This study investigates the liquidity effects of reverse stock splits
using bid-ask spread, trading volume, and the number of nontrading day
s as proxies for the liquidity of the stock. Results indicate a decrea
se in bid-ask spread and an increase in trading volume after reverse s
plits. More importantly, the number of nontrading days significantly d
eclines following reverse splits. For the control group, however, no s
uch changes are observed. These results suggest that reverse splits en
hance the liquidity of the stock.
