When I am looking at investing my money in a company, I always like to do a lot of research and make sure my decision is based on sound research.
I seldom make quick decisions when I am buying or selling stock. I have a lot of respect for proprietary traders who can handle the stress and consistently do well.
I remember reading once that being a stock trader is one of the most stressful jobs there is. This is not something I would willingly take on.
Even though a successful proprietary traders salary is much more money than I make, I don't think it would be worth it to me.
