Portfolio Management MCQ - Portfolio Management Section 2
The risk-free rate is generally the appropriate rate to use in discounting
government bonds. Although government bonds are generally default free,
their returns are certainly risky. Assuming a returns distribution has thin
tails when it does not and assuming symmetry in an asymmetric
distribution are both forms of model risk.
Securities vary highly in how liquid they are. Those with low liquidity are
those for which either the number of agents willing to invest or the amount
of capital these agents are willing to invest is limited. When markets are
stressed, these limited number of investors or small amount of capital dry
up, leading to the inability to sell the security at any price the seller feels is
reasonable. Systemic risk is the risk of failure of the entire financial system
and a much broader risk than liquidity risk. Credit risk is the risk of loss
caused by a counterparty’s or debtor’s failure to make a promised
payment.
The uncertainty about death creates two risks: mortality risk and longevity
risk. The mortality risk (risk of dying relatively young) is manifested by a
termination of the income stream generated by the person. In contrast,
longevity risk is the risk of outliving one’s financial resources.
Risks (and risk drivers) arise from fundamental factors in macro economies
and industries.
