Nanosphere (NSPH) soars 19.1% into the stratosphere and hits $3.02 as Jefferies upgrades the company to buy from hold. Jefferies expects the firm's bloodstream infection test, which the FDA approved last week, to "drive a significant acceleration in new system placements and revenue." Jefferies also ups NSPH's price target to $5/share from $2.
