Analyst Upgrades: FireEye, Sarepta, Computer Sciences

Analysts are weighing in today on cybersecurity firm FireEye Inc (NASDAQ:FEYE), drugmaker Sarepta Therapeutics Inc (NASDAQ:SRPT), and IT consultant Computer Sciences Corporation (NYSE:CSC). Here's a quick roundup of today's bullish brokerage notes on FEYE, SRPT, and CSC.

• Evercore ISI initiated coverage on FEYE with a "buy" rating and $50 price target -- in annual-high territory -- boosting the shares 1.6% ahead of the bell. Longer term, the stock has been an outperformer, rallying 31.5% year-to-date -- atop support from its 80-day moving average -- to land at $41.53. Nevertheless, half of the analysts covering FireEye Inc still consider it a "hold" or worse, which could pave the way for a round of upgrades. Today, the firm will make a presentation at the J.P. Morgan Global Technology, Media and Telecom Conference.


• SRPT was on the receiving end of a round of bullish analyst notes, after the company said it will seek regulatory approval for its muscular dystrophy drug. Specifically, no fewer than six brokerage firms bumped their price targets on the equity, while SunTrust Robinson also upgraded its opinion to "buy" from "neutral." Ahead of the open, Sarepta Therapeutics Inc is sitting on a 44% lead, as the shares attempt to battle back from their 47% year-over-year deficit, as of Tuesday's close at $16.38. Short sellers could be feeling the heat, as 39% of SRPT's float is sold short -- which would take four weeks to cover, at the stock's typical daily volumes.


• CSC announced last night it will split into two separate publicly traded companies. The decision has been met with applause on the Street, as Barclays, BMO, and J.P. Morgan Securities have each raised their price targets on the security. In addition, J.P. Morgan Securities and Morgan Stanley upgraded their ratings on Computer Sciences Corporation to the equivalent of a "hold." Ahead of the bell, the stock is perched 4.2% higher, ready to add to its 7.3% year-to-date gain to rest at $67.66. Also, CSC is poised to topple $70 for the first time since early March. On the options front, bulls have been busy in recent months, as the equity's 50-day call/put volume ratio across the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) stands at an annual high of 5.51.
