I moved most of mine to an ex-US fund that's offered by my 401k plan, but even that is going to take a large hit when the bubble pops. My concern is that the U.S. market has been propped up by enormous government expenditures into R&D that are no longer happening, so I was leery of just standing pat. But I plan to simply ride out the crash while continuing to toss money in from every check, which I believe is the safest, most sensible way to go about it, for a long-term investor.
