Notable movers

Edison International (EIX) -23.07%

California wildfire-liability legislation omitted reforms investors had expected to limit publicly traded utilities' exposure, prompting analyst downgrades and a severe utility selloff. The session's standout large-cap collapse erased roughly one-quarter of the utility's equity value and highlighted renewed California wildfire-liability risk.

PG&E Corporation (PCG) -20.06%

California lawmakers failed to deliver anticipated wildfire-liability protections for investor-owned utilities, leaving PG&E exposed to concerns about future claims and the adequacy of the state's wildfire fund. PG&E lost one-fifth of its value on exceptionally heavy volume, showing that wildfire liability remains a major equity risk despite the company's post-bankruptcy restructuring.

Aon plc (AON) -9.53%

Aon agreed to acquire insurance brokerage USI Insurance Services from KKR for approximately $17 billion, raising investor concerns about price, financing and integration risk. A near-10% decline in a normally lower-volatility insurance broker signaled substantial skepticism about one of the sector's largest recent transactions.

Amazon.com, Inc. (AMZN) -2.50%

The Wall Street Journal reported that the Federal Trade Commission and more than 20 states were preparing litigation alleging that Amazon manipulated prices paid by businesses advertising on its platform. A 2.5% decline in a multi-trillion-dollar company materially weighed on the broad market and raised regulatory risk around Amazon's high-margin advertising business.

SLB N.V. (SLB) +4.83%

SLB agreed to acquire cooling-equipment manufacturer Kelvion for $3.4 billion in cash plus assumed debt, expanding into data-center thermal management, while higher oil prices provided an additional sector tailwind. The transaction broadens SLB beyond traditional oilfield services into AI-data-center infrastructure while the stock also benefited from a geopolitical oil-price shock.

CrowdStrike Holdings, Inc. (CRWD) +5.77%

CrowdStrike opened its sold-out Fal.Con 2026 conference with multiple product and strategic-partnership announcements spanning Google Cloud, Snowflake, frontier-AI security and converged IT/operational-technology protection. The gain extended a volatile post-earnings move and showed strong investor reception for CrowdStrike's effort to broaden Falcon into a cross-cloud enterprise-security platform.

ExxonMobil Holdings Corporation (XOM) +2.71%

Oil prices surged after renewed U.S.-Iran military exchanges near the Strait of Hormuz heightened concerns about disruption to a critical global petroleum transit route. Exxon's gain represented a major positive index contribution and captured the session's sharp rotation into energy amid geopolitical and inflation risk.

Take-Two Interactive Software, Inc. (TTWO) -6.67%

Shares reversed the prior session's enthusiasm around Rockstar's extended Grand Theft Auto VI preview as continuing unauthorized leaks and speculation about the game's online rollout renewed execution concerns. The move underscored how heavily Take-Two's valuation and near-term earnings narrative depend on the November 2026 GTA VI launch.
