The Russell 2000, dragged down by most of the above stocks, tumbled 1% to 787.8 to chase the S&P SmallCap 600, which lost 1.2% at 410.1.
Hoku Scientific (HOKU) ranked among the few winners, however, leaping 11% after the Hawaii-based clean-energy company inked deals for the construction of a new polysilicon production plant capable of churning out 2,000 metric tons of polysilicon a year. Contracts were awarded to JH Kelly and to a Shaw Group (SGR) subsidiary. The project's total installed cost target is $260 million, and it's slated for mid-2009 completion. Shares were up $1.04 to $10.50.
The Knot (KNOT), a wedding-planning Web site, posted flat second-quarter income vs. last year -- 15 cents a share -- but that squashed analysts' dime-a-share targets. Revenue soared 60.7% to $28.5 million, which likewise topped the consensus. Shares of the New York-based company bounced $3.07, or 16.4%, to $21.75.
