Answer:
Since the value is negative his investment resulted in a loss of $99.
Explanation:
In order to know the profit or loss margin of the investor we need to know how much was invested, for that we multiply the amount of shares he bought by the value of each share. So we have:
invested = (total shares)*(price per share) = 150*12.6
invested = $1890
He then sold all his shares for a different price, we repeat the process above to know how much he obtained from that. We have:
returned = (total shares)*(price per share) = 150*11.94 = $1791
In order to compute his profit or loss margin we subtract the value he obtained by selling the shares by the value at which they were bought. So we have:
loss = returned - invested = 1791 - 1890 = $-99
Since the value is negative his investment resulted in a loss of $99.
