The investor experienced a loss on this transaction.
To calculate the loss:
Initial cost per share = 25 2/8 = 25.25
Final selling price per share = 18 3/4 = 18.75
Loss per share = Initial cost per share - Final selling price per share
= 25.25 - 18.75
= 6.50
Therefore, the investor experienced a loss of $6.50 per share.
If the investor bought and sold multiple shares, the total loss would be:
Total loss = Loss per share * Number of shares sold
