Read the "Lies about Money" by Ric Edelman. It makes a lot of sense in putting money, diversifying and leaving it there, maybe rebalancing every now and then. According to him, most of the market biggest jumps are over short periods of time, and you never know which and when.
I have just started to save more more retirement, as med school and training salaries don't allow for much wiggle room, so a lot of these readings and research is fresh in my mind. I just need to know how to divert funds to other investment options once my 403(b) is maxed out.
Boggleheads forums is a good site.
