Stock Market Game 1- Initial Investment Strategy

The stock market is a relevantly new subject to me, even though I live in a city which is the home of the stock market exchange. Since I am starting with 50,000 dollars to invest in the stock market, I think I will begin by investing in one of the most known companies, like apple. I would invest in companies that I know and have purchased from. Afterwards, I think I will move on onto buying stocks from companies which are less known, but have the chance to do very well. I also plan to risk myself in these investments, but not so much as to lose all my money.
