Thus, a firm's manager use the split to draw attention of the investors to ensure that information about the company is recognized widely than before.
The study analysed the impact of stock splits on returns and for this purpose, the returns in the period prior to the announcement are compared with the returns after the execution of the split, in terms of mean returns and variance of returns.
Further after the splits the relative bid-ask spread increases, which lead to increase in true transaction costs.
They take quite a large sample of 1275 splits and report the excess returns of 7.93% in the first year after the splits and 12.15% in the first three years following the splits.
 The split was advisable to broaden ownership and achieve a more popular price level.
The prior research on signaling effects focuses on share price reaction around the split announcement date, but liquidity effects are best detected around the split ex date.
Our paper provides evidence that asset opaqueness problems explain, at least in part, the split ratings of non-banking firms.

We show that the number of shareholders remains the same around the split
but the number and percentage of shares owned by institutions increases.
Moreover, the order imbalances induced by the splits

However, Rozeff uses annual data and matches funds based on asset growth in the year the split
