Abstract: | In an attempt to disentangle the signaling effect from the liquidity effect of stock splits, I examine the liquidity changes following the two‐for‐one split of the Nasdaq‐100 Index Tracking Stock. Since there can be no signaling with an index stock split, any difference between pre‐ and postsplit trading may be driven by liquidity but not signaling effects. I find that though the postsplit relative bid‐ask spread is higher and daily turnover is unchanged, the frequency, share volume, and dollar‐volume of small trades all increased after the split, indicating that the split improved liquidity for small trade‐sizes. |
