To determine Eliana's capital gain or loss, we need to calculate the difference between the selling price and the purchase price of the shares.
Purchase price of 250 shares = $78 x 250 = $19,500
Selling price of 250 shares = $62 x 250 = $15,500
Capital loss = Selling price - Purchase price
Capital loss = $15,500 - $19,500
Capital loss = -$4,000
Since the result is negative, it means that Eliana incurred a capital loss of $4,000 when she sold her shares.
