Jazz net declines 38% in Q2; Continental Airlines and United Airlines to divulge new information

North and South American airline stocks were down on Tuesday (04-Aug-2010) as the Dow (-0.4%) declined on disappointing earnings results and economic data. Investors are concerned that the market's strong performance in Jul-2010 was based on an exaggeration of the economic recovery, following recent weak data on housing, factory orders and consumer spending.
