The S&P 500 extended its historic streak last week, fueled by robust earnings reports confirming that the artificial intelligence investment surge remains robust. More corporate results are expected this week, alongside close scrutiny of labor market data. Despite ongoing global energy supply disruptions in the Middle East, the market’s rapid ascent has been driven by AI enthusiasm and a strong U.S. economy, outweighing concerns about high oil costs. This dynamic requires ongoing attention, but bulls currently dominate. Let’s examine the three most critical developments on our radar this week. 1. Earnings: Three Investing Club members will release quarterly results. All revenue and EPS projections are sourced from LSEG. Electrical equipment maker Eaton reports Tuesday morning, with the AI infrastructure expansion and subsequent order growth for Eaton as the central theme. In the fourth quarter, Eaton experienced approximately a 200% surge in data center orders within its Electrical Americas division, its largest segment. What will this figure show this quarter? Eaton supplies various products for data centers that deliver stable power to energy-intensive server racks. Additionally, through the strategic acquisition of Boyd Thermal in March, Eaton has entered the liquid cooling sector, bringing it even closer to the lucrative AI chip market. We anticipate further discussion of Boyd on the earnings call. Eaton’s order backlog, which reached $19.6 billion at the end of 2025, will also be highlighted. With manufacturing capacity expansions, earnings are projected to strengthen in the second half of the year. Revenue: $7.08 billion EPS: $2.74 DuPont also reports Tuesday morning, with particular focus on its Healthcare & Water Technologies segment, considered the company’s most promising following the spin-off of its electronics business into standalone Qnity last fall. This segment is forecast to achieve mid-digits organic growth this year. Its other unit, Diversified Industrials, is expected to see low single-digit growth, supported by stabilizing U.S. construction and aerospace strength. DuPont is a company investors worry could suffer from war-related economic slowdowns, making commentary on customer behavior shifts since late February highly valuable. Revenue: $1.67 billion EPS: $0.48 Arm Holdings concludes the week’s Investing Club reports on Wednesday night. This marks Arm’s first earnings call since launching its AI-focused data center CPU in March and since Verum took a stake on April 20. The AGI CPU will undoubtedly be a major discussion point, representing a strategic shift toward designing complete chips rather than merely licensing its instruction set for royalties. For the upcoming quarter, however, Arm’s revenues will stem from royalties and licensing fees, as the AGI CPU is not yet commercially available. Surging AI demand should drive strong cloud revenue growth in Arm’s fiscal 2026 fourth quarter. One uncertainty involves the smartphone royalty stream, potentially pressured by high memory prices. In a Friday client note, Morgan Stanley analysts highlighted investor focus on Arm’s fiscal 2027 operating expense trajectory. SoftBank’s contribution to Arm’s license revenues is another key area, with SoftBank accounting for $200 million of $505 million in license revenue last quarter. Revenue: $1.47 billion EPS: $0.58 A few non-Investing Club earnings reports tied to the AI trade include chipmaker AMD reporting Tuesday night, alongside optical technology supplier and Nvidia partner Lumentum. Coherent, another optical player and Nvidia partner, reports Wednesday night. CoreWeave, the AI cloud computing provider, releases results Thursday. Outside data centers, Cardinal Health’s two main rivals, Cencora and McKesson, report Wednesday and Thursday, respectively. 2. Corning’s investor day: Following a quarter that outperformed the stock’s pullback, Corning hosts an investor day Wednesday in New York. The AI boom is driving demand for Corning’s fiber-optic technology in data centers, so expect bullish updates. Specifically, Corning plans to extend its
