How do you analyze a stock to see if it’s a good buy right now? Especially with so many factors that go into it. Are these good buys?

I wanna start getting back into investing but haven’t gotten around to it. I’m fairly young, in my early 20s, and have about $3500 sitting in a savings account that is doing absolutely nothing for me right now. How do I analyze a stock to see if it’s a good buy or if i should wait? It’s especially confusing to me right now with inflation and the Ukraine war which i think has majorly affected our stock market.

Here is a list of stocks that i’m looking to potentially invest in:

FB/Meta: Seem to be at a massive discount right now, i know earnings is coming up soon for them. They seem like a great mid to long term buy

AAPL: It’s apple, can you ever go wrong??? But they definitely don’t seem like a discount right now, still a buy?

Wayfair: Seem to be at a huge discount right now, but i haven’t kept up with them as a company recently.

Alibaba: Same as Wayfair

Shopify: Same as above 2

Every ETF out there like VOO, VTI, SPY, VXUS
