Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Rockwell Collins (COL) upgraded to Buy from Hold at Vertical Research by analyst Robert Stoddard, as he believes there remains the possibility of the company being acquired. As detailed in colleague Jeff Sprague's related report United Technologies (UTX), the two analysts cannot rule out United Technologies making a bid for Rockwell Collins. They believe it could be more exotically structured as a Reverse Morris Trust, which would make a transaction more financially appealing to United Technologies shareholders, while preserving its credit rating, and providing Rockwell Collins shareholder with a decent premium. 2. JD.com (JD) upgraded to Buy from Hold at MKM Partners by analyst Rob Sanderson based on valuation and his belief that Chinese e-commerce is powerful enough to support "a strong number two," while the company's "position" is "sustainably differentiated." 3. IDEXX (IDXX) upgraded to Buy from Neutral at BofA/Merrill by analyst Derik De Bruin, who said new data supports 10% long-term organic revenue and 15%-20% earnings CAGRs through 2022 driven by higher diagnostic utilization by the installed base, new product ramps, and further innovation. The analyst said the pullback since the solid Q2 report provides a buying opportunity for this "top dog." 4. Intuit (INTU) upgraded to Equal-Weight from Underweight at First Analysis by analyst James Macdonald, who raised his price target to $128 from $102 following the "strong" quarter and better than expected 2018 guidance driven by Small Business growth. 5. G-III Apparel (GIII) upgraded to Overweight from Neutral at Piper Jaffray by analyst Erinn Murphy to reflect the recent pullback in shares and maintained a $27 price target. The analyst expects wholesale trends to "fuel upside" and believes the new DKNY product is checking well at retail. To see The Fly's full Street Research coverage, click here.
