Answer:
There is not enough information given in the question to decide what happened to the share price when the stock market opened.
Explanation:
Using P/E ratio, the ratio which is decided by market price per share/ earning per share, is one of the quick and simple ways to estimate share price.
P/E ratio of a stock is usually expected by an investor by deriving the ratio from similar firm ( similar risk firm, operating in the same industry, having similar growth prospects...). Once investor develop their expectation on P/E ratio, share price is determined by: P/E ratio x EPS.
As there is no information given on P/E ration, there is not enough information given to develop and expectation on what stock price will be given there is only information regarding EPS is available.
