Like with any other businesses, traders also commit mistakes in stock trading tht you can read about in business books. One of the most common mistakes is buying or selling stocks very often. This is wrong since stock rarely work steadily. Whats more, when you do this practice, it will cost you more in commissions. 

Another mistake is purchasing stocks which you think is cool. Thereâ??s no problem with going for the more popular stocks such as McDonaldâ??s because you are simply confident of its long-term growth potentials and advancing turnover margins. Then again, if you acquire it because its simply the stock to have, then you are heading in the wrong way. The reason for this is simple, you should know that they keep on going up because of their popularity, but what if they suddenly lose their fame?  Therefore, always be certain with what you want to have and why you want to have it.

Finally, buying scores of stocks is just an indication that you lack enough knowledge about stocks. On top of that, you will end up possessing a lot of stocks that you cant really track or keep an eye on. Thats only a waste of money and time as well, so avoid it.
