1. (True or false) Suppose I invested $10,000 in stock A 20 years ago and held that investment (reinvesting dividends, if any) until today.

Short-selling allows investors to benefit from price declines. 3. (True or false). Suppose I hold a portfolio of two assets A and B. 40% of my money is invested in A and the remaining 60% is invested in B. Suppose the risks (return volatility) of A and B are both 10%. Then, the volatility of my portfolio return will also be 10%. 1
