NEW DELHI [NCRBuzz Wire] — **The Indian benchmark indices experienced a significant downward correction during the trading session, driven by aggressive institutional selling and macroeconomic headwinds.** BSE Sensex plummeted by over 500 points, while the NSE Nifty breached key technical support to trade below the 22,400 threshold. Market participants remained cautious as persistent capital outflows by Foreign Institutional Investors (FIIs) combined with rising global bond yields to depress equity valuations.

### Sectoral Impact and Market Breadth

**Tech Mahindra led the sectoral losses among major constituents, recording a sharp decline of nearly 4% amid broader profit-booking in IT heavyweights.** Despite the heavy losses in frontline indices, the broader market segments displayed notable resilience. The Nifty Midcap 100 and Nifty Smallcap 100 indices managed to buck the broader downtrend, reflecting selective buying interest in mid-tier and small-tier companies.
