Notable movers

Amazon.com, Inc. (AMZN) +15.32%

Amazon reported much stronger quarterly profit than expected as AWS growth accelerated, bolstering the view that its large artificial-intelligence investments are beginning to generate returns. The rally added hundreds of billions of dollars in market value and materially drove the Nasdaq and S&P 500 higher, making it the session's most consequential individual-stock move.

Apple Inc. (AAPL) -7.35%

A stronger-than-expected fiscal third quarter was overshadowed by current-quarter revenue-growth guidance below expectations and warnings that AI-driven component demand was increasing memory costs and constraining supply. The decline erased hundreds of billions of dollars in market value and showed that even positive backward-looking results could not offset concerns about forward growth and AI-related input costs.

Roblox Corporation (RBLX) -26.85%

Roblox reported a second-quarter bookings miss, projected third-quarter bookings and revenue below expectations and did not provide a full-year forecast. The largest one-day decline in the company's public-market history reset expectations for gaming engagement and monetization despite comparatively stable retention.

IES Holdings, Inc. (IESC) +30.27%

Fiscal third-quarter revenue rose 40% to approximately $1.24 billion, operating income increased 60%, backlog expanded sharply and the company announced a two-for-one stock split. A roughly 30% earnings gap in a liquid data-center and electrical-infrastructure contractor highlights continued investor demand for AI-related power and construction exposure.

Reddit, Inc. (RDDT) -20.99%

Reddit exceeded headline earnings and revenue expectations and issued strong guidance, but management's warning about choppy search referrals and slowing U.S. user-growth rates dominated the reaction. The severe decline despite a financial beat exposed investor sensitivity to Reddit's dependence on search traffic and the perceived threat from AI-generated search answers.

Eaton Corporation plc (ETN) +7.32%

Eaton rallied after its quarterly earnings update reinforced demand and profit expectations for electrical equipment and power-management products. Eaton is a major public-market proxy for data-center power demand, grid modernization and electrification, giving the earnings-driven rally significance beyond the company itself.

Coinbase Global, Inc. (COIN) -10.59%

Shares underwent a sharp post-earnings reset after Coinbase released second-quarter results; the reviewed sources did not support attributing the entire decline to one isolated metric. The move provides a liquid read-through on crypto trading activity, retail risk appetite and the market's valuation of regulated digital-asset infrastructure.

Rivian Automotive, Inc. (RIVN) -9.57%

Rivian declined following its quarterly update, although the reviewed evidence did not isolate a single downside item strongly enough to mark the catalyst as confirmed. The selloff is a useful sentiment marker for capital-intensive electric-vehicle manufacturers and expectations surrounding Rivian's next-generation vehicle ramp.
