Stocks making the biggest moves midday: Coty, Paramount Skydance, Walmart and more

Coty shares plummeted over 20% in midday trading, driven by a significant earnings per share miss and a weak fiscal H1 2026 forecast, despite beating revenue expectations. Conversely, Paramount Skydance surged 15% on better-than-expected Q2 earnings and an unexpected streaming profit, while Xpeng jumped over 14% following CEO share purchases and improved Q2 financials. Walmart slipped over 4% as an EPS miss overshadowed a revenue beat and raised full-year outlook, with the retailer noting rising tariff costs. Other notable movers included Nordson rallying over 5% on strong results and guidance, and Hewlett Packard Enterprise and Broadstone Net Lease gaining on analyst upgrades.

Analysis

Midday trading revealed significant divergence in corporate performance, heavily influenced by earnings results, corporate guidance, and analyst actions. Coty experienced a steep decline of over 20% after its quarterly report showed a loss of 5 cents per share, a stark contrast to the 2 cents profit analysts expected, which completely overshadowed a revenue beat of $1.25 billion. The company's weak forecast for the first half of fiscal 2026 further amplified investor concerns. Conversely, Paramount Skydance surged 15%, driven by better-than-expected Q2 earnings and a notable, unexpected profit in its streaming division. Similarly, Xpeng's U.S. shares gained over 14% on dual catalysts: a CEO purchase of 3.1 million shares and a strong Q2 report with above-consensus revenue and a narrower-than-expected loss. In the retail sector, Walmart shares fell over 4% despite beating revenue estimates and raising its full-year outlook; an adjusted EPS of 68 cents missed the 74-cent consensus, and the company highlighted rising costs from tariffs, signaling margin pressure. Other notable movements included Nordson's 5% rally on strong earnings and an improved sales outlook, while analyst upgrades drove gains for Hewlett Packard Enterprise (+3% from Morgan Stanley) and Broadstone Net Lease (+2% from Goldman Sachs). Conversely, a Wedbush downgrade citing competition pushed Maplebear (Instacart) down 2%.

Key Decisions for Investors

• Given Coty's significant earnings miss and weak near-term forecast, investors should treat its promise of a second-half 2026 turnaround with caution, as the market is clearly prioritizing current profitability over future product launches.
• The combination of a strong quarterly report and a substantial insider share purchase by Xpeng's CEO provides a strong bullish signal, suggesting high internal confidence that could warrant a closer look for growth-oriented investors.
• For Walmart, the negative stock reaction despite a raised outlook indicates that the market is highly sensitive to margin erosion; investors should carefully monitor the impact of tariffs on the company's profitability in upcoming quarters.
• Paramount's unexpected streaming profit represents a potential inflection point, and investors should evaluate whether this signals a sustainable shift in the division's economics that could justify its recent 25% monthly gain.
• The sharp stock moves in HPE and Broadstone Net Lease following analyst upgrades underscore the importance of monitoring Street sentiment as a potential short-term catalyst, especially ahead of anticipated corporate events like HPE's upcoming earnings.
