US stocks Monday opened mixed as drugmaker Gilead Sciences and agricultural products giant Monsanto both fell.
Five minutes into trade, the Dow Jones Industrial Average was at 18,152.61, up 24.96 points (0.14 percent).
The broad-based S&P 500 added 1.11 (0.05 percent) at 2,109.21, while the tech-rich Nasdaq Composite Index fell 7.97 (0.16 percent) to 5,018.45.
Gilead Sciences dropped 1.6 percent on news that it issued a warning about its hepatitis drugs after nine patients had suffered abnormally slow heartbeats, and one patient had died.

US stocks stand near record highs after a rally last week following a Federal Reserve policy statement that pledged a cautious approach to raising interest rates.
