They perform the price matching function to facilitate trade execution at a price fair to both buyers and sellers.
To make comparisons between companies, sectors and markets a little easier, there are a number of mathematical models used. The most common and often the most helpful is the P/E ratio. The Price to Earnings ratio takes the share price and is divided by the earnings per share. It is possible to calculate this using past earnings, projected future earnings and with all sorts of moving averages ;-) Therefore, this is one number that it is vital for any investor to know and understand.
D (Weak) - The stock has underperformed the universe of other funds given the level of risk in its underlying investments, resulting in a weak risk-adjusted performance.

This is usually visible on cryptocurrency only exchanges where Bitcoin is often the de-facto main exchange currency.

It would seem wise to try and understand this mass psychology or group thinking which is often referred to by investors as the madness of crowds.

Investor Protection: Along with wealthy and institutional investors, a very large number of small investors are also served by the stock market for their small amount of investments. These investors may have limited financial knowledge, and may not be fully aware of the pitfalls of investing in stocks and other listed instruments. The stock exchange must implement necessary measures to offer the necessary protection to such investors to shield them from financial loss and ensure customer trust.

Warning 2: this is serious. If you don’t believe me, just go on Reddit (r/Cryptocurrency) and look for posts of people who ask for help.
