A. Over reaction and Correction

Explanation:

In this case, the increase in price came from the announcement that the unpopular CEO had resigned. Correction on the other hand refers to the drop in prices of stock from their current peak. After the overreaction, correction occured in which the price dropped and remained constant at the dropped price.
