Needless to say, the stock market had another precipitous drop yesterday (Tuesday) as well. The last two days combined are the stock market's largest two-day drop ever, wiping away the entire gains of the last year.

A $1.7 trillion loss in 2 days. Currently the Dow is only down about 150 points down.

And with previous scares for outbreaks of Ebola or Sars, the market losses were completely regained within 6 months.
