Indian markets ended sharply lower as uncertainty remained over the $700 billion US bailout plan. Traders sold off positions due to lack of clarity over the US financial situation, including the postponing of a meeting between presidential candidates and the buyout of Washington Mutual by JPMorgan Chase. The Sensex index fell 445 points, or 3.28%, as realty, metal, bank and capital goods stocks declined, while only a few fast moving consumer goods stocks gained. Analysts said sentiment was negative throughout the session.
