When you invest in stocks ISA , how do u know which companies do u invest in , should u look at individual companies and their history and their future plans and put money in it , or do u just follow the hype / others portfolio and copy them , I see 90% of people saying S&P put surely investing in Indian company is ideal to like Nasdaq etc

Am 24 years old and just put in my first £700 into intel / sofi and nvidia but not sure how to pick out where I need to put my money in
