The idea would be to take the money with me when/if I leave the US. It depends on where I end up but there's a risk of double-taxation on any gains, plus the added hassle of multiple tax returns if I leave it here. Also, depending on the length of my future job, I might want the money for a down payment on a house.
As far as drawdown goes, I can tolerate losses, 10% wouldn't be catastrophic. This is my first foray into stocks or bonds of any kind and I'm willing to accept that it may go wrong. That said, I'd like to make the best decision possible with this.
Looking at bond funds on Vanguard, it seems the optimal option is VFSTX - short-term investment-grade fund investor shares. It seems likely to me that interest rates will rise in the next year or two, which will cause the value of the bonds to decline. Given this, is it wise to invest in a fund that is exclusively bonds? I understand the attraction given the low risk, but I thought a more diversified fund with a little more risk might be a wiser choice.
