Over the last 10 years, a portfolio of industrial bonds has mean annual returns of 15% with a standard deviation of 30%. During that same time period, a portfolio of T-bills earned 5% per year, on average. What where the industrial bond’s annual risk premium over the last ten years?

What is the optimal capital allocation for a client with quadratic utility and a risk aversion index of 5 if their potential risky portfolio has a risk premium of 9% and a standard deviation 26% while the risk-free rate is 4%?

From 2010 to 2024, the average and standard deviation of the monthly percentage changes in the S&P 500 are, approximately, 1 percent and 4 percent, respectively. What is the annualized standard deviation (hint: use the APR approach)?

A client of yours has $[C0]0,000 to invest. Their goal is to earn as high a rate of return as possible, but wants to limit the risk of their complete portfolio to [SDc0]%. Their risky portfolio, which you believe has the highest possible Sharpe ratio, is invested equally (i.e., 25%) in U.S. stocks, international stocks, bonds, and commodities. That portfolio has a risk premium of [ERp0]% and a standard deviation of [SDp0]%, respectively. How much of their capital should you allocate to the risk-free asset, which currently yields 4%? Enter your answer as a number of dollars, rounded to the nearest dollar. E.g., for $12,345.6789, enter 12,346.

Your fund’s risky portfolio has an expected return of 12% and a standard deviation of 19%. The risk-free rate is 4%. Based on your advice, your client goes with a risky portfolio allocation of 75%. What is the expected return on their complete portfolio?

This quiz is based on the same data used in Lab 2, that is, you are given the following database schema (with primary keys underlined):    PEAK(NAME, ELEV, DIFF, MAP, REGION)    CLIMBER(NAME, SEX)    PARTICIPATED(TRIP_ID, NAME)    CLIMBED(TRIP_ID, PEAK, WHEN_CLIMBED)The database tables have the following semantics (which is the same as in Lab 2):    1. PEAK gives information about the mountain peaks that the SPCC is interested in. This table lists the name of each peak, its elevation, its difficulty level for climbers (on a scale of 1 to 5), the map that it is located on, and the region of the Sierra Nevada that it is located in.    2. CLIMBER lists the SPCC membership, and gives their name and gender.    3. PARTICPATED gives the set of climbers who participated in each of the various SPCC-sponsored climbing trips. The number of participants in each trip varies.    4. CLIMBED tells which peaks were climbed on each of the SPCC-sponsored climbing trips, along with the date that each peak was climbed. Note: To make sure you are using the correct original data file, please download the Lab 2 data “climbers.db” again before you start answering the questions. The data file is in lab_2_setup.zip, click this link (lab_2_setup.zip) to download it directly. DO NOT leave this quiz to download it from other pages, since you can only attempt once for this quiz.   For all the following questions in this quiz, you need to make up the SQL queries, run them in SQLite, and select the correct choice.

The region of the first peak, mainly sorted by their difficulty levels in descending order, then sorted by the elevations in ascending order in thecase that difficulty levels are the same.
