Drug approval decisions: A note on stock liquidity effects
AbstractWe analyze the relationship between positive stock returns, changes in trading activities, and liquidity improvements following drug approval announcements. Using a unique hand-collected data set on approval decisions in Europe, we find that stock liquidity does change. Stocks temporarily exhibit strong abnormal trading volume, lower spreads, and permanently become more liquid. Our results suggest that the initial positive wealth effect of a new drug release reflects both positive information content and liquidity improvements.
