Successful investing is playing the game of maximizing potential profit while minimizing risk. For most people (who don’t have ten hours a day to study the health of businesses and economies) this means buying something low risk, meaning unlikely to experience a catastrophic loss, like VOO or the S&P. Optimally an active investor is constantly looking for the best place to park their money, which changes day to day, month to month, etc.
But only do active stuff if you have some reason to be really confident. Always remember that there is a person on the other side of the trade from you, and statistically that person is someone who spends 60h+ a week looking at stocks, and is happy to sell at the price where you’re buying / vice versa. You should be confident that you know better than them
