I'm glad you said this.
My DH gets cranky when I want to just keep cash, and here we are, he thinking "we've got too much in cash" yet in his estimate, it's only about 15 - 20%. I personally haven't run the numbers. But I did pull out 2/3 of my own 501k-type investment and put it into cash in fall 2013. And yes, I missed some of the stock market run up, but I am ok with that. The high stock market numbers right now make me nervous.
After hearing this I think I'll look to see where else we can cash in some investments.
