Stocks making the biggest moves midday: Home Depot, Intel, Viking Therapeutics, Nvidia and more

Tuesday's midday trading was marked by significant stock movements driven by company-specific news and broader market trends. Viking Therapeutics shares plummeted 42% following Phase 2 trial results indicating its experimental oral obesity drug had more side effects than anticipated, leading to a 20% patient dropout rate. Conversely, Intel surged over 6% on SoftBank's $2 billion investment, while Tegna climbed 4% after Nexstar Media agreed to acquire it for $3.54 billion. Additionally, Palo Alto Networks gained over 3% on strong Q4 results and guidance, even as high-flying tech stocks like Nvidia and AMD, and crypto-linked equities, saw profit-taking.

Analysis

Midday trading activity was characterized by significant dispersion, driven largely by company-specific catalysts rather than a broad market trend. On the positive side, strategic investments and M&A activity provided notable lifts, with Intel (INTC) surging over 6% following a $2 billion investment commitment from SoftBank, and Tegna (TGNA) climbing 4% on its announced $3.54 billion acquisition by Nexstar. Strong corporate fundamentals also fueled gains, as Palo Alto Networks (PANW) rose over 3% on beating Q4 expectations and issuing robust forward guidance, while Xpeng (XPEV) gained 5% after reporting a narrower-than-expected loss. Conversely, a major clinical setback sent Viking Therapeutics (VKTX) shares plummeting 42% after its oral obesity drug trial revealed a high 20% patient dropout rate due to side effects. In another sign of elevated market expectations, Fabrinet (FN) dropped 10% despite narrowly beating earnings estimates and providing upbeat guidance. Elsewhere, profit-taking was evident in recent high-performers across technology and healthcare, with Nvidia (NVDA), AMD, and Palantir (PLTR) falling between 3% and 7%, and UnitedHealth (UNH) declining over 2% after a recent Buffett-stoked rally. This rotation was mirrored in the digital asset space, where crypto-linked stocks such as Robinhood (HOOD) and Mara Holdings (MARA) fell in tandem with a 2% pullback in Bitcoin.

Key Decisions for Investors

• Re-evaluate the risk profile of Viking Therapeutics (VKTX), as the 20% patient discontinuation rate in its Phase 2 trial presents a significant commercialization hurdle for its obesity drug, potentially outweighing the efficacy data.
• Consider the strategic validation for Intel (INTC) from SoftBank's $2 billion investment and for Target Hospitality (TH) from its analyst upgrade as a 'data center play', as these catalysts may signal a fundamental re-rating.
• Distinguish between fundamentally-driven gains, like those in Palo Alto Networks (PANW) post-earnings, and technical profit-taking in high-flyers like Nvidia (NVDA), as the latter may not reflect a change in the underlying company outlook.
• For investors in Tegna (TGNA), the focus should shift to the M&A arbitrage opportunity, monitoring the progress and regulatory approvals of the Nexstar acquisition expected to close next year.
