Dell Technologies (DELL) surged 11% after delivering strong fourth-quarter earnings that beat Wall Street expectations. The company reported revenue of $33.4 billion, significantly above the $31.41 billion consensus estimate. Even more notable, Dell issued robust long-term guidance, projecting fiscal year 2027 revenue between $138 billion and $142 billion, well ahead of analyst forecasts of $124.9 billion. The upbeat outlook fueled investor confidence and boosted Dell stock.

Block, Inc. (XYZ) rallied 23% after posting solid quarterly results and unveiling a major restructuring plan.

Duolingo (DUOL) dropped 22% after issuing forward guidance that fell short of market expectations, overshadowing its quarterly performance. Meanwhile, cybersecurity firm Zscaler (ZS) declined 7%.
