(Reuters) - Walgreens Boots Alliance Inc , the largest U.S. drugstore chain, threatened to terminate its relationship with Theranos Inc unless the blood-testing company quickly fixes the problems found by federal inspectors at its laboratory in California, the Wall Street Journal reported. The drugstore chain gave the warning in a letter to Theranos late last month, the Journal said, citing people familiar with the matter. A spokesman for Walgreens declined to comment.
The Dow and S&P 500 posted their fourth straight day of losses while the Nasdaq ended its three-day down streak. The market had traded higher for much of the session after Yellen told Congress she does not expect the central bank to reverse the rate hike program it began in December. "The market was strong (early in the day) because Janet Yellen confirmed the fact the Fed would go very slow on rate hikes because the economy was showing some signs of sluggishness," said Peter Tuz, president of Chase Investment Counsel in Charlottesville, Virginia.
NEW YORK (Reuters) - Most U.S. shares ended little changed to lower on Wednesday, erasing early gains on concerns about global growth and sliding commodity-related shares, while greater calm surrounding the European banking sector boosted that region's shares.
