Answer:
Capital Loss
Step-by-step explanation:
A capital loss occurs when an investment asset decrease in value between the time of purchase and the time for selling. The loss is realized only when the asset is sold. Examples of investment assets that can lose value include stocks, mutual funds, index funds, real estate, and bonds.
A capital gain or loss is the purchase price minus selling price of an investment asset. Capital gain is when the result is positive, implying that the asset has appreciated in value. A capital gain always attracts tax. David experienced a capital loss of $3000 as the selling price was lower than the buying price ($ 4000-$1000).
