Here’s a summary of how homework for the Math Circles program works.
Students need to join their Wikispace by entering a join code (this needs be entered only once, then you are a member for the whole year). Instructors will provide join codes in the first few classes.
Read this homework guide to learn what good homework habits are.
Online tutorial schedule:
Students are encouraged to attend. Access to the online tutorial is through your Wikispace. Please check the date before each tutorial as it may change.
Alpha, Beta, Gamma & Delta tutorials are about one hour long.
Epsilon, Omega & Calculus tutorials run as Open Office Hours. The sessions will last about 1.5 hours, and students from any of the three levels can drop in and get support.

Economics 133 - HOMEWORK 3 – SOLUTIONSCHAPTER 7 QUESTIONS 1. CH.7.20 Two investment advisers are comparing performance. One averaged a 19% return and the other a 16%. However, the beta of the first adviser was 1.5, while that of the second was 1.0 a. Can you tell which adviser was a better selector of individual stocks (aside from the issue of general movements in the market? In order to determine which investor was a better selector of individual stocks we look at the abnormal return, which is the ex-post alpha; that is, the abnormal return is the difference between the actual return and that predicted by the SML. Without information about the parameters of this equation (i.e., the risk-free rate and the market rate of return) we cannot determine which investment adviser is the better selector of individual stocks. b. If the T-bill rate were 6% and the market return during the period were 14%, which adviser would be the superior stock selector? If rf = 6% and rM = 14%, then (using alpha for the abnormal return): alpha1 = 19% - [6% + 1:5(14%- 6%)] = 19% - 18% = 1% alpha2 = 16% - [6% + 1:0(14%- 6%)] = 16% - 14% = 2% Here, the second investment adviser has the larger abnormal return and thus appears to be the better selector of individual stocks. By making better predictions, the second adviser appears to have tilted his portfolio toward under-priced stocks. c. What if the T-bill rate were 3% and the market return 15% If rf = 3% and rM = 15%, then: alpha1 = 19% - [3% + 1:5(15% - 3%)] = 19% - 21% = -2% alpha2 = 16% - [3% + 1:0(15% - 3%)] = 16% - 15% = 1% Here, not only does the second investment adviser appear to be a better stock selector, but the first adviser's selections appear valueless (or worse).
