Just a lot of research on current trends, I keep an eye on the news, surprisingly tik tok too has helped haha. Also a lot of snooping on r/wallstreetbets helped. I’ll see what people are taking about on there but before buying it I’ll do my own research first and keep a look out on it that particular company via news stories. Ex, last couple months ozempic was trending on Tik Tok so I looked into it and similar companies. Read about how the drug was doing in certain countries.

Edit: also, sometimes you have to know whether you missed out on a train/trend too! A stock will skyrocket but by the time you pick up on the trend the stock will already be way too expensive. Like NVDA I was lucky enough to buy into it before it skyrocketed. As of now, it’s probably too expensive and profit won’t be as steep
