Currently there are 2 analysts that rate Sigma-Aldrich a buy, 1 analyst rates it a sell, and 8 rate it a hold.

TheStreet Ratings rates Sigma-Aldrich as a buy. The company's strengths can be seen in multiple areas, such as its growth in earnings per share, revenue growth, largely solid financial position with reasonable debt levels by most measures, solid stock price performance and expanding profit margins. We feel these strengths outweigh the fact that the company shows weak operating cash flow.

On the negative front, Ikonics ( IKNX), down 10.4%, NewMarket ( NEU), down 5.8%, Amyris ( AMRS), down 5.3% and American Vanguard ( AVD), down 3.9% , were all laggards within the chemicals industry with Monsanto ( MON) being today's chemicals industry laggard.
