The companies which sell this type of stock are in serious financial difficulties, and this makes their stocks high risk, because there is a significant risk of that company being declared bankrupt. The value of these penny stocks can change enormously over a very short time span, usually decreasing, but in some cases the value does rise.

Why do people invest in penny stocks if they are this risky? Although this investment is very unpredictable, some people believe that they can get a quick return for their investment in this way, and because they are available at such a low purchase price, investors can buy a large number of them. For example, an investor buys penny stocks at $0.10 each, and invests $1000, for which he receives 10,000 shares. If the value of these stocks rises to $0.25 each, and he sells at that price, he has made a quick profit of $2,500.

If you are considering investing in penny stocks in the stock market, see if you can find companies which are likely to have a good future. Perhaps they are about to expand, which could mean they are likely to improve their share value.

If a company which is new on the stock market is offering penny shares, then they are worth considering. Microsoft, for example, offered penny stocks for $2.50 each when they were new on the market. This is an unusual example, however, because not all companies are bound to have such huge success, and you may need to look deeper into the company itself before investing in a new one which is offering penny stocks.

Remember always that penny stocks are high risk investments, and therefore there is a high likelihood that you could lose money when you buy them. The information which you obtain on the companies which are offering them is unlikely to be accurate, or reliable, and in fact you may not get much information at all. In fact penny stocks may not even be listed on the stock exchange at all, because of the criteria that that particular exchange may have set in order to qualify for listing.

Penny stocks are frequently offered by new companies in the stock market, which do not have much of a financial history that they can rely on. The company must perform well in the stock market if the value of the stocks is to rise, and this takes time. This means that you must be very confident of your choice before you decide to invest in penny stocks.

Even though they are a high risk stock market investment, penny stocks can be one which will produce a good profit.
