This paper examines the effect of trading on earnings management under the setting of China's non-tradable share reform. The government-enforced reform converted non-tradable shares to tradable and thus enabled blockholders and insiders to reduce holdings via public trading. We find significant increases in accruals among Chinese listed companies after the reform. The impact of the reform on earnings manipulations is increasing with the potential for share trading, the degree of information asymmetry and the intensity of stock selling by insiders and blockholders. Our findings support that trading by large shareholders and insiders significantly increases earnings manipulations.

With superior information about their customers’ prospects, suppliers extend trade credit to capture future profitable business. We show that this information advantage generates significant return predictability. After controlling for major firm characteristics, firms that rely more on trade credit relative to debt financing have higher subsequent stock returns. The return predictability by trade credit is stronger among firms with lower borrowing capacity or profitability, and is more significant for firms with a higher degree of information asymmetry. Our findings suggest that trade credit extension reveals suppliers’ information that diffuses gradually across the investing public.
