Jump processes and the implied volatility curve

It is a commonly held belief that markets tend to both over-react and under-react to the arrival of good or bad news. Market confidence can drive up values of stocks, and market fear can lead to large negative dips in stock value. In early September 2008, Bloomberg mistakenly republished a 2002 article where it set out that United Airlines had sought bankruptcy protection from its creditors[1].
