The artificial intelligence boom is no longer the exclusive domain of global technology giants. In India, it has created an unlikely set of stock market winners: optical fibre manufacturers.
No company has captured investor attention quite like Vedanta-backed (0.98% stake) Sterlite Technologies. The stock soared an astonishing 400% in 2026, making it one of the market's standout performers. The rally has also fuelled a dramatic wealth creation story, with the company's market capitalisation ballooning from just over Rs 4,000 crore at the start of the year to around Rs 27,000 crore in just six months.
