Shares of United Commercial Bank today fell 3.5 per cent on worries that October-December results, due later in the day, would show an increase in bad loans.

Gross non-performing loans may rise to 6.35 per cent of advances, say analysts.

Quarterly profit is seen at Rs 310 crore vs expectation of Rs 500 crore, dealers say.

Rising bad loans at ICICI Bank, Punjab National Bank and Bank of Baroda are also leading to paring of positions in the sector.
