I’m honestly curious what gives someone who doesn’t do finance all day every day confidence in their own ability to determine what is overvalued and what is undervalued? With millions of people and hundreds of funds buying/selling/holding equities, where does the confidence come from to believe one is on the smart side of any given trade? Whatever I’m buying, someone is happily selling. Whatever I’m selling, someone is happy to be buying. With the (illegal) exception of insider actionable knowledge, I feel like millions of people have already heard any good gouge I might stumble on and that info is likely already baked in. Am I selling myself short, so to speak?
