Of course!! Now why is it that all these institutional investors spend all that money on so much research...
... because someone else is willing to pay them for it.
There are good reasons to invest in a S&P 500 index fund.
1. Fees are very low because no research is needed or being paid for.
2. Successful investments are measured against the S&P 500, which usually include a lot of research being paid for. Just skip the middle man.
3. Is large scale research worth it? Remember the anecdote that ends with, “Where are the customers’ yachts?”
