Shellback's Q3 holdings report is showing 861,799 shares of SONS. I hadn't encountered this particular institutional investor before, and I see they've only been filing 13F holdings reports with the SEC for a year or so. They're HQ'd in Boston and have about $400M in investments.
Senzar's Q3 holdings include 1,766,991 shares of ARNA. This is a new position for them. Senza holds stock in about 3 dozen companies, all of which appear to be related to or in the drug/biotech sector.
2,140,000 shares vs. 1,533,100 in Q2. Their Q1 filing shows 874,944 shares, so they have been slowly accumulating after last year's big sales.
Fact checkers, Empire's 13F-HR for Q3 came out tonight at 5:09.
The Company's net loss applicable to common shareholders for the third quarter ended September 30, 2015 was $2.8 million, or $0.08 per basic and diluted share, compared to a net loss applicable to common shareholders of $5.0 million, or $0.22 per basic and diluted share for the third quarter ended September 30, 2014. As of September 30, 2015, cash and cash equivalents totaled $22.7 million.
Ameriprise, which established a new position in ARNA during Q2 with 288,301 shares, is showing 926,858 ARNA shares in their Q3 13F report, just now posted with the SEC.
If my totals from Vanguard's 13F (just out) are correct, they had 16,676,767 ARNA shares as of 9/30. That's up from 16,296,702 shares at 6/30, a gain of about 380K shares.
As buckeye reported earlier, CRGI filed a report today that they are holding 5,281,500 shares or 10.7% of SONS shares o/s. Also from the filing:
Capital Research Global Investors holds more than five percent of the outstanding Common Stock of Sonus Networks, Inc. as of October 30, 2015 on behalf of each of the following client(s):
SMALLCAP World Fund, Inc.
Interestingly Spencer O somewhat agrees with you in his latest SA article, saying that perhaps ARNA was looking to see the street's reaction to the 10Q before the cc, and may be holding back some good news to release then.
I'm looking at the Oppenheimer 13F right now - it was filed 11/6 with a subsequent amended filing on 11/9. They're showing NO position in ARNA shares.
