COMMODITIES SLIDE: Commodities fell broadly Thursday, indicating that some speculators were locking in their gains and that other investors were protecting profits because of concerns that Friday's jobs reports may be worse than originally thought.
MORE JOBLESS CLAIMS: Stock indexes fell after the Labor Department said that first-time claims for unemployment benefits rose to 474,000 last week, the highest level in eight months.
THE INDEXES: The Dow Jones industrial average fell 139.41 to close at 12,584.17. The S&P 500 index fell 12.22 points to 1,335.10. The Nasdaq composite fell 13.51 points to 2,814.72.
