Indian markets are facing a volatile session on Thursday's early deals with Sensex and Nifty 50 swinging between positive and negative. Banking stocks were the major bears of today after the biggest loan fraud of nearly Rs 23,000 crore of ABG Shipyard against a consortium of banks, which shocked the sector. In the most recent development, the ED has filed a money laundering case against ABG Shipyard, its former promoters and others involved in the loan case. BSE Bankex slipped more than 445 points currently. A sell-off was seen by the FII yesterday of Rs 1890.96 crore, and buying by the DII of Rs 1180.14 crore was recorded.
