So invest in s&p 500 and do nothing, right? That's a good strategy for someone young, because it makes sense to be risk tolerant then. As you age you want more and more of your portfolio in bonds/cash, because you want the reduced fluctuation in purchasing power (i.e. comfort) that that brings you. These are the bare fundamentals of portfolio management.
If you are young, you might even want to invest more than 100% of your portfolio into the S&P 500.
