I don’t quite agree with the solution. 12pm has the jump too, 150 - 125/125 = 20%, which is mentioned in the options and the question didnt ask for largest share, so it can be 12pm and 20%, am i right here?
No, you’re not right here.
The question says the investor chose the times that gave “
the greatest possible dollar gain per share.”
Buying at 11am and selling at 12pm gives a gain of 150 - 125 = 25 dollars per share.
Buying at 1pm and selling at 2pm gives a larger gain of 160 - 125 = 35 dollars per share.
Since 35 is greater than 25, only the 2pm/28% combination matches the scenario the question describes.
