A portfolio has a 1-day 95% VaR of $2 million. Assuming i.i.d. normal returns, what is the approximate 10-day 95% VaR?
Answer: $6.32 million
VaR scales with the square root of time, so $2M × √10 ≈ $6.32M.
Which risk measure is coherent because it satisfies subadditivity, unlike VaR?
Answer: Expected shortfall (CVaR)
Expected shortfall satisfies all four coherence axioms, including subadditivity, which VaR can violate.
A fund manager earns 12% with a standard deviation of 18% while the risk-free rate is 3%. What is the Sharpe ratio?
Answer: 0.50
Sharpe = (12% − 3%) / 18% = 0.50.
Which ratio uses only downside deviation below a minimum acceptable return in its denominator?
Answer: Sortino ratio
The Sortino ratio penalizes only harmful volatility below the target return.
Historical simulation VaR differs from parametric VaR mainly because it:
Answer: Makes no assumption about the shape of the return distribution
Historical simulation reprices the portfolio using actual past returns, so no distribution is assumed.
A stock has a beta of 1.4, the risk-free rate is 4%, and the expected market return is 9%. What is its CAPM required return?
Answer: 11.0%
Required return = 4% + 1.4 × (9% − 4%) = 11.0%.
Which type of risk can NOT be reduced by adding more securities to a well-diversified portfolio?
Answer: Systematic risk
Systematic (market) risk affects all securities and remains after diversification.
