Transaction Size, Order Submission and Price Preferences Around Stock Splits

We analyse the effect of splits on stock liquidity. The results show a drop in trading volume and depth and an increase in the relative bid-ask spread. We detect a change in trading composition, with an increase in the smallest transactions, mainly on the buyer side of shares whose prices fall significantly after the split. The information asymmetry does not diminish, given that the adverse selection component of the effective spread reduces only insignificantly for the full sample. Finally there are not significant changes in the percentage of orders that provide liquidity to the market. These findings indicate that splits, despite higher transaction costs, encourage the entry of small investors attracted by the lower stock prices
