Research Analysts’ updated eps estimates for Monday, August 7th:

Aegion Corp (NASDAQ:AEGN) had its hold rating reaffirmed by analysts at Stifel Nicolaus. They currently have a $23.50 price target on the stock.

Armstrong Flooring (NYSE:AFI) had its hold rating reaffirmed by analysts at Stifel Nicolaus. The firm currently has a $20.00 target price on the stock.

Ladenburg Thalmann Financial Services initiated coverage on shares of AIT Therapeutics (NASDAQ:AITB). Ladenburg Thalmann Financial Services issued a buy rating on the stock.

Align Technology (NASDAQ:ALGN) had its buy rating reaffirmed by analysts at Stifel Nicolaus. They currently have a $205.00 target price on the stock.

Arista Networks (NYSE:ANET) had its buy rating reiterated by analysts at Argus.

ANSYS (NASDAQ:ANSS) was upgraded by analysts at Zacks Investment Research from a sell rating to a hold rating. According to Zacks, “ANSYS reported better-than-expected second-quarter 2017 results which also marked year-over-year improvement. An upbeat 2017 outlook was also encouraging. ANSYS is a dominant player in the high-end design simulation software market. Notably, ANSYS has outperformed the industry in the last one year. We believe that robust product portfolio, expanding total addressable market (due to rising complexity in manufacturing IoT related products), improving enterprise penetration, collaborations with leading vendors and strong balance sheet will aid the stock to sustain momentum. Further, the ongoing restructuring and investments on product development along with sales execution are positives, in our view. However, declining perpetual license revenues will hurt top-line growth at least in the near term. Moreover, weakness in Europe and adverse foreign currency exchange rates are other major concerns.”

ARRIS International PLC (NASDAQ:ARRS) was upgraded by analysts at Zacks Investment Research from a hold rating to a buy rating. Zacks Investment Research currently has $32.00 price target on the stock. According to Zacks, “ARRIS reported better than expected earnings in the second quarter of 2017. We expect the company to perform well on the bottom line front in the third quarter too driven by its strong product portfolio. The company  expects earnings (adjusted) in the band of $0.66–$0.71 in the third quarter of 2017. ARRIS has recenty inked several deals to broaden its product portfolio. In Feb 2017, ARRIS entered into a deal with Broadcom to purchase Brocade Communication's Ruckus Wireless and ICX Switch units. The deal is expected to close by year-end. We are also impressed by the company's efforts to reward shareholders through buybacks. However, foreign exchange fluctuations remain a concern for the company. Moreover, the company reported lower-than-expected revenues in the second quarter. Shares of the company have underperformed its industry so far this year.”

Allegheny Technologies (NYSE:ATI) was upgraded by analysts at Zacks Investment Research from a sell rating to a hold rating. According to Zacks, “Allegheny swung to a profit in second-quarter 2017, supported by higher sales across the board. Both earnings and sales beat the respective Zacks Consensus Estimate. Allegheny should benefit from its diversified global growth markets as well as cost reduction and restructuring measures. The company is seeing healthy demand from aerospace OEMs which should spur growth. However, Allegheny has underperformed the industry it belongs to over the past six months. Allegheny remains exposed to certain challenges in its core Flat Rolled Products segment including weakness across some major end-use markets. Depressed oil prices are also expected to hurt demand for Allegheny's products in the oil and gas market in the short haul.”

Banco Bilbao Vizcaya Argentaria (BME:BBVA) had its sell rating reaffirmed by analysts at Citigroup Inc..

Bodycote PLC (LON:BOY) had its buy rating reissued by analysts at Deutsche Bank AG. The firm currently has a GBX 880 ($11.61) target price on the stock.

EOG Resources (NYSE:EOG) was upgraded by analysts at Zacks Investment Research from a sell rating to a hold rating. According to Zacks, “EOG Resources holds premium acreages in three prospective oil plays in the U.S. – the Permian, Bakken and Eagle Ford shale plays. For 2017, the firm plans to complete 480 wells in those resources, higher than 445 recorded in 2016. During 2016, almost 50% of the wells drilled by the firm met the standard of premium wells. The company now expects 80% and 90% of the wells to meet the standards in 2017 and 2018, respectively. Also, in the promising U.S. shale plays, EOG Resources has identified 7,200 premium wells that can give it access to almost 6.5 billion barrels of oil equivalent estimated potential reserves over a period of 10 years. However, excessive dependence on the North American shale plays and rising long-term debt over the last two years raise concerns.”

GKN plc (LON:GKN) had its buy rating reiterated by analysts at Deutsche Bank AG. The firm currently has a GBX 395 ($5.21) price target on the stock.

IMI plc (LON:IMI) had its hold rating reiterated by analysts at Deutsche Bank AG. Deutsche Bank AG currently has a GBX 1,170 ($15.43) target price on the stock.

