For example, if a portfolio’s 1-day VaR is $1 million at a 95% confidence level, you don’t know how much the loss could be in the remaining 5% of the cases. This means that it doesn't account for "tail risk" or extreme events that may lead to larger losses. This brings us ...
Example cont’d: Now we can compute the marginal VaRs for each asset within the portfolio. First, we compute betas by (3.2.4)Image 3.2.1 Correspondingly marginal VaRs are computed by (3.2.3 b) These quantities are interpreted as a change in portfolio VaR as a result of an additional dol...
The manager has inadvertently created an active position on some factor that contributes significantly to marginal active risk. For example, a manager who builds a portfolio by screening on yeild will have a large incidental bet on industries that have higher than average yields. Are these industry...

For example, if the expected return of a market portfolio is 12%, risk free rate is 4%, and a stock has a beta of 1.2, its expected return is 4% + 1.2 x (12% ? 4%) = 13.6% ORBS 7220 8 2012/13 Summer Term, Lecture 9 Using the CAPM: example ? rM=12%, rf=7%, ?M=32...

from different asset classes, industries, and regions to spread risk without sacrificing expected return. In general, a more aggressive risk tolerance will feature a greater allocation to stocks, while a more conservative portfolio will hold relatively more bonds and cash (see the example Figures ...
Some risks are resistant to diversification tactics and they represent a different challenge for an investor managing portfolio risk. These risks are known as market risks, or systematic risks, and they can sweep through an entire market or segment of the market. For example, an economy in reces...
For example, a portfolio that starts with a 70% equity and 30% fixed-income allocation could, after an extended market rally, shift to an 80/20 allocation. Investors have made a good profit, but the portfolio now has more risk than investors with that balance can tolerate. ...
Does your risk tolerance still match your goals? For example, a more conservative stance—such as shifting from stocks into bonds and other fixed income investments—makes sense the closer you get to retirement. Indeed, those in or near retirement may want to keep enough cash on hand to cover...
