The Price Effects of Liquidity Shocks: A Study of SEC’s Tick-Size Experiment

This paper studies the SEC’s pilot program that increased the tick size for approximately 1,200 randomly chosen stocks. We provide causal evidence of a negative impact of a larger tick size on stock prices equivalent to roughly $7 billion investor loss. We investigate direct and indirect eff ects of the tick size change on stock prices. We find that treated stocks experience a reduction in liquidity, but find no signi ficant change in liquidity risk. Test stocks experience a decline in price efficiency consistent with an increase in information risk. The evidence suggests that trading frictions aff ect the cost of capital.
