Liquidity and tick size: Does decimalization matter?
Journal of Financial Research , Volume 22 - Issue 3 p. 287- 299
The effect of the move to decimalization by the Toronto Stock Exchange, where the minimum tick size was decreased to $0.05 from $0.125, is examined. Liquidity is measured by the price impact of unexpected volume. Results show an unambiguous gain to investors. Effective spreads decrease significantly, but the price impact is unaffected. In addition, evidence indicates an increase in trading activity in absolute terms as well in relation to U.S. exchanges for cross-listed stocks. This is consistent with the observed decrease in transaction costs.
