Expert's answer


i Efficiency of a market refers to the capability of prices to reflect all available information. Efficiency Market Hypothesis (EMH) argues that all markets are efficient, meaning there is no room of making excess profits through investing because everything is already accurately and fairly priced. Going by this, there is little hope of beating the market. However, market returns can be matched via passive index investing.

ii. The three forms of EMH are:

a. Weak Form EMH

In this form, past information is priced into securities. The securities analysis can provide information that can be used in production of returns above market averages in the short term.

b. Semi-strong Form

This form holds tha both technical and fundamental analyses cannot provide an advantage. New infonrmation is priced instantly into securities.

c. Strong Form EMH

In this form, both private and public information is priced into stocks. Consequently, no investor gains advantage over the market.

ii. NO

EMH only implies that the prices ought to be correct signals since it already has incorporated all information available.

iv. Fair value is the agreed sale price between a willing seller and buyer. The stock fair value is ususally determined by the market where the stock is traded.


Stock market is the sum aggregate of buyers and sellers who trade in stocks. For example OTC

Stock exchange is defined as the infrastructure that facilitates stock market activities such as buying and selling shares. For example NSE.
