Question 36: Which of the following statements related to Efficient Market Hypothesis is NOT TRUE? A) EMH assumes that agents are rational and people do NOT overreact or underreact when faced with new information. B) Semi-strong-form efficiency implies that neither fundamental analysis nor technical analysis techniques will be able to reliably produce excess returns C) Weak form of the EMH leaves room for Fundamental Analysis. D) In P/E ratio vs Return% dataset graph, The correlation between Price-Earnings ratio, 20-year annualized returns could be used to refute the efficient market hypothesis.

Question 51: It is currently debatable whether the stock market is efficient or not (if the efficient market hypothesis is correct). How do you expect this to change in the future? A) New investors enter the market every day, I expect market efficiency to decline in the future, as there will be more noise in the market. B) Sophisticated investors and institutions still rely heavily on human decision making. I expect market efficiency to increase in the future. As more institutions adopt computer-automated and systematic trading systems, a fair-market price equilibrium should be reached in shorter time. C) The stock market is perfectly efficient, and it will remain that way. D) The stock market is entirely inefficient, and will remain that way.

Question 55: You are using Dyna-Q to learn a policy to help with trading a new mutual fund. You only have a few days to trade before you need to cash out for other reasons. To model this time constraint do you: A) Use a high alpha (learning rate) so that you learn your policy quickly. B) Use a low lambda (discount rate) because you value later rewards less. C) Use fewer hallucination cycles so that you have more time to trade. D) Use a smaller set of training data to mimic the small time frame you will have to trade.

Question 106: You have 30 candidate liquid driver symbols e.g. SPY, XLE, XLF etc. You believe there exists a linear relationship between those 30 liquid instruments' returns and an illiquid instrument's returns e.g. SNOW: r_SNOW = \Beta_SPY * r_SPY + \Beta_XLE * r_XLE + \Beta_XLF * r_XLF + \cdots. However, you believe the relationship is sparse i.e. most Betas are zero. Which of the following regression techniques would produce a sparse linear relationship? Hint: Think about how a penalty behaves when the Beta is small. A) Lasso Regression i.e. penalize the absolute value of each regressor's beta B) Ridge Regression i.e. penalize the square of each regressor's beta C) RANSAC i.e. fit a simple linear model from random subsets of

A) If increasing the breadth component by two times the current BR, the IR will increase by two times B) If increasing the breadth component by four times the current BR, the IR will increase by two times C) If increasing the information coefficient by two times the current IC, the IR will increase by four times D) If increasing the information coefficient by four times the current IC, the IR will increase by four times

Question 532: At the beginning of the crisis breakout, how can the value of mortgage subprime bonds not be affected by the demise of the housing mortgage subprime loans which are the very thing these bonds insure? A. They are independent markets and are not always correlated since those mortgage bonds especially modern ones made of layers of tranches and the derivatives such as CDOs are very complicated products. B. The mainstream investment banks are selling/unloading bonds to unsuspecting customers, and they will not de-value them until they get them off their books, which are in fact criminal activities.

answer: B

Question 533: Which of the following statements is false? A) Q-Learning is only guaranteed to converge when supplemented by methods like Dyna due to the increased computation and further exploration. B) Q-Learning is model free and does not require knowledge about the rewards function or state transition matrix. C) Using Dyna can cause Q-Learning to take more computational time to converge if hallucinating is not significantly cheaper than interactions. D) Randomness in actions can be used to force an agent to explore the environment
