Updated from 5:49 p.m. EDTIndian stocks plunged Monday on fears that new accounting rules will depress fourth-quarter earnings. Traders in the Far East blamed the sharp losses on reports that the Institute of Chartered Accountants of India (ICAI) has asked companies to disclose all losses on derivative contracts for the current financial year. Market players believe the disclosure of these losses will have a large impact on fourth-quarter results "Sixty per cent of the fall in the market was due to uncertainties following the ICAI mandate that companies disclose their losses in credit derivatives which could spoil the earnings picture; inflation which could put cost pressures and reduce profits, weak global cues etc," said Rajesh Jain, director and CEO of Pranav Securities. The Bombay Stock Exchange Sensitive Index dove 726.85 points, or 4.4%, to 15,644.44, which now puts the index down 23% on the year and on track to register its worst quarterly performance.
