Portfolio Construction Flashcards
For normally distributed portfolios, what proportion will have returns within 2 standard deviations?
95%

What are some drawbacks of MPT? (5)
- Assumes returns are normally distributed
- Doesn’t take into account charges/tax.
- ATR may not be only consideration for investor i.e. ESG.
- Past performance does not indicated future performance.
- Tricky to get good data to plot the graph.
How does the CAPM measure risk?
Via beta, thus relative to the market.
What is the expected return for a security if:
Beta = 1.3
xReturn on a Treasury Bill = 3%
xReturn on the security = 7%
3+(1.3x[7-3]) = 8.2%
What are the main assumptions of CAPM? (5)
- Borrowing and lending all takes place at the risk-free rate.
- Investors have diversified away all non-systematic risk.
- No tax or transaction costs.
- Maximising return for a given level of risk is sole incentive for all investors.
- Investors retain identical expectations of returns and standard deviations of all assets.
