# Problem Set 2 helpful hints

Problem Set 2 is available from the course website at http://fin4335.garven.com/spring2021/ps2.pdf; its due date is Thursday, February 4.

Problem Set 2 consists of two problems. The first problem requires calculating expected value, standard deviation, and correlation, and using this information as inputs into determining expected returns and standard deviations for 2-asset portfolios. My one-page teaching note entitled “Mean and Variance of a Two-Asset Portfolio” (assigned reading from last Tuesday) provides simple and succinct explanations concerning how to calculate the expected return (equations 1-2) and variance (equations 3-4) of a two-asset portfolio. The second problem involves using the standard normal probability distribution to calculate the probabilities of earning various levels of return by investing in risky securities and portfolios; see pp. 17-23 of the http://fin4335.garven.com/spring2021/lecture4.pdf lecture note for coverage of that topic.
