Why Chicago Bridge & Iron, Akorn, and Flotek Industries Slumped Today

Monday wasn't a good day for the stock market, as most major benchmarks gave up early gains to finish lower. Investors continued to be nervous about interest rates, which appear to be on the rise as a strong earnings season continues. Consistently climbing oil prices also have had a mixed impact on market sentiment, with energy investors generally liking the trend while others worry about the potential inflationary impact that higher costs could bring.

Adding to the gloom was bad news about some individual companies that sent their shares sharply lower. Chicago Bridge & Iron (NYSE: CBI), Akorn (NASDAQ: AKRX), and Flotek (NYSE: FTK)were among the worst performers on the day. Here's why they did so poorly.
