In developing markets, new regulations are imposed to protect investors, to assure fairness and to enhance trust through controlling all types of market abuse. In addition, these regulations are imposed to enhance the overall market performance and efficiency. Market liquidity is one of the main pillars used to measure market overall performance. In this paper, the authors attempt to analyze market liquidity before and after the passage of the Capital Market Authority Law of 2010 (CMA), aimed at enhancing investors’ confidence and reinforcing better disclosure quality and accountability for Kuwait public companies. By introducing six liquidity measures that captures market depth, turnover, and volatility, the authors documented highly significant deterioration in all the measures following the CMA Law with more profound effect on smaller firms. The researchers concluded that overstated regulations in developing markets, in spite of its goal of improving market overall performance, structure, enhancing investors’ protection, and market integrity, can have an adverse effect on market efficiency.
