Stocks making the biggest moves midday: American Airlines, Coherent, SLB, Tesla & more

American Airlines shares rose 6.9% midday as travel stocks gained on oil sliding after U.S.-Iran talks report.

Likely to remain supported while oil declines and the U.S.-Iran talks narrative persists; reversals possible if oil rebounds.

The article attributes the move to a broad travel-group reaction tied to oil and geopolitical headlines, not to a new AAL-specific disclosure.

United Airlines shares rose 4.3% midday alongside travel stocks as oil prices slid on renewed U.S.-Iran talks report.

Near-term upside bias while oil stays soft; sensitivity to any reversal in the oil/geopolitics catalyst.

The catalyst described is external and group-level, so stock-specific follow-through is less certain.

Coherent dropped roughly 7% midday as investors pulled back from data center infrastructure on continued hyperscaler AI spending concerns.

Potential for further weakness if the market extends the hyperscaler-spend de-risking; could rebound on any countervailing guidance.

The move is attributed to ongoing industry spending concerns rather than a new COHR-specific event.

Tesla slid more than 3% for a third day, with the stock heading for nearly a 19% weekly decline after signaling higher AI spending.

The article explicitly connects the multi-day drop to the prior signal of higher AI spending, making the catalyst coherent and time-relevant.

The article cites a specific EPS beat ($1.81 vs $1.48) and reaffirmed outlook, which are actionable fundamentals.

Digital Realty Trust surged 15% after Q2 earnings and revenue beats and a hike to full-year earnings guidance.

The article includes both beats and explicit full-year guidance increase, a strong decision-grade catalyst.
