This research investigates the impact of tick size reduction on stock price efficiency and execution cost. The microstructure effect of the new tick size should only impact small caps traded at Rp200 or lower, for those shares were previously traded at Rp5 tick. Using OLS and quantile regressions, we find the new tick policy significantly improves small caps price efficiency and partially reduces execution cost. The new tick size moderately reduces the mean of execution cost but does not reduce the median.
