Have you looked at the newspaper and glanced at the stock market report? You will normally see graphs, values, a bunch of letters and prices. However, it would seem meaningless if you do not know what those graphs and values stand for.
The stock market would seem like a very financially technical area that many are afraid to invest in it. Not only do you not understand the graphs it also has the part where you have to spend your money in buying shares. That spending part is the scary part especially with the impression that investing in the stock market is risky.
