Irvine-based drug maker Allergan Inc. was down 1% to $164.11 and a market cap of $48.8 billion.

Newport Beach-based chemicals maker American Vanguard Corp. was up 3% to $13.07 and a market cap of $376 million. Second quarter 2014 sales and income met analyst estimates despite declines and the company offered positive guidance going forward. Net sales fell to $68.3 million from $86.8 million year-over-year while income was flat at $0.1 million from $8.4 million in the same period last year. The company said surplus inventory and increased fixed factory costs reduced profits in the quarter but expects normal purchasing patterns and lower operating expenses in future quarters.
