Answer:
They will have a loss of $2000
Explanation:
The reason is that the short term investments are always valued at market value and the market value of 6000 shares that are left unsold are valued at $28 per share which is $2 lower than the $30 price paid to purchase 8000 shares.
The 2000 shares out of 8000 shares were sold at $35 which means the total gain on sale = ($35-$30) * 2000 shares = $10,000
On the other hand the market value of the 6000 shares left unsold is $28.
This means the net loss on decrease in value of the shares left unsold at the end of the year = ($30 - $28) * 6000 shares = $12,000
The net gain / (loss) = Gain on sale - Loss on decrease in Market value
The net gain / (loss) = $10,000 - $12,000 = ($2,000)
