U.S. equities finished mostly lower on Thursday as investors adopted a cautious posture following the latest round of corporate earnings reports. The Dow Jones Industrial Average led the decline with a drop of nearly 1%, while the S&P 500 posted a modest loss and the Nasdaq Composite proved relatively resilient despite weakness across several technology names.

The current market environment continues to reward companies that comfortably surpass expectations while penalizing those that fall short of elevated forecasts, even in cases where quarterly results are fundamentally solid. This dynamic has become more pronounced as major indices trade near record levels, raising the bar for corporate results and leaving stocks vulnerable to sharp repricing when guidance disappoints.

U.S. Stock Indices

• Dow Jones Industrial Average: 53,890.40 (-464.05, -0.85%). At session highs, the index was up 154 points.
• S&P 500: 7,710.01 (-13.55, -0.18%). At session highs, the index was up 19.29 points.
• Nasdaq Composite: 26,348.35 (-15.09, -0.06%). At session highs, the index was up 136 points.
• Russell 2000: 3,001.57 (-17.62, -0.58%). At session highs, the index was up 13.01 points.
• Nasdaq 100: 29,373.33 (-114.46, -0.39%). At session highs, the index was up 81.96 points.

Dow's Biggest Losers

The Dow's underperformance was driven by weakness across several heavyweight components:

• Boeing (BA): -3.34%
• Salesforce (CRM): -3.20%
• Honeywell (HON): -2.95%
• Goldman Sachs (GS): -2.62%
• UnitedHealth (UNH): -2.14%

These five stocks accounted for much of the Dow's decline as investors rotated away from industrial, financial, and healthcare names. The Dow's price-weighted structure means that the largest percentage moves in its highest-priced components exert an outsized influence on the index's daily performance, amplifying the impact when multiple heavyweights sell off in tandem.

SanDisk Disappoints Despite Strong Earnings

Among the day's most notable stories was SanDisk, whose stock sold off sharply following its earnings release. Although the company reported another strong quarter, management's forward guidance failed to satisfy investors who have grown accustomed to increasingly optimistic outlooks from AI-related companies. Memory and storage providers have been among the key beneficiaries of the AI infrastructure buildout, as data center expansion drives demand for high-performance flash storage, making investor expectations for the sector especially sensitive to any hint of decelerating growth.

From a technical standpoint, the stock sustained significant damage. The earnings reaction gapped the price below both the 100-hour and 200-hour moving averages, which are now clustered near $1,360. That zone has become an important technical ceiling. As long as the stock remains below those converging moving averages, sellers retain the short-term technical advantage. A move back above that area would be required to improve the bullish outlook.

On the downside, sellers pushed the stock below the 50% retracement of the rally from the 2025 low, and buyers were unable to produce a meaningful rebound. That failure shifts the technical focus toward the 61.8% retracement near $935, which represents the next major downside target should selling pressure persist.

Looking Ahead

The broader market remains near record territory, but Thursday's session served as another reminder that expectations matter just as much as earnings. Investors continue to demand not only strong results but also stronger guidance and sustained momentum. As earnings season progresses, traders will be monitoring whether buyers can defend key technical levels in the broader indices while remaining selective in individual stock opportunities.
