Check out the latest calls and chatter below. All times ET. 6:38 a.m.: Bernstein downgrades General Motors General Motors’ good luck may finally be running out, according to Bernstein. The investment firm downgraded the automobile stock to market perform from outperform and lowered its price target to $53 from $54.50. This updated target is approximately 8% higher than where shares closed on Friday. General Motors has climbed 36% this year. But analyst Daniel Roeska now sees risks to earnings and growth in shareholder distributions beginning to emerge. “Continued inventory build in the U.S. will lead to pricing headwinds next year, a delayed ramp on electric vehicles and Cruise pushes losses into next year, and headwinds in GM’s international businesses are increasing,” he said. As a result, Roeska lowered his 2025 adjusted earnings per share forecast for the stock by 7.7%. Meanwhile, General Motors’ upcoming October capital markets day could further illuminate the company’s near-term cash needs. “We are concerned that an updated EV strategy, a potential Hyundai-collaboration on hybrids, and Cruise evolution could introduce additional capital requirements and weigh on FCF,” Roeska said. “Given the risk of declining earnings in ’25e and potentially higher investment needs in the business, we see the risk balance skewed to lower FCF.” — Lisa Kailai Han 6:19 a.m.: Citi raises Meta price target Meta’s TikTok competitor Instagram Reels could be a lasting tailwind for the technology titan, according to Citi. The bank reiterated its buy rating on the “Magnificent Seven” stock while lifting its 12-month price target to $645 from $580. The updated price target implies that shares could rise another 15%. Analyst Ronald Josey pointed to rising engagement and demand in Instagram’s short-form Reels video platform as a major catalyst for the stock. “As Reels ad load and usage continue to expand we believe Meta’s discovery engine and content recommendation models, powered in part by its investments in GenAI, are a competitive advantage and represent a clear path of LLM ROI,” he wrote. “In fact, in many ways we believe Meta’s competitive advantage is now deeper and wider given improved engagement, investments in GenAI, and multiple newer offerings on-the-come.” Josey added that Meta remains his top stock pick across the internet sector. Meta stock has rallied 59% this year. META YTD mountain META year to date — Lisa Kailai Han 6:12 a.m.: Citi double upgrades Ciena to buy from sell Citi likes what it sees from Ciena . The bank double upgraded the networking systems stock to buy from sell. Analyst Atif Malik also lifted his price target to $68 from $44, which points to upside of 16%. As a catalyst, Malik pointed to an improving backdrop in the telecommunications/cable industry due to a pickup in demand and bookings. This could begin to have a material impact on the company’s returns beginning in 2025, the analyst wrote. “With measured improvement in this meaningful piece of the business, we see less risk to numbers and believe CIEN is more likely to achieve its L-T 6-8% target for topline growth,” he added. Health cloud demand will also support Ciena’s growth in 2025. While Malik sees the company as a potential beneficiary of artificial intelligence, he noted that these opportunities still seem to be further out for the company. “While we continue to believe that material AI-related opportunities for CIEN are likely 6-12 months away, once the traffic related to AI applications flows to other data centers or to consumers across the network, the positive trends in CIEN’s webscale bookings are supportive of growth in FY25 webscale revenues, in our view,” the analyst wrote. Shares of Ciena have climbed 30% this year. — Lisa Kailai Han 5:47 a.m.: Raymond James downgrades Palantir It may be time to move to the sidelines when it comes to Palantir , according to Raymond James. Citing a strong performance, the firm downgraded the software stock to market perform from outperform. Analyst Brian Gesuale also removed his price target of $30. “While we remain enthusiastic about Palantir’s longer term positioning in AI, we are downgrading our rating to Market Perform from Outperform given our view that shares need to consolidate stellar gains over the last couple of years and grow into its rich valuation,” he elaborated. “Valuation has expanded ~fivefold making it the richest software name amongst comps at 26.1x FY25 sales.” Shares of Palantir have soared 117% in 2024. PLTR YTD mountain PLTR year to date While a high valuation may be the stock’s biggest near-term obstacle, Gesuale is optimistic on the company’s potential in the long run as an artificial intelligence beneficiary. “Geopolitical instability and global AI arms race provide improving long term visibility for Palantir that should pave the way for ongoing growth in the ~20% range over the next few years,” Gesuale added. — Lisa Kailai Han 5:47 a.m.: Morgan Stanley raises Constellation Energy price target Constellation Energy’s new nuclear power deal primes the stock for strong gains ahead, according to Morgan Stanley. Analyst David Arcaro raised his price target on shares to $313 from $233. The new forecast points to nearly 23% upside. Constellation Energy on Friday announced it would restart the Unit 1 reactor at Three Mile Island, with the intention to sell that power to Microsoft for its data center needs . The stock rallied more than 22% on the news — bringing its year-to-date advance to 118%. CEG YTD mountain CEG year to date “This is an attractive deal for CEG,” Arcaro wrote. “Operational risk to bring the plant online appears manageable, the contract is very long (20yrs) and with a strong counterparty. Bringing nuclear online supports the grid, with no emissions and 24×7 operations, and the move has generated strong political support.” Wells Fargo analyst Neil Kalton also hiked his price target on the stock to $300, implying nearly 18% upside ahead. — Fred Imbert
