Which of the following statements on the forms of the efficient market hypothesis (EMH) is least accurate?
A)
The semi-strong form EMH addresses market and non-market public information.
B)
The strong-form EMH assumes perfect markets.
C)
The weak-form EMH states that stock prices reflect current public market information and expectations.
The weak-form EMH assumes the price of a security reflects all currently available historical information. Thus, the past price and volume of trading has no relationship with the future, hence technical analysis is not useful in achieving superior returns.
The other statements are true. The strong-form EMH states that stock prices reflect all types of information: market, non-public market, and private. No group has monopolistic access to relevant information; thus no group can achieve excess returns. For these assumptions to hold, the strong-form assumes perfect markets – information is free and available to all.
The statement, "Stock prices fully reflect all information from public and private sources," can be attributed to which form of the efficient market hypothesis (EMH)?
A)
Semistrong-form EMH.
B)
Weak-form EMH.
C)
Strong-form EMH.
This is the definition of the strong-form EMH. Private sources include insider information, such as persons holding monopolistic access to information relevant to the formation of prices.
Which of the following statements about market efficiency is least accurate?
A)
The weak-form EMH suggests that fundamental analysis will not provide excess returns while the semi-strong form suggests that technical analysis cannot achieve excess returns.
B)
The strong-form EMH assumes cost free availability of all information, both public and private.
C)
The semi-strong form EMH addresses market and non-market public information.
The weak-form EMH suggests that technical analysis will not provide excess returns while the semi-strong form suggests that fundamental analysis cannot achieve excess returns. The weak-form EMH assumes the price of a security reflects all currently available historical information. Thus, the past price and volume of trading has no relationship with the future, hence technical analysis is not useful in achieving superior returns.
The other choices are correct. The strong-form EMH states that stock prices reflect all types of information: market, non-public market, and private. No group has monopolistic access to relevant information; thus no group can achieve excess returns. For these assumptions to hold, the strong-form assumes perfect markets – information is free and available to all.
Which of the following forms of the EMH assumes that no group of investors has monopolistic access to relevant information?
A)
Strong-form.
B)
Both weak and semistrong form.
C)
Weak-form.
The strong-form EMH assumes that stock prices fully reflect all information from public and private sources. In addition, no group of investors has monopolistic access to information relevant to the formation of prices.
The semi-strong form of the efficient market hypothesis (EMH) asserts that stock prices:
A)
fully reflect all historical price information.
B)
fully reflect all relevant information including insider information.
C)
fully reflect all publicly available information.
The semi-strong form of the EMH asserts that security prices fully reflect all publicly available information. This would include all historical information. The weak form relates to historical information only. The strong form relates to public and private information.
