Are Index Funds really as good as “experts” claim?
Simply put, you cannot deterministically beat the market. If by being informed and following all relevant news, you can arrive at the conclusion that company A will likely outperform company B in the future, then having A stocks should be better than having B stocks or any (e.g., index based) mix of them. But as the whole market has access to the very same information and will arrive at the same conclusion (provided it is logically sound), "everybody" will want A stocks, which thus become expensive to the point where the expected return is average again.  Your only options of winning this race are to be the very first to have the important information (insider trade), or to arrive at different logical conclusions than the rest of the world (which boils down do making decisions that are not logically sound - good luck with that - or assuming that almost everybody else is not logically sound - go figure).
