Palo Alto Networks, Inc. (PANW) -9.28%

Shares sold off in the first regular session after Palo Alto Networks reported quarterly results. The results exceeded Wall Street expectations, making the negative price reaction especially notable. A sharp post-earnings reversal in a mega-cap cybersecurity leader pressured peers and highlighted demanding expectations embedded in security-software valuations.

NVIDIA Corporation (NVDA) +3.21%

Nvidia rallied amid continued AI-infrastructure enthusiasm and reports that it was in talks to acquire AI-model platform Hugging Face. Although smaller in percentage terms than several mid-cap moves, Nvidia's enormous capitalization made it one of the session's most consequential index drivers.

Palantir Technologies Inc. (PLTR) -5.81%

Palantir declined during a broad selloff in richly valued software and services stocks exposed to shifting perceptions of AI disruption and competitive risk. The fall in one of the market's largest AI-software winners was a conspicuous divergence from gains in AI-hardware leaders such as Nvidia and Dell.

Datadog, Inc. (DDOG) -6.53%

Datadog fell with software and services companies as investors continued to reassess potential AI disruption and elevated valuations. The decline extended a two-session drawdown in a high-growth observability leader and showed that AI enthusiasm was producing clear winners and losers within software.

Fortinet, Inc. (FTNT) -4.52%

Fortinet declined with cybersecurity and software peers following Palo Alto Networks' negative post-earnings reaction and broader concern about AI disruption in software and services. The sympathy move showed how quickly a disappointing reaction in one security leader propagated across a high-valuation cybersecurity group.

Steel Dynamics, Inc. (STLD) +5.79%

Steel Dynamics participated in a broad steel and materials rally. Materials was the best-performing S&P 500 sector during the session. A large move in a liquid domestic steel producer reinforced the day's rotation toward cyclicals and tariff-sensitive materials companies.

Nucor Corporation (NUE) +4.78%

Nucor led a broad advance in steel and materials stocks as materials finished as the strongest S&P 500 sector. The move in the largest U.S. steelmaker was an important cyclical and tariff-policy signal rather than an isolated small-cap materials spike.
