Until you’ve studied the stock market for years, do not buy single stocks. The standard advice in this business gives (as far as I know) is to invest in SPY and QQQ but ONLY IF you can keep the money in for the long term (at least one or two years at the very minimum, preferably 5 years plus.)
There is a sentiment now to expect a temporary setback in the market in the near future. So you can either wait to see if that happens and buy the dip or get in now and ride the wave when it comes or put in 50% of what you want to invest now and wait on the other 50%.
I’ve heard it’s ok to invest a maximum of 2% of your investment funds on high risk stocks.
Do not get greedy. You don’t want to lose money in the stock market. It’s not pleasant!
