Answer:
Price of the stock will rise or increase
Step-by-step explanation:
Efficient market hypothesis states that price of stock factors in all information related to the stock. As such, nobody can take advantage of higher returns offered by a particular stock for a long time.
In line with efficient market efficiency, if public expected a bigger loss of $5 but loss was only for $4, the price of stock will increase. Though the company still suffers a loss, it is less than what was expected by the market, resulting in increase in stock price.
