Factor Name: Price-to-Book Ratio (PB) - Factor Construction Idea: This factor is based on the valuation metric of price-to-book ratio, aiming to identify stocks trading below their book value. [16] - Factor Construction Process: The factor is calculated as the market price of a stock divided by its book value per share. - Factor Evaluation: The factor showed positive performance, particularly in the liquidity 1500 stock pool.
