Analysis Into The Relationship Between Stock Price And Market Efficiencies (2006)

The topic of market efficiency has been and is likely to continue to be a matter of intense debate in the investment community. In order to understand and participate in this debate, one must understand what determines the price of stocks, and its relationship with market efficiency. In theory, the fair value of stock is its present value of future cash flows (future dividend payments). However, in practice, the market price of stock is purely determined by demand and supply.

It means if investors continue buying one stock, the demand of this stock will go up, and then its price will rise, in contrast, if investors keep selling one stock, the demand for this stock decreases, then the price of the stock will fall. Therefore, a crucial question rises, what factors drive the demand and supply of certain stocks? The answer is simple, rational investors make their buying and selling decisions by collecting relevant information about stocks. Positive news or information about one stock will make investors rush to buy this stock, which increases the demand for this stock; obviously, any negative information will make investors sell this stock, this in turn, will drag the demand of this share to go down.

Therefore, a set of information plays the most important role in determining the demand and supply for stocks, which will be finally reflected by price changes of stocks. How quickly and accurately the price of shares react towards any relevant information raises the issue of market efficiency.
