Do You Know Why Stock Prices Go Up And Down?

Stocks grow because more people want to buy than sell. In this case, they are offering a higher price than the currently traded shares. On the other side of the coin, stocks fell because more people were selling than buying. To sell their shares quickly, they are willing to accept a lower price.


Stock prices change every day as a result of market forces. By this, we mean that share prices change because of supply and demand. If more people want to buy a stock (demand) than sell it (supply), then the price moves up. Conversely, if more people wanted to sell a stock than buy it, there would be greater supply than demand, and the price would fall.


However, we will look at the various reasons a trader may want to buy or sell a stock.

It is possible to review the company’s financial statements and determine company costs. It said investors who took this approach were exploring the “basics” of the company. You are trying to find an undervalued stock that is trading below its “book value.” They believe that sooner or later other traders will realize that the company is paying more than the current price and will start bidding.

Other investment psychologists call this the “technical approach.” This is when traders carefully look at charts of past stock performance and look for trends they believe will repeat themselves shortly. This trader also looks at developments across the market and tries to predict their effect on individual stocks.

The stock market is a large auction that sells the properties of big companies. If some investors believe a particular company is a good investment, they are ready to raise the price. If many investors want to sell shares at the same time, supply will exceed the demand and prices will fall.


Watching the stock market can be like bouncing a ball. It goes up and down and then goes up again. This can be very frustrating for many investors who wish to continue growing. It is this instability in the market as a whole and in individual stocks that the skilled traders win. In the absence of many experiences, individual investors need proven sources of information and orientation.


Many investors (as opposed to traders) have a buy-and-hold philosophy. This will work well in an ever-growing market. Unfortunately, the stock market is not moving in a straight line. Some ups and downs frustrate this type of investor. Today many investors have become “traders” buying and selling in market fluctuations and individual stocks. These traders make money in any market – up or down!
