Analyst Upgrades: Intuitive Surgical, Inc., Coach Inc, and Cree, Inc.

Analysts are weighing in on healthcare concern Intuitive Surgical, Inc. (NASDAQ:ISRG), fashion firm Coach Inc (NYSE:COH), and lighting specialist Cree, Inc. (NASDAQ:CREE). Here's a quick roundup of today's bullish brokerage notes on ISRG, COH, and CREE.

• ISRG closed yesterday at $473.01, and on a 10.6% year-to-date deficit. However, the shares could make a run at their 2015 breakeven level today, up 8.1% pre-market after the company reported better-than-anticipated quarterly results -- sparking a round of bullish analyst attention. Specifically, J.P. Morgan Securities and Canaccord Genuity each raised their price target to $625. On the other hand, Leerink and Raymond James cut their price targets to $593 and $570, respectively. More generally, the brokerage bunch has been optimistic toward the stock. Two-thirds of analysts have doled out "buy" or better endorsements on Intuitive Surgical, Inc., and its consensus 12-month price target of $584.29 rests in two-year-high territory.

• COH saw its rating upped to "equal weight" at Morgan Stanley, boosting the equity 1.2% in electronic trading. Shareholders are certainly desperate for gains, with the security down 20% in 2015 to rest at $30.06, and recently running into resistance at its descending 80-day moving average. Meanwhile, short sellers have set their sights on Coach Inc, with 8.1% of its float sold short -- eight days' worth of trading activity, at the stock's average volume. Looking ahead, the company will step up to the earnings plate next Tuesday morning.

• CREE reported slightly better-than-expected fiscal first-quarter earnings and revenue last night, prompting Canaccord Genuity to lift its price target to $28 from $21. As such, the stock is 2.2% higher in pre-market trading, prepared to buck its longer-term downtrend -- year-over-year, Cree, Inc. has surrendered one-quarter of its value, closing yesterday at $24.91. Traders at the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) have turned up the heat on the underperformer. CREE's 10-day put/call volume ratio across those exchanges of 1.79 rests just 5 percentage points from an annual high.
