For us, with hundreds of online stock trading sites at our disposal, it is difficult to even imagine a world where buying stocks online did not exist. Yet a short twenty years ago this was not possible. In 1990 you still had to personally contact a broker before you could buy stocks.

The Internet made a fundamental change in the way the buying and selling of stocks work. Firstly you can now invest in stocks without ever having to meet a broker in person or ask him for advice. There’s still a broker involved in every transaction, but you do not have to know who he is or to deal with him personally.

Not only did the way the actual buying or selling is carried out change, there were many other changes as well. Probably the single biggest change in the market was the incredible amount of information that became available to investors and traders since the Internet appeared on the scene.

It does not matter which stock you are investigating, you now have access to a huge amount of information about that company merely by visiting a couple of websites. You can track its stock price for the last twenty years and get expert projections of where the price is heading for. You can study the financial statements and read what market experts think of the stock.

To prevent information overload, the individual trader or investor needs a system to analyze this huge amount of information. He needs to devise a set of rules or criteria to evaluate different stocks before making a decision to buy or sell one of them.

Never let the real reason for all your research slip your mind. You are looking for a stock that is undervalued. A stock which has huge growth potential and the market has not yet caught up to this.

There’s a large number of formulas and criteria you can use to evaluate stocks. Many books have been written about the subject. A simple rule of thumb is that the P/E (Price/Earnings) ratio of the stock must be lower than what you calculate the future profitability of the company to be. A company with a low P/E ratio which does not seem to have discounted these high future profits is always a good buy.

To find a clearly undervalued share in today’s market is not easy and will take time. You will need to analyze a lot of company information and even ask questions at online investment forums before you can be sure you have found a good opportunity. Buying stocks online is easier than ever before, but that does not mean it should be done without first doing the necessary homework.
