I expect it to explode. Frankly, the reason [these funds] get sold is that in a world of low investment returns and high valuations on equities—which is where we are—if you look at something and know what it is, you don't want it. A money market fund yields zero and has default risk. Who the heck wants that? Some people say if you own gold, you have a real thing, but nobody really buys a lot of gold. It's more playing around. You could buy a treasury bond fund that yields 2 percent. After taxes you're down to almost nothing again. I could buy stock. But stocks haven't been able to get out of their own way for 10 years and they look rich now on a P/E basis for anyone who is a true market historian.
