Diversified is most likely to ease your ulcers . Putting all your money into one stock , can be very scary .On the other hand having one or a few stocks that you can really study , and understand what things affect it's likely daily changes . I kept seeing that specific tech stocks were going to zoom up , but they seemed to be keeping which particular stock that was . Eventually , I purchased several tech stocks , at the same time , for approximately the same amount of money for each stock , then let the results talk to me . I sold off the one with the lowest profit and bought more of the highest profit . It had a wave pattern to its. daily price , so I set out to buy low and sell high. Did very well all of last year, but the unexpected extremes this year , could have made me a small fortune , had I been better at realizing how extreme the prices would range .

I started with 4 stocks and slowly built to 10 with a bit of money in cryptos as well but I am planning on selling two and possible three stocks when they hit the points I am looking for. I haven't seen a heat map and will have to look into them as they sound interesting!
