Stock Market Slide Erases Over ₹1,13,000 Crore From M-Cap of 7 Top Firms as Bharti Airtel Leads Decline

A weak trading week in the Indian stock market wiped out over ₹1,13,000 crore in combined market capitalization from 7 of the top 10 Sensex companies. Bharti Airtel and Reliance Industries recorded the heaviest valuation losses, even as TCS led a group of three gainers.

The domestic equity benchmark indices endured a challenging week as selling pressure dragged down seven of India's top 10 most valuable companies by market capitalization. Collective losses for these seven corporate giants exceeded ₹1,13,000 crore over the trading period. Conversely, defying the broader negative sentiment, three blue-chip firms managed to add a combined ₹21,718.47 crore to their total valuation.

Benchmark Indices Performance

During the week, equity markets experienced notable volatility before closing in negative territory. The 30-share BSE Sensex declined by 276.32 points or 0.35 per cent. Simultaneously, the broader 50-share NSE Nifty index shed 76.35 points, marking a drop of 0.31 per cent. This headline index weakness directly impacted market capitalizations across major listed entities.
