Midday Report: Job Openings Hit All-Time High; U.S. Stocks Waver

Stocks fluctuated on Wednesday morning as investors stood on the sidelines until any further rate-hike clues surface. The Federal Reserve's Beige Book will be out this afternoon. Job openings rose to an all-time high in July, the latest sign of a tightening labor market. Higher voluntary resignations also signaled workers were more comfortable quitting current jobs to pursue other opportunities.  HD Supply (HDS) - Get Report stumbled after issuing disappointing forecasts for its current quarter. The industrial products company also said preliminary results for August showed flat sales in its facilities-maintenance segment, its largest unit. Delta Air Lines (DAL) - Get Report guided for a $150 million decline in current-quarter pretax profit. The bulk of the decline was tied to a technology glitch that caused flight delays over several days in August.
