Now I feel that investing can be risky for me. Because during the week of investments. I used to risk a lot to win more. I've learn the lesson that you should the news of the companies you have invested. Also if you've invested in a company that is not winning that much you should be patient. Another thing that I learned was that you have to do smart moves. If one of the companies is not winning and it's making you loose you should sell it and look for another company.
The advice that my gave was that I should invest in the companies I knew more. For example, Disney and 21st Century Fox. As wall invest in companies that have regular or low increases. Another advice is that I should check my portfolio every five minutes cause it will be changing.
