I realize this is a common question, and there are plenty of great answers on this forum, but its like asking "how do i drive a car?" Its going to take pages and pages of text to explain it all! You gotta do some of your own research first, then come here with a more finely tuned question, like what are the best dividend paying stocks to own in an inflationary environment?
In my opinion, there are no shortcuts to choosing a stock. As a beginner some decades ago, here's what I did: 1) Read as much as I could about investing, primarily borrowing stacks of books from the personal finance section of the library. 2) Paper traded different types of stocks: blue chips, growth, high-risk speculative, etc in different markets (up, down, sideways).
I remember when I first asked the same question, I asked my neighbor who was a trader. He said "Go watch CNBC." and...? Thats it, thats all he said to me. LOL
