In an efficient market, information is impounded into security prices with such speed that there are no opportunities for investors to profit from publicly available information. Actually, what types of information are immediately reflected in security prices and how quickly that information is reflected determine how efficient the market actually is. The implications for us are, first, that stock prices reflect all publicly available information regarding the value of the company. This means we can implement our goal of maximization of shareholder wealth by focusing on the effect each decision should have on the stock price all else held constant. It also means that earnings manipulations through accounting changes should not result in price changes. In effect our preoccupation with cash flows is validated.

A well-developed secondary market is crucial for the functioning of primary markets because it provides liquidity, allowing investors to buy and sell securities easily. This liquidity enhances investor confidence, encouraging participation in primary markets where new securities are issued. Additionally, the secondary market helps establish fair pricing for securities, which can attract more issuers to the primary market. Overall, the interconnectedness of these markets supports efficient capital allocation within the financial system.
