Analyst Update: Boston Scientific Corporation, InvenSense Inc, and VMware, Inc.

Analysts are weighing in on medical device name Boston Scienfitic Corporation (NYSE:BSX), sensor maker InvenSense Inc (NYSE:INVN), and tech stock VMware, Inc. (NYSE:VMW). Here's a quick roundup of today's brokerage notes on BSX, INVN, and VMW.

• BSX is up 1.8% at $24.25 – within a chip shot of a new 10-year high -- after an upgrade to "buy" from "hold" at Argus Research. The stock has had a standout year, up over 30% since the beginning of 2016, with a few minor dips contained by BSX's 50-day moving average, which has supported the stock since March. Sentiment towards the stock is positive, with 14 of 18 analysts rating the shares a "buy" or better, and without a single "sell" in sight. Meanwhile, in the option pits, Boston Scientific Corporation has seen 11.60 calls bought to open for every put over the last two weeks at the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX).

• Roth Capital began its coverage of INVN with a "buy" rating and $9 target price, and the wearable tech stock is now up 2.2% at $7.60. INVN has lost over a quarter of its value so far in 2016, with the shares repeatedly encountering resistance at the $8.50 level since mid-January. InvenSense Inc's option pits have seen some bullish action as of late, with INVN's 10-day ISE/CBOE/PHLX call/put volume ratio of 7.07 ranking higher than 80% of all other readings from the past year.

• VMW is trading up 1.3% at $74.28, after it was announced earlier this week that Dell Inc landed China's approval to acquire VMW's parent company, EMC Corporation (NYSE:EMC). Last night, Mizuho raised its target price on VMW to $66 from $61, while UBS this morning bumped its price target to $83 from $77. VMWare, Inc. is up by 31.3% since the beginning of 2016, though it is still struggling to touch its 2015 highs in the $93 neighborhood. With short interest up over 18% in the last two reporting periods, shorted shares now account for over 31% of VMW's float, which would take over two and a half weeks of trading to cover, at the stock's average daily volume.
