Answer:
D) The investor can expect income from the premiums received when selling the covered calls.
Step-by-step explanation:
When an investor sells covered calls, but believes that the market will remain very stable, he/she is making money by selling the calls since they shouldn't be used. By selling the calls the investor is not gaining leverage and probably will end up not selling the stocks.
If the stock prices decrease, the options will expire and if the price increases, the investor would end up selling the stock and maybe even losing money. But the key factor is that the stock price should remain stable, therefore the investor earning from selling something he/she believes is useless to other investors.
