I have ~ 20-25k I would like to invest long term in addition to what I'm putting in my IRA and 401k this year. By long term I mean I shouldn't need the money (hopefully) for 20 years or so. So, I plan on opening a brokerage account somewhere (right now I'm considering ScottTrade and Vanguard) and setting up an automatic investment schedule. My thinking was it would be better to invest the money slowly throughout the year (or even longer) to avoid any accidental bad market timing.
Does this sound reasonable? Vanguard has no fees on all it's ETF's so I thought of going with them to avoid transaction fees, but I guess I need to look at their ETF's and also figure out if ETF's are a good investment for a taxable account.
I'm curious what sort of investments would be best for a taxable account? Which online discount broker would you recommend? Any other strategies for moving this cash into investments?
