Since I am new to this investing stuff...the advice I was given by a friend who day trades was this:
Go to a free stock screener online like this one:
https://www.barchart.com/etfs-funds/quotes/SPY/overview
Pick a market sector you are interested in, or simply one that is doing well. In the above screener, go to "stocks" then go down the left side to "sectors" and pick one. This will show you a bar chart showing how each sector compares to the others at that moment.
As I write this, "energy" is the top performing sector. If you click on "S&P Energy" it will give you a list and ranking of each individual stock within that sector.
Start watching the top 10 or so and see how each one progresses.
You can also do this with any "ETF" (Exchange Traded Fund) as well. There are numerous places online to find out what the top 10 "Holdings" are for each fund. You gotta figure that if the fund managers included them as the heaviest weighted holdings, then they have been vetted.
