MUMBAI [NCRBuzz Wire] — India’s top 10 listed blue-chip companies are experiencing a pronounced contraction in their market capitalization share, dropping to approximately 17.65% as of October 9, the lowest threshold observed since 2017. **Sustained foreign portfolio investor (FPI) selling alongside significant large-cap stock underperformance has systematically eroded the dominance of heavyweight equities on domestic bourses.**

**Foreign institutional capital outflows from premier large-cap counters have redirected investor focus toward broader market segments.** Despite the valuation compression among mega-cap firms, domestic institutional flows remain resilient, cushioning the secondary indices and propelling mid-cap and small-cap segments to outperform large-cap counterparts.
