Analyst Update: Skyworks Solutions, Infoblox, Trina Solar

Analysts are weighing in today on semiconductor producer Skyworks Solutions Inc (NASDAQ:SWKS), tech interest Infoblox Inc (NYSE:BLOX), and solar power concern Trina Solar Limited (ADR) (NYSE:TSL). Here's a quick roundup of today's brokerage notes on SWKS, BLOX, and TSL.

• SWKS is trading 1.9% higher at $79.21 -- in spite of a price-target cut to $120 from $132 at Canaccord Genuity -- thanks to the news that PMC-Sierra Inc (NASDAQ: PMCS) will be bought by Microsemi Corporation (NASDAQ: MSCC), finally ending the bidding war between MSCC and Skyworks Solutions Inc. This development will likely send the shares even higher as SWKS bears head for the exits. The stock's 50-day put/call volume ratio at the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) sits higher than 93% of comparable readings from the last year -- indicating a significant preference for puts over calls in recent weeks.

• BLOX got slammed with a fresh round of analyst downgrades today, with Needham cutting its rating to "hold" from "buy," while Deutsche Bank not only dropped the stock to "sell" from "hold," but slashed its price target on Infoblox Inc to $13 from $20. This negative attention has the shares down 11.5% at $13.93, just off a new one-year low of $13.22. BLOX has shed more than 31% of its value in 2015, so bears are already familiar with the stock -- the number of BLOX shares currently sold short account for more than five times the equity's average daily volume -- but today's dip has landed the stock on the short-sale restricted (SSR) list.

• TSL is up 3.2% at $9.40, after taking a fall on a disappointing earnings report yesterday. RBC, Cowen and Company, and Roth Capital all cut their price targets on the stock, but the 12-month consensus price target on Trina Solar Limited is still at $14.26 -- a level not seen in over a year, and a 52% premium to the stock's current price. On a year-to-date basis, TSL is up a slight 1.5%, but options traders are betting on more losses. With a Schaeffer's put/call open interest ratio (SOIR) of 1.69, in the 100th annual percentile, options traders have never been more put-heavy in the past year. This pessimism is unsurprising, considering that solar stocks are historically the worst performers during the fourth quarter.
