All times ET. 6:24 a.m.: RBC lifts rating for Ball Corporation as company refocuses on core business segments RBC Capital Markets’ sees a bright future for Ball Corp . The bank upgraded shares to outperform from sector perform, also lifting its price target to $74 from $61. This corresponds to a potential 19% upside for the stock. Shares of Ball Corp have risen 8% this year. The company is best known for its production of items used in canning, such as glass jars and lids. Analyst Arun Viswanathan highlighted Ball’s commitment to its core business as a reason for the upgrade. “We upgrade BALL to Outperform from Sector Perform following its completed sale of its Aerospace business to BAE Systems for ~$4.5B net after-tax cash proceeds, of which ~$2B will be used for debt paydown and ~$2B will be used for share buybacks,” he wrote. The fundamental backdrop for global beverage can demand also looks favorable for Ball. Additionally, the company stands to benefit from improving volumes through 2024 and 2025, lower share count and balance sheet leverage, as well as higher margins from improved business execution. “We see more opportunities for margin expansion from BALL’s footprint optimization actions, esp the shutdown of higher cost, older facilities. We believe BALL has executed well in 2023 and is recovering profitability through pricing/mix, footprint rationalization and optimization, and productivity efforts,” Viswanathan added. — Lisa Kailai Han 6:05 a.m.: Rosenblatt sets highest price target on Wall Street for Super Micro Computer There’s even more AI-induced tailwinds ahead for Super Micro Computer , according to Rosenblatt. The investment firm kept its buy rating on the technology stock but nearly doubled its price target to $1,300 from $700. This is a whopping 62% from where the stock closed on Friday and marks the highest price target on Wall Street for shares of Super Micro Computer. Analyst Hans Mosesmann listed the continued momentum in artificial intelligence — and the company’s “strategic position” within the market — as a prime catalyst for the change. “Key to the story is for investors to consider that the company is benefiting not only from secular AI growth (over 50% CAGR over next several years), but material share gains. We anticipate these gains to reach double digits in the next couple of years, up from the current mid-single digits, with a particular focus on enterprise,” he wrote. However, Mosesmann stressed that a “pivotal factor” for the company remains the adoption of liquid cooling technology, which would help mitigate the challenges that come with scaling up cloud computing. Shares of Super Micro Computer have already rallied an eye-watering 183% this year. SMCI YTD mountain SMCI in 2024 — Lisa Kailai Han 5:45 a.m.: Deutsche Bank upgrades JetBlue as domestic airline backdrop improves More balanced domestic supply should spell good things for JetBlue, according to Deutsche Bank. Analyst Michael Linenberg upgraded the airline to buy from hold. He also more than doubled his target price to $9 from $4, implying that JetBlue stock could rally 29% from its Friday closing price. “We believe more moderate domestic ASM (available seat mile) growth for 2024 will have positive implications for domestic unit revenue performance, and by extension, should translate into solid top-line performance for the domestic-focused names,” the analyst wrote. Specifically, an idiosyncratic catalyst for JetBlue is the company’s near-term commitment to restoring its profitability. Although JetBlue’s blocked merger with Spirit Airlines is an obstacle, Linenberg believes the airline can still utilize other methods to grow its network. “We don’t see any impediments to JetBlue seeking alternative means to expand its network and increase market relevance and ubiquity (assuming that the Spirit merger is no longer an option) via asset-light approaches such as code shares, alliances, and/ or international joint ventures, all of which can be highly accretive to [return on invested capital] and [earnings per share],” he wrote. — Lisa Kailai Han 5:38 a.m.: Southwest Airlines receives a tepid upgrade from Bernstein Near-term demand is strong enough to outweigh the headwinds for Southwest Airlines , according to Bernstein. The investment firm upgraded the airline stock to market-perform from underperform, boosting its price target to $32 from $26. To be sure, that forecast points to a more than 5% slide from Friday’s close. Southwest has rallied 17.5% this year. Analyst David Vernon listed a stronger domestic market as a reason for the rating boost. While costs have remained elevated, demand is robust enough to balance them out. “The rejection of the JetBlue-Spirit deal and equipment availability issues at Spirit, a pivot by Frontier to shift capacity out of competitive markets, and slowing deliveries of Boeing Max aircraft has resulted in a more moderate capacity forecast than we had been expecting,” he wrote. “At the same time, travel demand remains resilient. The combination of these factors has the market believing unit revenue forecasts are too low and will be sufficient to drive positive revisions.” The analyst added that while the airline will find it difficult to raise returns on capital back to where they were before the pandemic, he’s “not as convinced the market will care near term.” Still, he cautioned that Southwest’s lofty valuation makes it especially sensitive to any potential sentiment shift within domestic pricing. — Lisa Kailai Han 5:38 a.m.: Evercore ISI downgrades Caterpillar It’s time to book some profits in Caterpillar , according to Evercore ISI. Analyst David Raso downgraded the industrial machinery giant to inline from outperform. His price target of $338 per share implies upside of just 5% from Friday’s close. “Valuations/Expectations Have Gone From ‘Survival’ To Avoiding A Down Year To Now Anticipating Reacceleration 2H24 Through ’25 & , In Many Cases, ’26,” Raso wrote. “Let’s Take Some Profits, Pause and Let EPS, Mgn Assuredness, & Macro Visibility “Grow Into The Stocks”; This Could Be ‘Not Goodbye, But Until We Meet Again.'” Caterpillar shares are off to a strong start for the year, rising 8.8%. Over the past year, the stock is up nearly 30%. CAT 1Y mountain CAT in past 12 months — Fred Imbert
