Multi-Factor Model
A multi-factor model combines several return factors, such as value, momentum, quality and low volatility, into a single framework to score and weight securities, diversifying across drivers of return.
Indian multi-factor indices and funds blend factors so that the weakness of one is offset by the strength of another, since factors are imperfectly correlated and cycle at different times. The model assigns each stock a composite score and constructs a portfolio that targets a balanced factor exposure.
Construction choices matter: how factors are defined, standardised and combined, how often the portfolio rebalances, and how concentration and turnover are controlled. A well-built multi-factor model aims for steadier risk-adjusted returns than any single factor, underpinning many quant and smart-beta offerings.

- Factor InvestingFactor investing is the systematic targeting of securities with specific measurable characteristics, called factors, that academic research has linked to higher long-run risk-adjusted returns.
- Smart BetaSmart 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.
- Value FactorThe value factor is the tendency, documented in long-run data, for relatively cheap stocks, measured by ratios like price-to-earnings or price-to-book, to outperform expensive ones over time.
- Quality FactorThe quality factor targets companies with strong fundamentals, such as high and stable return on equity, low debt, and consistent earnings, on the basis that high-quality firms tend to outperform on a risk-adjusted basis.
