Lets assume we consider data on a groups of companies of similar investment risk. It was stated in class that under the weak form of EMH, the movement of price of a stock i is a random walk: where is the same for all stocks in the group and is independent of, and cannot be predicted by, past prices.
Consider the following equation: where is the same across the group and and is independent of past prices. Which equation you think reflects the Weak Form EMH better? Explain briefly.
Hi, See the solution in attached file. Hope this will help. Thanks.

Solution Summary
Weak Form EMH is discussed. The investment risks for companies are discussed.
This is one of six different sets of questions I need assistance with. Please see attachment. The questions are efficient capital markets and efficient market hypothesis, amongst other things.
1. What is EMH?
2. How EMH impacts investment in securities?
3. How EMH impacts on corporate decisions?
4. Is, EMH, aplicable to real assets such as plant and equipment?
a. The Capital Asset Pricing Model (CAPM) is a widely used concept in finance. The Model is
expressed graphically by the Security Market Line (SML). Within the context of investment,
explain how CAPM can be useful to investors.
b. Explain Efficient Market Hypothesis (EMH) and the different types of market efficiency.

For each of the following scenarios, discuss whether profit opportunities exist from trading in the stock of the firm under the conditions that (1) the market is not weakform efficient, (2) the market is weakform but not semistrong form efficient, (3) the market is semistrong form but not strong form efficient, and (4) the mar
It was stated that under Weak-FormEMH you cannot design an investment strategy which "beats the market" (gives you higher return than average market
return, given the riskiness), if such a strategy is based only on analyzing past price movements. Is it possible to design an investment strategy, based on past price movements, w
1. A stock market analyst is able to identify mispriced stocks by comparing the average price for the last 10 days to the average price for the last 60 days. If this is true, what do you know about the market?
2. What are the implications of the efficient market hypothesis for investors who buy and sell stocks in an attempt
Which is correct?
If a market is weak-form efficient, this implies that all public information is rapidly incorporated into market prices.
If a market is strong-form efficient, this implies that the returns on a firms's bonds and stocks should be identical.

(a) 1:1
(b) 1:10
(c) 10:1
(d) 1:3
(e) Which form of ascorbic acid predominates at physiological pH?
