The amount of money you can gain or lose in the stock market is always a percentage of the amount of money you put in. How high or low this percentage is dependent on how willing you are to learn and how disciplined you are in applying what you learn.
Now, before I give you the numbers, it’s important that you understand that a high percentage and a low percentage is often compared to the market average.
For instance, in the year 2011, I gained 40%. I personally think that this is just average given that 2011 was a very good year. In fact, in one of the seminars I was attending, the professor asked one of the audience members how much money he made in his stock trading, he answered 100%. He doubled his money in just a year! Amazing!
However, if we were in the year 2008, during the time of the financial crisis, the average return was negative.
