Summer tends to be quiet time on Wall Street... Investors leave on vacation, and so do CEOs. But what happened this year? In late July, we watched the Dow break the 14,000 point record. Then fall back below 13,000. It's rebounded a bit since, but is nowhere near 14,000 anymore. David Gardner, our Motley Fool, is back from his summer vacation. We'll talk about the wild ride on Wall Street, and what lessons investors can take from it. And check in on Neal's fantasy portfolio... Apple and Whole Foods made some news recently. What are your money questions for the Fool?
