I understand diversification mostly. You don’t want all your eggs in one basket. That way if a segment of the market fails, your whole retirement isn’t shot.
I have 35 years until retirement. My main goal is becoming debt free, so that’s where most of my money goes. Still, I invest enough in my 401k to get my employers 100% match. And I am putting 50 a month into a Roth Ira (just to get in the habit of investing and learn about it).
My 401k is a low expense SP500 index fund. My Roth is basically the same style but different name fund.
Does the fact that these are index funds provide enough diversification? At this point we are only talking less than 10k. Should I diversify more when it is larger or is this OK for long term?
Congratulations on getting started early - it will pay off big time if you continue.
One index fund is a great start, but it is not diversified. It is not complicated to set up a diversified portfolios, in fact I would avoid complicated with an approach like this.
The Bogleheads forum has some pretty solid investment advice for typical investors saving for retirement. Probably the easiest strategy is the three fund portfolio. Basically, just choose a mix of low-cost index funds that give you domestic stock, international stock and domestic bond exposure, e.g. Vanguard Total Stock Market Index (VTSMX), Vanguard Total International Stock Index (VGTSX), and Vanguard Total Bond Market Index (VMBFX). Then set up automatic contributions and regular rebalancing and forget about it.
I agree.
If you like fiddling about with things, you can then add more funds to, say, weight toward smaller-cap stocks, add an REIT fund, foreign market diversification (e.g. emerging markets), etc. Fun times.
But three funds is a good place to start.
Also re: debt reduction, that’s a very good thing. However, if the interest rate is really, really low, it can be better to invest it (e.g. to get your employer match, as you are doing.)
