Answer: The average Sharpe ratio of hedge funds is overstated and the average Sharpe ratio of real estate funds is also overstated.

## Explanation **Hedge Fund Bias (Survivorship Bias):** - When hedge funds stop reporting due to poor performance and are removed from the database, this creates **survivorship bias** - Only the better-performing funds remain in the database - This leads to **overstated average performance** and **understated average volatility** for hedge funds - Since Sharpe ratio = (Return - Risk-free rate) / Volatility, both higher returns and lower volatility contribute to a **higher Sharpe ratio** **Real Estate Fund Bias (Infrequent Trading/Stale Pricing):** - Infrequent valuation (only once per year) creates **smoothing** in reported returns - This smoothing artificially **reduces measured volatility** - With lower volatility and similar returns, the **Sharpe ratio becomes overstated** **Combined Impact:** - Hedge funds: Overstated Sharpe ratio due to survivorship bias - Real estate funds: Overstated Sharpe ratio due to infrequent trading/smoothing - Therefore, both Sharpe ratios are overstated **Why other options are incorrect:** - **A**: Incorrect because hedge fund Sharpe ratio is overstated, not understated - **C**: Incorrect because hedge fund volatility is understated, not overstated - **D**: Incorrect because real estate fund volatility is understated, not overstated
