Soros’ pick Datawatch Spikes but Continues to Struggle in 2014

Ending the day up +9.12%, Datawatch Corporation (NASDAQ:DWCH) is the day’s top gaining stock. Last week. Analysts at Imperial Capital started coverage of the company, giving it an outperform rating. A new Q1 buy for George Soros, Datawatch has had a rough go in 2014 and is down -53.51% YTD.

Agenus Inc (NASDAQ:AGEN) spiked +7.04% as the biopharmaceutical company continues to ride the wave of one of its vaccine study results. Also a first quarter Soros buy (the billionaire owns 102,000 AGEN assets), its price has climbed an impressive +43.94% in 2014.

Also having a strong Wednesday is Jazz Pharmaceuticals plc (NASDAQ:JAZZ). Its share price closed the day up +6.97%, thanks in large part to the announcement that it has signed an agreement with Sigma-Tau Pharmaceuticals to acquire the rights to defibrotide in the United States and the Americas. Jazz is yet another new Soros pick – and a recent acquisition for Steve Mandel as well.

Mazor Dips Despite Product Order Announcement

Mazor Robotics Ltd – ADR (NASDAQ:MZOR) fell -9.44% as analysts at Needham & Company lowered its price target from $21.00 to $20.00. It’s not all bad news for the Israel-based developer of surgical robots, however. Today, the company said it had received orders for and delivered four Renaissance systems during the second quarter of the year. New investor George Soros is likely intrigued to see how this plays out.

The St. Joe Company (NYSE:JOE) dipped -7.13%, though it is still up +26.89% YTD. It’s worth noting the real estate company comprises nearly 5% of Bruce Berkowitz’s investment portfolio.

United Continental Holdings Inc (NYSE:UAL) posted a -7.1% loss today, crossing below its 200-day moving average. Last week, Imperial Capital downgraded its rating of the airliner from outperform to in-line. The price of UAL has declined -15.91% over the past month, though it is still up a slight +3.81% YTD.
