Dow Swings On Economic Uncertainty And Ebola Fears

On a combination of economic uncertainty, Ebola panic and general October volatility, the Dow has tanked more than 400 points in midday trading, falling below the 16,000 mark and hitting its lowest level in nearly three years. The S&P and Nasdaq aren't faring much better -- both are down more than 2% -- while the volatility index has surged to its highest levels since the Eurozone crisis.
