What Is An Efficient Market?

Question 3: Information efficiency in the stock market is one of the most controversial topics in financial management theory and has been the subject of many scientific research over the past few decades. The combination of popularity, controversy and criticism may indicate that the concept of interaction between information and stock price is multiple. What does an effective market mean? In a highly efficient market, the value of securities share equals the value of investment (fair price), which is assessed by a professional market analyst based on a lot of information.

The answer lies in what we call "effective market". I try to avoid economic arguments, but there are some important basic concepts that I need to understand. The idea of ​​an effective market is one of them. Essentially, an effective market is that all participants in the market (everyone who buys and sells in the market) will get all the information about trading. For example, the stock market tends to be very effective. Anyone who buys and sells shares on open stock exchanges can get the same information about the company they buy and sell, and most of them will use that information to make trading decisions.

Now, I know that you said that the market is random chaos. An efficient market hypothesis is that all market information is fully distributed and priced as assets, with the final market exceeding all members. This is totally nonsense. This is the only person who believes that this is a scholar, who has never paid. Information is absolutely ubiquitous. It is asymmetrical. And even if everyone gets the same information, we do not know how to handle it. Most people simply can not handle this information correctly and can not make the right decision. They can not separate signals from noise

Although the market for goods and services seems to be effective in several points in history, it is delusive to consider market efficiency as a result. Market efficiency is a constantly changing goal and the only way to create and maintain superior business is to continue to pursue goals. When Amazon began selling books on the Internet, it greatly improved the access and convenience of purchasing books, primarily for books that are not a popular book. This revitalizes the potential demand for these games and gives Amazon Amazon's reason to purchase these games together at a low price for each book, rather than purchasing the same game at Mom and Pop Store Is found). Amazon can then pass some price concessions to buyers. These less popular games start at prices close to the true value which is a more efficient market sign.
