Analyst Update: JinkoSolar, Etsy, Sorrento Therapeutics

Analysts are weighing in today on alternative energy issue JinkoSolar Holding Co., Ltd. (NYSE:JKS), e-tailer Etsy Inc (NASDAQ:ETSY), and drugmaker Sorrento Therapeutics Inc (NASDAQ:SRNE). Here's a quick roundup of today's brokerage notes on JKS, ETSY, and SRNE.

• JKS is following its sector south, off 0.8% at $28.23. Also weighing on the solar stock is a price-target cut to $42 from $45 at Credit Suisse. However, from a long-term perspective, JinkoSolar Holding Co., Ltd. has been red-hot, gaining over 43% in 2015. Not surprisingly, option traders have tilted in a bullish direction at the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX). JKS' 10-day call/put volume ratio across those exchanges is a top-heavy 7.47, and outranks 94% of comparable readings from the prior 12 months.

• ETSY has given back 0.9% at $8.64, after Roth Capital initiated coverage with a "sell" rating and $5.75 price target -- representing record-low territory for the shares. The skepticism is understandable, given the stock's underperformance. Specifically, Etsy Inc has lagged the broader S&P 500 Index (SPX) by 41.6 percentage points over the past 60 sessions. Short sellers see more downside in store, too. A healthy 9.3% of ETSY's float is sold short, which would take almost nine sessions to repurchase, at average volumes.

• After being started at FBR with an "outperform" endorsement and a $22 price target, SRNE has jumped 17.4% to trade at $9.22. "We believe Sorrento has a lot of optionality and uncertainty but huge potential," the brokerage firm wrote. Today's bullish gap has trimmed SRNE's year-to-date deficit to 8.3%, and brought the shares near their 80-day moving average, which hasn't been toppled on a closing basis since Aug. 17. Optimism is commonplace among the analyst community. All three brokerages tracking Sorrento Therapeutics Inc have designated it a "strong buy," while its consensus 12-month price target of $27.20 nearly triples current trading levels.
