Hyderabad-based small-cap IT stock Blue Cloud Softech surged 16% on Monday after investors mistakenly linked its US arm’s $150-million (₹1,430-crore) statement of work with SpaceX International to Elon Musk’s SpaceX. Under the deal, Blue Cloud will build and operate an AI compute and data-centre platform for SpaceX International. A similar confusion-driven rally occurred in June following talks.
