SodaStream, Container Store lose a fifth of their value

SodaStream estimated third-quarter revenue below market expectations, citing weak demand in the United States, and its shares fell as much as 21.6 percent. They were last trading down 20.9 percent at $21.80, with volume more than 2.7 times the average of the past 10 days.

Container Store posted lower-than-expected sales for the second quarter while cutting its full year sales forecast. The stock fell as much as 24 percent and was recently down 23.8 percent at $16.67 in about 8 times its recent daily volume.

On the flip side, Hubbell's class A and B shares both hit record highs on Tuesday after Reuters reported the trustee of the company's controlling family trusts is evaluating alternatives for their holdings. The news could lead to a shakeup at the $7.2 billion U.S. electrical equipment maker.

Its class A shares were gaining 5.6 percent at $131, and the class B stock were adding 2.4 percent to $124.23 after earlier hitting $127.29.
