How do you know when a rebound can really come about in highly volatile stocks-or in general stocks really?

Hey folks! I am a new trader who has been studying how the stock market works and became interested in it because of meme stocks. That was how I started, and recently, after losing a little money I can afford to lose due to how volatile and stagnant they can be at times, I am trying to figure out how to avoid the worst-case scenario again. For now, I am just doing paper trades to avoid worrying about real losses anymore and on the search for normal stocks.

This brings me to my question: With stocks like these, how can you figure out which ones are likely to continue dipping sharply after a big hit? On the other side, what about when a stock dips 8% or more but you cannot tell in the moment whether it could get worse? It's so hard in the moment because I can never tell even knowing the companies directory. I keep on thinking that somehow it would recover only to get screwed later. I know that volume can help as well as average price range, though I don't really know how exactly a low or high volume(including P/E) could indicate a rebound in that moment.

I am pretty curious because all of this fascinates me, and any advice would be super helpful! I have no idea what factors matter when evaluating a normal stock, and I have been reading more to prevent repeating past mistakes. I have been using stop losses alot more for sure for sure.

Thanks!
