We could see second round of sell off as 11500 is breached. On the higher side 11800 continues to be a strong resistance. We expect some volatility going forward. We expect the market to trade in the broader range of 11500-11800. Bank Nifty has strong resistance at 30,000. Bank Nifty can see some more profit booking. NBFC space continues to look pretty weak, says Vikas Jain, Sr. Research Analyst, Reliance Securities.
