Recently many scholars divide stocks into value and glamour stocks according to ratios of stock price and accounting data, and examine if there is difference between returns of two types. Their results show that value stocks outperform glamour stocks, and investment in value stocks is called value strategies. These value strategies call for buying stocks that have low prices relative to earnings, book value and sales. Value strategies means to invest in undervalued stocks, but not all the stocks with low ratio are undervalued stocks, it could be distress stock. In this article, I try to enhance value strategies through four aspects, including two value factors, operating side, financial structure side and market liquidity side. My results show that traditional value strategies succeed in all stocks and large stocks, but fail in small atocks. Besides, for enhanced value strategies, enhancement through financial structure side and market liquidity side can improve performance of traditional value strategies.
