Stocks in India crashed on Monday to their lowest level of the year on heightened concerns over skyrocketing crude oil prices and fears of uncontrollable inflation. Market observers in the Far East said that traders reacted to the super spike of $10 in crude oil prices and the disappointing U.S. unemployment report that helped take the Dow down 400 points on Friday. The Sensex Index dove past the psychologically important level of 15,000 before rebounding to close slightly above the key mark.Market players are worried that inflation, which is already running at 8%, is spiraling out of control after the government initiated fuel price hikes last week. "Investors are panicky about the overall market scenario as they feel there might be further rise in inflation. It will take some time for the market to adjust to the emerging global economic scenario due to the rise in crude oil prices," said S.P. Tulsian, financial analyst and CEO of Tulsian.com. The Bombay Stock Exchange's Sensex Index plunged 505 points, or 3.2%, to 15,066.10 Here's a look at how some India-based American depositary shares traded in the U.S. on Monday.
