). The fund/ETF tracks the resulting index. TER usually 0.30-0.60% — higher than a Nifty 50 fund but a fraction of active management cost.

Example: Nifty 200 Momentum 30 index returned 24.5% CAGR over 5 years to Mar 2025 versus Nifty 200 at 16.8% — a meaningful factor premium. But the same strategy lagged the broad index for 18 months during the 2022 momentum drawdown.

When to use: Satellite allocation around a core index fund, or as a low-cost alternative to active equity managers who claim to deliver factor exposure.

When NOT to use: As a "set and forget" core holding — single-factor strategies go through multi-year cold streaks. Need patience and ideally multi-factor diversification.

Caveat: Past performance is not indicative of future returns. Factor premia are not free — they come with periods of severe underperformance.
