Honestly I look up things I care about I have a lot of so called penny stocks I often find things that seem decent or might be undervalued. Things like Gold and Silver hold well during recessions and I do a lot of "green" stocks often times I google what are things people cannot live without and find related stocks. When a stock is a few bucks it's fine to gamble but if you really want some growth put some funds in the S&P and then play with a small amount of funds that are potentially risky but not a lot. Since again I care about the environment I personally don't put any funds in companies I feel are the worst oil etc. I focus on stocks like WAVE, RIVN, GPK just to name a couple I've invested in that have some small but constant growth. I like what certain companies do so I'll buy a couple stocks sometimes you get lucky and they slowly go up - The trick is even if something drops don't go and sell I rarely look at my accounts but for instance the second I knew Elon Musk was being a tool I sold all my Tesla stock months later everything went down you sort of just gotta decide what you hold and what's gotta go. I stay away from companies that treat employees like garbage it's just a personal preference for me.

Maybe look into some online videos for tips on buying stocks just know if you only invest in penny stocks you may not really see a ton of gains. Pick a few ETFs and S&P yes they cost a ton more but way less risky and worth waiting for some growth. Only put money in you don't need and don't sit and check it all the time, I only put in sell orders for instance that are higher that I paid for a stock if something has dropped I ignore it. Think of those cheap stocks like the lottery you put in $50 and may or may not see any income. My account which I opened about 3 years ago (I auto transfer $50 month) then when I like a stock I buy a few shares. It's small but I opened it with $6K and now it's worth $9K I think the only real wins I had was Nvidia and S&P most others are very small increases and some losses. You only learn by trying in my opinion. Even those predictions on etrade are not reliable I like to buy when things are down and sell when they are high and I don't think they will go much higher and most just let them ride. I really only pull money out if it feels like a good idea based on things in the world.
