NEW YORK ( TheStreet) -- Several stocks trading under $10 were poised to move on above-average volume during Monday's session. Santarus ( SNTS) jumped by 29 cents, or 5.8%, to $5.27 in the premarket session after Santarus announced that the U.S. Food and Drug Administration (FDA) had approved the its New Drug Application (NDA) for immediate-release of a prescription tablet product for the treatment of heartburn and other symptoms associated with gastroesophageal reflux disease. Santarus has now submitted an NDA supplement requesting approval of a proposed trade name that includes the "ZEGERID(R)" brand name and anticipates that the FDA will complete its review of this NDA supplement within 180 days. The 50-day average daily volume for Santarus is 538,000, according to the Nasdaq. JA Solar ( JASO) was among the most active pre-market trades, jumping by 17 cents, or 3.5%, to $4.40 in the premarket session on Monday. The solar company saw a spike in trading after a Barclays' research recommendation upped JA Solar and some of its peer companies to an overweight. The 50-day average daily volume for JA Solar is 4.7 million, according to the Nasdaq. Allos Therapeutics ( ALTH) dropped 72 cents, or close to 11%, to $5.90 in the premarket session after a report in The New York Times criticized the pricing of the firm's marquee drug. The biotech firm also announced the latest results from its FOLOTYN trials, a lymphoma drug, but while the company spun the results as "continuing to show the effectiveness of the drug," shares were down the most of any actively traded stock under $10 on Nasdaq on Monday morning in the aftermath of the Times article from last Friday. The 50-day average daily volume for Allos is 2.9 million, according to the Nasdaq.
Brocade Communications Systems ( BRCD) rose by 24 cents, or 2.8%, to $7.24 in the premarket session, after an upgrade from Oppenheimer analyst Ittai Kidron to outperform, and a new price target of $8.50. The analyst argued that Brocade will benefit from the distraction from Hewlett Packard's ( HPQ) purchase of 3Com ( COMS) and Avaya Inc.'s acquisition of Nortel ( NRTLQ) enterprise business. The 50-day average daily volume for Brocade is 26.9 million, according to the Nasdaq. -- Written by Eric Rosenbaum in New York.
