The volatility of the first quarter that ended Friday, was reflected in several stocks that saw unusual activity during the week, including a drop for Boston Scientific and a jump for Abbott Laboratories.
Boston Scientific Corp. slid 6.6 percent Monday after a study showed a heart stent made by Abbott had lower rates of target vessel failure. This means the drug-coated stent performed better than Boston Scientific's Taxus.
The study was originally meant to show that the Abbott stent, called Xience, was merely not inferior to Taxus. Both stocks traded with very heavy volume, and sent shares of other stent makers into accelerated trading as well.
Shares of Boston Scientific sank to a nearly five-year low of $13.88 on the news, with volume approaching three times its typical trade of about 12 million shares. The New York Stock Exchange-listed shares recovered slightly as the week continued as volume returned to more normal levels, ending the week at $14.54.
Meanwhile, Abbott shares on Monday gained 6 percent and hit an all-time high of $57.26, with trading volume almost four times a typical day. Volume remained high Tuesday as shares began to slip a bit, and by Friday the stock settled back to close at $55.80, still up 3.6 percent for the week.
Nuvelo Inc. shot up 25 percent Tuesday to $3.86, after the smallcap company said the Food and Drug Administration has granted "fast-track" status to its colon cancer drug candidate as both a first- and second-line treatment.
That means Nuvelo can submit data to the FDA on a rolling basis rather than all at once, speeding up the application process.
Trading volume jumped to about 9 times its usual volume, with 28 million shares changing hands on the Nasdaq Stock Market. Activity remained high Wednesday, though volatility leveled out. The stock gave back some of its Tuesday gains but ended the week up 19 percent at $3.68.
On Wednesday, Beazer Homes USA Inc. plunged more than 8 percent to $28.77 on the NYSE, after the FBI said it is among agencies investigating possible fraud in the company's mortgage lending practices and other financial transactions.
The homebuilder said it was cooperating with a federal prosecutor's request for documents. The news came on top of ongoing struggles for the Atlanta-based company, which has suffered hefty losses amid a downturn in the housing market.
Trading volume swelled to 19.6 million shares changing hands, from a typical level of 1.6 million shares.
The U.S. attorney's office in Charlotte, N.C., along with the Internal Revenue Service and the U.S. Department of Housing and Urban Development are also participating in the investigation.
Volume settled back down the rest of the week, though the stock didn't recoup much of the loss. Shares of Beazer ended the week down 7.6 percent at $29.03.
RF Micro Devices Inc., which makes components used in mobile phones, on Thursday shed 11 percent to end at $6.31 on the Nasdaq, after the company projected a first-quarter slowdown. Trading volume zoomed to 63.3 million shares, from a usual 8.7 million shares changing hands.
The news prompted a Jefferies analyst to downgrade the stock. The company blamed lighter demand from a top customer, but did not provide more details. Analysts suspect the customer is mobile phone maker Motorola Inc., which recently warned of a more than $1 billion expected sales miss.
Shares lost another 8 cents Friday, with volume nearing 40.6 million shares, to close the week at $6.23.
Friday, Dendreon Corp. more than doubled its share price with extraordinarily heavy trading volume, surging $7.71 to $12.93 on the Nasdaq, and during the session spiked to $18.05, its highest point since December 2000. Volume approached 92.5 million shares, more than the 75.7 million shares the company had outstanding
The drug maker said a Food and Drug Administration panel endorsed its experimental prostate cancer vaccine, Provenge. The FDA advisers said the vaccine is safe, and said there is substantial evidence that it works in treating advanced prostate cancer that no longer responds to hormone treatment. The drug needs further study before it can be approved.
