Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Ormat Technologies (ORA) upgraded to Overweight from Neutral at JPMorgan by analyst Paul Coster. The company reported mixed Q2 results and guidance owing to disruption at the Puna plant in Hawaii, but Coster believes that when excluding Puna, Ormat's execution "remains solid" and the company's long-term growth prospects "remain undimmed." 2. Wright Medical (WMGI) upgraded to Buy from Neutral at BofA/Merrill by analyst Travis Steed, who cited increased confidence in 2H 2018 and 2019 double digit growth and upside to Street estimates. Steed said growth in the core lower extremities business returned to market rates for the first time since Q1 2016 and believes it can accelerate further from new products and productivity ramps. 3. WildHorse Resource (WRD) upgraded to Buy from Hold at SunTrust by analyst Welles Fitzpatrick, who noted that the 13% decline in the stock price "makes little sense" from differentials or CapEx point of view, adding that the move in pricing does not warrant the large decline. Fitzpatrick views WildHorse Resource as a "simple, single-basin story, with distinct, quantifiable advantages such as premium oil pricing given its gulf coast access, ability to realized material savings with an in-field sand mine, and optionality to expand its midstream system." 4. ITG (ITG) upgraded to Overweight from Neutral at JPMorgan by analyst Kenneth Worthington, saying that the company's fundamentals are improving as it gains "traction on a number of fronts" that have and will continue to drive higher earnings power over time, particularly outside the U.S. 5. Comstock Resources (CRK) upgraded to Buy from Neutral at Ladenburg by analyst Michael Schmitz, who said the recent pullback in shares provides an attractive entry point.

Mizuho raised the firm's price target on Comstock Resources to $10 from $9 and keeps an Underperform rating on the shares. The company already dropped two rigs and cut the dividend in response to lower gas prices, the analyst tells investors in a research note. The firm says that although investors will likely look for further reductions in activity, the remaining rigs are active on projects so another drop is unlikely until late Q2.
