Midday Movers Roundup — May 27, 2026

CNBC reported Wednesday that a sharp pullback in crude oil prices lifted travel stocks sharply in midday trading, even as a disappointing revenue outlook from cloud security firm Zscaler weighed on the broader cybersecurity sector.

Travel Stocks Rally on Oil Slide

Brent crude and West Texas Intermediate each fell roughly 4% on Wednesday, handing airlines and cruise operators a meaningful tailwind. United Airlines gained 7%, while Delta Air Lines rose 4%. Cruise operators joined the move higher, with Carnival and Norwegian Cruise Line each climbing roughly 4% to 5%. MGM Resorts also advanced 10% after JPMorgan upgraded the stock to overweight, citing resilience among U.S. leisure travelers and improving prospects for Las Vegas Strip revenue growth.

Zscaler Miss Pulls Cybersecurity Lower

The session’s biggest loser was Zscaler, whose shares tumbled more than 30% after the company issued current-quarter revenue guidance that fell just short of analyst expectations. Its fiscal third-quarter earnings and revenue both beat forecasts, but the forward outlook was enough to unsettle investors. The selloff spread to peers, with Palo Alto Networks and CrowdStrike each dropping roughly 3%.

Winners and Losers Across Sectors

Telecom infrastructure firm Dycom Industries surged about 30% after lifting its full-year revenue outlook and announcing an acquisition that expands its data center capabilities. Bath and Body Works rose 12% following better-than-expected second-quarter earnings guidance. Abercrombie and Fitch jumped more than 12% on a strong earnings beat, though its revenue missed slightly and near-term guidance disappointed. Micron Technology extended a recent rally after crossing the $1 trillion market cap threshold on Tuesday.

Background: A Market Sensitive to Forward Guidance

Midday sessions like Wednesday’s reflect a market that has grown acutely sensitive to forward guidance rather than past results. Zscaler’s underlying quarterly numbers were solid, yet a guidance shortfall of just a few million dollars against analyst estimates triggered a 30%-plus selloff. That dynamic has played out repeatedly in 2026 as investors price companies on what comes next rather than what just happened.

On the downside, Verra Mobility was the session’s most dramatic casualty, plunging more than 70% after Avis Budget Group terminated a major contract effective September. The company warned the loss would reduce annual commercial services revenue by $135 million to $145 million. Dick’s Sporting Goods and Insulet each fell roughly 5% to 7% on guidance concerns and a product correction notice, respectively.
