here is my problem. i have around 20k that most likely will get put in some index fund. i could try to figure out (aka guess) when stocks are undervalued and jump in with all 20k then. but i'd rather set up an automatic purchase of say 1k/month for 20 months. unfortunately the fund i want has a fee of $25 fee each time i buy it. well, at least through etrade it does. that's 2.5% on a 1k monthly purchase.
any ideas?
