Grid Dynamics shares fall 15.86% after-hours as sector-wide fears of IT services slowdown follow Gartner's weak Q4 results.

Grid Dynamics surged 15.86% in after-hours trading following the announcement of a new AWS GenAI partnership and an expansion plan. The stock's sharp rebound aligns with the news summary indicating a significant deal and strategic growth initiatives, which likely bolstered investor confidence in the company’s AI-driven consulting services. This positive development contrasts with earlier bearish sentiment driven by sector-wide concerns over IT services growth, as highlighted in prior reports. The recent news appears to have directly influenced the stock’s post-market rally, signaling renewed optimism about Grid Dynamics’ business prospects.
