Allegiant gains, Southwest falls on turbulent day for US stocks. GDP slowdown imminent

Another rally on US stock markets yesterday was brought to a halt when the Federal Reserve issued a revised forecast for US GDP growth in 2010, trimming expectations from 3.2-3.7% to 3.0-3.5%. The Conference Board stated the rebound effects from the recession have "almost entirely dissipated" and a growth slowdown starting this summer is "becoming increasingly apparent".
