We examine the effect of illiquidity discount on stock prices on the warrants prices in China. We construct measures of liquidity based on market microstructure models, and find that they explain a significant portion of the cross-section variation in the warrants pricing biases and implied stock discounts in the market. We conclude that, due to the T+1 rule in Chinese stock market, equity market is illiquid relative to the warrants market that doesn’t bear the T+1 rule. This imposed illiquidity cause the discount on the stock price, which is not reflected in the warrants market. Thus the illiquidity in stock market contributes to the pricing bias in warrants market.
