Answer:

The portfolio SD is A. 20.65%

Explanation:

The standard deviation tells the total risk (both systematic and unsystematic) associated with a stock or a portfolio. The portfolio risk or the standard deviation of portfolio can be calculated using the following formula as attached in the picture below.

Using this formula, the standard deviation of the portfolio is:

SDp = √(0.3)² * (0.2)² + (0.7)² * (0.25)² + 2 * (0.3)*(0.7) * 0.4 * (0.2)*(0.25)

Portfolio SD = 0.20645 or 20.645% rounded off to 20.65%

g For this question, ignore inflation. Suppose Jenny earns $60,000 per year working as a tax analyst. After ten years, she quits
arsen [322]

Answer:

If Jenny doesn’t earn any interest on her savings and wants to perfectly smooth consumption across her life, how much will she consume every year?

Jenny's total income during her life = income as tax analyst ($60,000 x 10) + income as PhD student ($12,000 x 5) + income as Art Director (35 x $95,000) = $3,985,000

she generated income during 50 years and expects to live 20 more, so in order to perfectly smooth consumption across her life, she must divide her total life income by 70 years = $3,985,000 / 70 years = $56,928.57 per year

What might prevent her from perfectly smoothing consumption?

First of all, besides inflation, you also earn interest on your savings. That is why 401k and other retirement accounts work so well (the magic of compound interest). Even if inflation and interests didn't exist, you cannot know exactly what you are going to earn in the future and for how many years. In this case, she earned $60,000 for 10 years, but then earned only $12,000 during 5 years. If she really wanted to smooth her consumption, she would have needed to get a loan because her savings during the first 10 years wouldn't be enough.
