Volume Spike Investor

Sequenom Inc. (Nasdaq: SQNM) shares are up nearly 10% on a strong volume as of 10 a.m. Eastern, as speculators appear to be analyzing its worth as a takeover candidate, now that genetic testing rival Monogram Biosciences Inc. (Nasdaq: MGRM) was acquired by LabCorp. for $4.55 a share, a 170% premium.

Both companies are forwarding DNA-based testing that is helping to make a push for personalized drugs based on gene sequencing technology.

The rumor mill has been very active in this stock ever since its end of April implosion, when shares dropped from nearly $15 to less than $4. The stock was hit after the company discovered employee mishandling of R&D test data and results that eroded investor confidence in the company’s DNA-based tests. – Mike Tarsala
