Another rash of earnings warnings from the likes of blue-chip giant International Paper reawakened investors' jitters over dwindling corporate earnings in the weakening US economy.

International Paper, the world's largest paper and forest products company and a Dow component, joined the growing list of companies to warn its earnings would fall below Wall Street estimates as a result of the slowing economy. It dropped $1.11 to $35.11.

Casting gloom over the technology sector was JNI Corp., a maker of storage area network products, which also warned of disappointing results, blaming weakness in the tech sector. JNI slipped $1-19/32 to $7-17/32.

Coca-Cola Enterprises Inc., the largest bottler of Coca-Cola Co. soft drinks, fell $3.02 to $18.10 after saying it will miss first-quarter forecasts because of soft North American volume and increased competition. Coke, a Dow component, dropped $1.43 to $44.52.
