Helicos Shares Soar in Mixed Month for GWDN Stocks

NEW YORK (GenomeWeb News) – Shares of Helicos BioSciences rose nearly 400 percent during the month of August, far outgaining the other 35 stocks that comprise the GenomeWeb Daily News Index.

Shares of Helicos, the Cambridge, Mass.-based single-molecule sequencing technology firm have risen sharply since Aug. 10, the day a paper appeared in the journal Nature Biotechnology, which detailed how the company's Heliscope sequencer was used to sequence the genome of Stephen Quake, one of the firm's co-founders.

Since then, Helicos has announced that it has placed Helicos Genetic Analysis Systems, which include the Heliscope sequencer, at Massachusetts General Hospital Cancer Center and the Ontario Institute for Cancer Research.

The rise in Helicos' share price was far greater than any of the other gainers in the Index for the month. Other stocks that rose more than 15 percent for August included Response Genetics (+39 percent) — which is new to the Index this month, Genomic Health (+19 percent), Accelr8 (+18 percent), and Compugen (+17 percent).

Of the 12 stocks in the Index that lost ground during the month of August, the biggest decliner was Exact Sciences, which fell 23 percent. Affymetrix also fell 13 percent — offsetting its 49 percent rise for the month of July, and Pressure BioSciences dropped 12 percent.

Overall, the GWDN Index increased 4 percent for August, roughly the same amount as the Dow Jones Industrial Average. The Nasdaq finished August up just under 2 percent, and the Nasdaq Biotech Index fell less than 1 percent.

Ed. note: Response Genetics has replaced Monogram Biosciences, which was recently acquired for $107 million by LabCorp, in the GWDN Index.
