Share market efficiency can exist in three forms, but before understanding them, you must know what market efficiency means. It is a financial tool deployed to evaluate the ability of the share market to implement the information in such a manner inviting opportunities for buyers and sellers. This is a process that impacts a transaction without hiking its costs. In essence, the share market is big and liquid in nature, and it becomes essential for this reason that investors have access to the information on costs.

Kavan Choksi – an insight into the three forms of share market efficiency 

 Business expert  Kavan Choksi  has invaluable knowledge about investments and financial management. According to him, there are three forms of market efficiency, and they are weak, semi-strong, and strong form.

Weak form

 This form of market efficiency embraces the assumption that the movement of the prices in the past does not influence the price rates in the future. In simple terms, this means that the previous price trends have no impact on how the prices in the future will trend. Due to the above assumption, the rule that some investors will buy or sell their stock is entirely invalid.

Semi-strong form

 This type of market efficiency assumes that the market stocks adjust quickly to make it absorb the latest public information to ensure that the benefits enjoyed by the investor do not exceed the market when trading is done based on this recent information.

Strong form

 This type of market efficiency assumes that private and public information is reflected in the prices currently in the market. The assumption includes the other two types of market efficiency- the weak and the semi-strong form. Based on this assumption, both private and public data are reflected in the share prices. None of the profits of the investors exceed the profits earned by the average investor, even if they have been exposed to internal private information.

How is market efficiency deployed in the share market?

 Investors who take market efficiency into account believe that, at some time, stocks can fall below the prices they are worth. Those investors who can make a successful valuation of these stocks can make profits by purchasing supplies when their prices are low and selling them off once their costs hit a high.

However, at the same time, there are investors who are uncertain about the presence of any form of market efficiency and active traders. They assert that if there are no opportunities in the market for earning profits that are lucrative, there is no point in becoming an active trader. They also believe that the fees that active managers charge are indicative of the transaction prices in the efficient market being less.

According to business and finance expert  Kavan Choksi , in order to make the market efficient, it is crucial for investors to view the market as inefficient with the objective of beating it. It is only in this manner that the share market can be efficient again. However, on close examination, you will find an irony exists that those strategies for investments supposed to take advantage of the market inefficiencies are actually those that help maintain its efficiency.
