Using Value, Momentum, Quality, Size, and Volatility Factors to Compare Stocks

Article BigQuant

Summary

This overview introduces common stock-selection factors and gives formulas for valuation, momentum, quality, company size, and volatility. It describes price-to-earnings and price-to-book ratios, a twelve-month price comparison, return on equity, market capitalization, and annualizing daily return volatility. A worked comparison applies several of these measures to two hypothetical stocks and discusses how their relative readings might inform a selection decision.

The example illustrates how factor measures can point in different directions: one stock appears stronger on earnings valuation, return on equity, and volatility, while the other has a lower price-to-book ratio. The article suggests combining factor scores when constructing a diversified portfolio, but it does not specify a scoring, weighting, or rebalancing method. Its two-stock illustration is simplified and offers no backtest or evidence that the measures predict future returns; factor definitions and risk comparisons alone do not establish investment merit.

Key ideas

  • Value can be represented with price-to-earnings and price-to-book ratios.
  • A simple momentum measure compares the current price with its level twelve months earlier.
  • Return on equity is presented as a measure of business quality, while market capitalization represents company size.
  • Daily return volatility can be annualized by scaling it with the square root of the trading-day count.
  • The two-stock example illustrates factor comparison but does not validate a predictive strategy.
