Hey,
I agree with the previous. I've owned this since before 9/11 and bought high at first, and continued to add to my Roth IRA trough the trough. Sure, a loss of 9% YTD is poor. I'm still concerned over its performance too, but even a modest rise in the market will change everything for us all. My recommendation is to hold and add when you can. You're $$ is about as good here as anywhere you'll put it, and many are doing worse. With the market in a slump, you don't want to do anything crazy.
Good luck to all, and God Bless,
