Shares of Indian technology companies Sterlite Technologies Ltd and MTAR Technologies saw significant declines on Wednesday, November 4, 2026, with both stocks losing as much as 5% of their value. The market reaction stemmed from investor worries about potential stricter regulation of the artificial intelligence (AI) sector following a Democratic victory in the recent US midterm elections.
Sterlite Technologies, a key player in physical infrastructure, saw its shares hit a two-month low. The company's business relies heavily on the development of data centers, which could be slowed by increased oversight of the AI industry. The stock, which had previously shown strong gains in 2026 and over the past year, traded lower than its short-term moving averages, though it remained above longer-term trends.
Impact on MTAR Technologies
MTAR Technologies, a supplier of crucial fuel-cell components to Bloom Energy—a company that powers AI data centers—also experienced a sharp decline. Its stock slipped to a low of Rs 6000.50 from its previous close of Rs 6310.85, causing the firm's market capitalization to fall to Rs 18,548 crore. Like Sterlite Technologies, MTAR's performance is directly linked to the health and growth trajectory of the AI data center ecosystem, making it vulnerable to regulatory changes.
Market Reaction and Outlook
The shared downturn highlights how closely the Indian tech market, particularly companies supporting digital infrastructure, is watching international political and regulatory developments impacting the global AI sector. While Sterlite Technologies managed to erase some losses later in the day, trading 3.41% higher at Rs 784.80 in the afternoon session, the initial sharp drop underscores prevailing investor caution regarding the future regulatory environment for AI.
