I opened this thread hoping to see some good advice. No offense to anyone who tried to help, but I don't see any suggestions that look particularly insightful (other than perhaps the Roth, but I think it's safe to assume that's not the advice you were looking for.) Actually, Tallgeese had a good comment - no, not about the two chicks - you can draw considerably more interest without increasing your risk my looking at a money market account.
I don't think you're going to find a lucrative investment right now in the traditional channels. Of course, we never know when the stock market might start a huge upswing, but I think most people who are knowledgable about this subject aren't expecting one for some time. Safer investments are getting such a low return (as you pointed out) that it's almost not worth it. It's just not a good time right now. Maybe most of us should be thankful we're not retiring in the next 5 years.
The best suggestion I can think of is to tie it up in a CD for a year or two to draw better interest, and then re-evaluate. Unless you know some smaller personal investment that could bring a good return, I don't think you're going to get much in today's market (and with this damn war threat, you actually risk things getting even worse.)
Option 2 (my favorite): Add about $5k to $10k more and buy a nice beach house in Brazil. With the dollar so strong and the Brazilian Real so weak, you can get a great little place on the beach for around $15,000. Even if your investment doesn't appreciate that much, imagine the value you get out of it in the meantime!