Kemet Corporation (NYSE:KEM) had its hold rating reiterated by analysts at Stifel Nicolaus.

Macquarie started coverage on shares of Kosmos Energy (NYSE:KOS). They issued an outperform rating on the stock.

Level 3 Communications (NYSE:LVLT) was upgraded by analysts at Zacks Investment Research from a sell rating to a hold rating. According to Zacks, “Level 3 Communications posted strong second-quarter 2017 financial results where the company’s bottom and top line beat the Zacks Consensus Estimate.  Recently, CenturyLink and Level 3 Communications moved further closer to their proposed merger amid approval from 23 states and territories. Further, Level 3 Communications continues to have a strong presence in fields of enterprise networking including data networks, content distribution, managed services, securities, voice cloud and cloud connection. However, we remain concerned about the company’s operation in a competitive enterprise communications market. Moreover, customer concentration, foreign currency exchange rate risks and global macro economic fluctuations act as major dampeners for the company’s growth prospects. Over the past six months, share price of Level 3 Communications declined 0.30% but failed to beat the industry’s growth of 6.46%.”

Lexicon Pharmaceuticals (NASDAQ:LXRX) had its ourperform rating reiterated by analysts at Wedbush. The firm currently has a $39.00 target price on the stock.

Marston's PLC (LON:MARS) had its buy rating reaffirmed by analysts at Shore Capital.

Marathon Petroleum Corporation (NYSE:MPC) was upgraded by analysts at Zacks Investment Research from a sell rating to a hold rating. According to Zacks, “Marathon Petroleum's scale advantage, impressive asset quality and extensive midstream/retail network have helped the company to overcome the challenging market conditions. As a reflection, the downstream operator has handily outperformed the broader industry over the past 6 months- and 1-year periods. Further, management's positive update on asset dropdowns highlights MPC’s commitment to return more value to shareholders. However, the Findlay-headquartered company’s 'Refining’ segment – the main contributor to Marathon Petroleum earnings – has been weighed down by depressed margins. To make matters worse, the downstream operator saw an upswing in product cost that was reflected in higher total expenses. Last but not the least, the U.S. refiners are feeling the pinch of higher RFS costs to comply with new cleaner gasoline production rules. These factors form the basis of our cautious stance on MPC.”

MyoKardia (NASDAQ:MYOK) had its outperform rating reaffirmed by analysts at Wells Fargo & Company. They currently have a $48.00 price target on the stock, up from their previous price target of $31.00.

Regulus Therapeutics (NASDAQ:RGLS) had its ourperform rating reaffirmed by analysts at Wedbush. The firm currently has a $4.00 price target on the stock.

Renishaw plc (LON:RSW) had its sell rating reaffirmed by analysts at Deutsche Bank AG. Deutsche Bank AG currently has a GBX 3,180 ($41.95) price target on the stock.

Banco Santander, (BME:SAN) had its neutral rating reaffirmed by analysts at Citigroup Inc..

Spirit Airlines (NASDAQ:SAVE) was upgraded by analysts at Zacks Investment Research from a sell rating to a hold rating. According to Zacks, “Spirit Airlines reported better than expected earnings in the second quarter of 2017. Moreover, earnings improved 2.7% year over year. Revenues improved 20.1% during the quarter. The carrier's efforts to modernize its fleet raise optimism. During the second quarter, the carrier took delivery of three new A320ceo aircraft and one new A321ceo aircraft. The company’s efforts to reward stockholders through share buybacks are also impressive. However, the carrier reported lower than expected revenues during second-quarter 2017. Due to the pilot related dispute the carrier had to cancel multiple flights resulting in customer dissatisfaction. The costs associated with the flight cancellations hurt its second quarter results.  Moreover, the company issued a lackluster unit revenue guidance for the third quarter. Owing to the headwinds, shares of the company have underperformed its industry over the last one month.”

SunPower Corporation (NASDAQ:SPWR) was upgraded by analysts at Zacks Investment Research from a hold rating to a buy rating. Zacks Investment Research currently has $10.00 price target on the stock. According to Zacks, “SunPower’s second-quarter 2017 loss was narrower than the Zacks Consensus Estimate. Revenues declined year over year but surpassed the consensus mark. The company also narrowed its revenue guidance for 2017. On a brighter note, SunPower is gradually shifting its revenue base from solar panel sales to the development of solar projects, power plants and engineering, procurement and construction (EPC) systems. Meanwhile, it remains committed to provide high-performance solar power products to its customers. In the overseas, the company has plans to build six projects in many regions in Mexico with expected delivery dates of 2018 and 2019, and gross margin above 20%. However, rising cost is a major headwind for SunPower, given the constant need to come up with new and innovative technology. Notably, the company lost more than the broader industry’s loss during the last one year.”

Spectris plc (LON:SXS) had its buy rating reaffirmed by analysts at Deutsche Bank AG. The firm currently has a GBX 2,860 ($37.73) target price on the stock.
