How does a Stock Market Crash

A stock market crash is a process characterized by a sharp decline in stock prices in the stock market. The term most often refers to a double digit percentage loss in the stock market index, over a span of time. The overall performance of a stock market is calculated by taking into consideration the average of the top equity assets, therefore a sudden decline in these stock market indexes is technically considered as a stock market crash.

How does a Stock Market Crash
Stock market crashes are triggered by various factors, but economic and psychological factors play the most prominent role in the crash. Various factors can lead to a stock market crash, a prominent one being the investor sentiment. In a growing economy, wherein the gross domestic product is rising, consumer confidence is very high, and therefore there are more investments in the market. In such a situation, if the economy slows down considerably, or the growth rate declines and goes below the expected growth, there is panic among the investors and they start selling off their stocks. This excessive selling of stocks eventually triggers a stock market collapse.

Mob Psychology and Negative Attitude
Most of the times, the collapse is attributed with a mob mentality and negative attitude on the behalf of investors. Many a times a single event, such as a terrorist attack or a change in government, can also trigger a stock market crash. This most often happens when a single event creates panic in the market and investors, unsure about the future, start to sell off their stocks. When some of the top investors pull out of the market, owing to the particular unfortunate event, other investors follow them. As all investors are particularly interested in selling off their stocks, thus, the price of various stocks decline.

Delusive Speculations
When a particular asset is expected to gain value in the market, investors buy it with the aim of making profits in near future. As a number of investors buy this asset to make profits, there is a rise in the demand and fall in the price of that asset. This makes it appear as if the asset is going strong in the market, as a result of which more investors try to invest in stocks. This inflates the price of the asset to a price beyond its actual value, and at a particular point it reaches a level, wherein it becomes clear that the price is miscalculated, as opposed to its real value. This triggers a race to sell off the asset, and hence the price of the asset starts to fall. The panic caused by the decline in price further leads to more people selling off their assets, eventually leading to the market collapse.

What Happens When a Stock Market Crashes
As a result of a stock market crash, the economy loses a significant amount of money. The prices of the essential commodities rise, while the currency value goes down, which leads to deflation. If the trend continues for a long duration, many firms become vulnerable to bankruptcy. At this point the government has to step in, and guide the nationalized banks to reduce interest rates. Some investors cash in on the opportunity, and buy stocks at a lower price, which they eventually sell, to gain profits, when the markets become stable. If the investors confidence in the markets, as well as the underlying economy, is not restored, the stock market crash can push the economy into recession.

Basic understanding of how does a stock market crash help you be safe from financial crisis in such circumstances. So it's wise to keep yourself well updated about the developments in the stock market, and keep a proper track of your investments. Consulting a professional expert can help you to make a decent amount of money, but a consultant will never understand the importance of your money as better as you would.
