Whether it is upward or southward movement of Nifty or Sensex, it is largely led by financial services stocks which include banks, both private and public sector and other heavy weights which essentially are part of the financial services.

The big difference this time has been the fact that while private banks are correcting, PSU banks have been able to outperform and have provided a counter to bears. If the PSU banks start to correct, will it lead to correction in overall markets ?
