Common Information

Abdul, Bikram and Chetan are three professional traders who trade in shares of a company XYZ Ltd.

Abdul follows the strategy of buying at the opening of the day at 10 am and selling the whole lot at the close of the day at 3 pm.

Bikram follows the strategy of buying at hourly intervals: 10 am , 11 am, 12 noon, 1 pm and 2 pm, and selling the whole lot at the close of the day. Further, he buys an equal number of shares in each purchase.

Chetan follows a similar pattern as Bikram but his strategy is somewhat different. Chetan’s total investment amount is divided equally among his purchases.

The profit or loss made by each investor is the difference between the sale value at the close of the day less the investment in purchase.

The “return” for each investor is defined as the ratio of the profit or loss to the investment amount expressed as a percentage.

 Hide Ans

Solution:
Option(E) is correct

From the explanation seen till now we can rule out options 1, 3 and 4.

Now, option 2 is only partially correct. We have seen that Chetan’s return would be higher than or equal to that of Bikram. It would be equal to Bikram’s return in the scenario when the share price remains at a constant value throughout the day.

$\therefore$ Option 2 is not always true.

Hence, option E.
