STOCK market for beginners
You should never invest in something over which you lose sleep. The market is a place where anything can happen. All the money you made over a long period of time will be taken over a short period of time. All that the shareholders get in return for their money is the hope.
Making profits in shares is not in your hands, but avoiding mistakes is definitely up to you. Unless you take steps to protect yourself. You can fret and sweat over losses caused by taking excessive risk; you can also torture yourself about selling too late or listening to your advisor or friends, or indeed not listening to them. In short, you can be sorry about so many things in so many ways. These are lessons that growing retail investors will have to learn. Though it is not always easy, and sometimes fails to produce the desired results, it is always worth the trouble. It may be complicated, yet that complexity will compel you to learn new and valuable things.
Good luck and safe trading
