Question 721 mean and median returns, return distribution, arithmetic and geometric averages, continuously compounding rate
Fred owns some Commonwealth Bank (CBA) shares. He has calculated CBA’s monthly returns for each month in the past 20 years using this formula:
###r_\text{t monthly}=\ln \left( \dfrac{P_t}{P_{t-1}} \right)###He then took the arithmetic average and found it to be 1% per month using this formula:
###\bar{r}_\text{monthly}= \dfrac{ \displaystyle\sum\limits_{t=1}^T{\left( r_\text{t monthly} \right)} }{T} =0.01=1\% \text{ per month}###He also found the standard deviation of these monthly returns which was 5% per month:
###\sigma_\text{monthly} = \dfrac{ \displaystyle\sum\limits_{t=1}^T{\left( \left( r_\text{t monthly} - \bar{r}_\text{monthly} \right)^2 \right)} }{T} =0.05=5\%\text{ per month}###Which of the below statements about Fred’s CBA shares is NOT correct? Assume that the past historical average return is the true population average of future expected returns.

Question 1011 winners curse
A teacher fills up a large jar with coins. The jar is auctioned among a large class of wealthy accounting students who have never studied economics or finance.
The auction is conducted in the English style, which is as an open-outcry ascending auction. This means that the winning bidder is able to bid, win and pay slightly more than the second highest bidder's private valuation, but less than their own private valuation.
The jar of coins is not allowed to be weighed by students and is filled with different-valued coins so it’s difficult to value. Therefore there is a wide distribution of bidders’ fair value estimates. Students’ bids are purely profit-driven, there is no fame to be gained by being the winner or loser.
Assume that each bidder bids up to their personal estimate of the fair value of the jar of coins without observing the number of other bidders during the auction. The winning bidder is likely to:
