On this episode of Stock Movers:

- Apple (APPL) shares are still lower as investors continue to digest an earnings report that failed to soothe investor concerns about its biggest challenges, including escalating tariff costs and a slowdown in China. The company’s shares declined as much as 5.2% after markets opened in New York on Friday. Apple had released second-quarter results that included worse-than-expected sales in China. The iPhone maker also warned in the Thursday statement that tariffs will increase costs this quarter, a sign that geopolitical tensions are taking a growing toll on the world’s most valuable business.

- Block (XYZ) shares sunk as much as 24%, the most since March 2020 after the financial services and digital payments company cut its gross profit guidance for the full year. The Cash App parent company reported results that suggest weakness in the company’s efforts to convert millions of active users into full-fledged banking customers.

- Duolingo (DUOL) shares are still up after the language-learning software firm reported results that beat expectations. Sales will be $987 million to $996 million this year, the company said in a letter to shareholders, up from its previous view of at most $978.5 million and ahead of analysts’ projections for $973.2 million. Subscriptions for its highest-price tier — Duolingo Max — continued to grow in part due to the appeal of its AI-powered video call feature. Daily active users across all tiers jumped 49% to 46.6 million in the period, while the company now counts 10.3 million paying subscribers, slightly ahead of expectations.
