Sterlite Tech shares slide 5% after rallying 56% in one month. Here’s why

Shares of the company remained locked in the lower circuit at Rs 588.30 apiece on NSE in the morning trading hours of Monday.

South Korea’s Kospi plunged 9% on Monday morning, leading to a 20-minute trading halt, as the massive selloff in tech stocks raged on. The index is now down about 14% from the record high it touched last week. The sharp downturn came after heavyweights and semiconductor stocks tumbled, including Samsung shares which crashed over 6%.

The sharp plunge in Kospi reflects the sharp pause in the AI rally, as too much of the benchmark index’s earlier momentum had become tied to the performance of a small group of AI-linked stocks. Samsung Electronics and SK Hynix together account for nearly half of the KOSPI’s weighting and have contributed roughly two-thirds of the benchmark’s gains this year.

Sterlite, the optical-fiber maker owned by the Vedanta Group, was seen as the “poster child” for the AI boom. This came amid expectations that the world’s AI expansion needs massive amounts of high-speed connectivity infrastructure, and optical fibre is becoming the backbone of that ecosystem.

The company late in May announced that its subsidiary has secured a multi-year supply agreement valued at $1.11 billion from a global hyperscaler for AI-ready data centre infrastructure projects in the US. Hong Kong-based CLSA had said that this significantly strengthens Sterlite’s positioning in AI data centres while improving medium-term growth visibility. It expected the order to reinforce Sterlite’s competitiveness in global markets, while maintaining an “Outperform” rating on the stock.

However, the sharp crash in tech stocks led to rising worries that the AI rally was fizzling out, which may have led to the downtrend in Sterlite Tech shares today.
