Answer: The larger the percentage of stock in a portfolio, the greater the risk, but the greater the average return.
Step-by-step explanation:
Stock in general is more risky than most financial instruments but this risk is accompanied with greater returns. This is why it is generally advisable to diversify stock in a portfolio.
As already mentioned, stock is risky but rewarding. It therefore follows that the more stock is in a portfolio, the risker the portfolio but the greater the average return.
