An investor buys three shares of XYZ at the beginning of 2002 for $100 apiece. After one year, the share price has increased to S110 and he receives a dividend per share of S4. Right after receiving the dividend, he buys two additional shares at S110. After another year, the share price has dropped to S90, but the investor still receives a dividend per share of S4. Right after receiving the dividend, he sells one share at S90. After another year, the share price has gone up to $95, the investor receives a dividend per share of S4 and sells all shares at S95 immediately after receiving dividends. 3. What are the arithmetic and geometric average time-weighted rates of return and what is the dollar-weighted rate of return of the investor in the above example (for the dollar-weighted return assume that (i) the cash flows from dividends received at the end of a given year are based on the number of shares held at the beginning of that year, and (ii) cash flows from dividends occur on the same day as the cash flows from buying and selling shares)? 4. Why is the dollar-weighted average rate of return in the above example lower than the geometric average rate of return
