A survey of the damage: The S&P 500 and Nasdaq - both solidly red for the year - managed to reach correction status (10% drop) in just 9 days. The Russel 2000 is down 7% for year. The worst performing sector today, energy, -6.8% as crude oil plummeted a similar amount. Dow Theory to the rescue? Not so much as the transports fell 5.1% today, down 7.7% YTD.
