The initial drop in CZR shares was due to the company missing its Q1 revenue targets, which typically leads to a negative short-term reaction in the stock price. However, the subsequent recovery suggests that investors may have digested the news and are focusing on other aspects of the company's performance or future outlook that could be positive. This rebound could be attributed to factors such as strong management commentary on future earnings potential, strategic plans to address the revenue shortfall, or broader market conditions favoring the stock's recovery.
