Traditional indices like Nifty-50 and Sensex are market-cap weighted, the higher the market cap of stock, the higher will be its weightage in the index. Smart Beta strategies, also known as“factor investing” aim to outperform the index by redesigning it.Rather than the market cap of a company, this strategy assigns stock weightage based on “factors” like volatility, growth, value, and dividends. For example, Low-Risk Smart Beta small case aims to outperform the large-cap index by giving higher weightage to large-cap stocks that are less volatile. It takes advantage of the “Low-Risk Anomaly”, which is the observation that less risky stocks (i.e. low volatility stocks) tend to generate superior risk-adjusted returns. Compared to the Nifty-100, this strategy delivers higher returns for similar levels of risk which is why it’s Sharpe ratio is 1.72 approx., 50 per cent higher than that of Nifty-100.
