The Role of Stock Liquidity in Mergers and Acquisitions: Evidence from a Quasi-natural Experiment Abstract We examine how stock liquidity – of both acquirers and targets – affects acquisitions. We contend, relying on a simple model, that liquidity enhances acquirer stock value as an acquisition currency, especially when target stock is less liquid. Supportive of this acquisition-currency hypothesis: greater acquirer (lower target) liquidity increases acquisition likelihood and payment with stock, reduces acquisition premium, and improves acquirer announcement returns in equity deals. Our identification strategy relies on the exogenous variation in stock liquidity induced by changes in the composition of Russell-1000/2000 indices to establish causality. Consistent with the beneficial role of stock liquidity, firms take steps to improve stock liquidity prior to acquisitions.
