"Just put it in the stock market. You'll always make something." I heard that from someone over the weekend. Scout's honor. And it's true, depending on your definition of "make." If you're sitting on a spare, say, $100,000 that's currently dying of boredom in a money market fund, you can move it into a handful of blue chips and generate a little bit of income. The figure (below) just shows there's still some $4.3 trillion idling on the proverbial "sidelines" -- the ubiquitous "dry powder."
