Answer:
the information was expected
Explanation:
The most likely reason for this to have happened would be that the information was expected. Usually stock prices react to the news on a speculative basis. When new information drops, investors tend to speculate as to what kind of news this is and how it will affect the stock price. This causes them to either buy or sell the stock which in large waves causes sudden price changes in the stock. If the information is expected then investors don't react suddenly and the prices do not move.
