Domestic stock markets fell after a mixed start on Tuesday tracking weakness in Asian peers amid pessimism about world economic growth. The Sensex fell as much as 193 points to touch 36,385 in morning while the Nifty hit 10,902 on the downside, 59 points below the previous close. Selling in auto, metal and energy stocks pulled the markets lower, but buying witnessed in pharma stocks kept the losses in check.
