Indian shares dove Thursday on investor fear that rising crude oil and higher domestic inflation will grind the world's second-fastest growing economy to a halt. Traders said the consensus among the investing community is that a rate hike is almost inevitable with the current levels of inflation."Market sentiment is playing a crucial role in determining the stock prices. Shipping and commodities are the only two sectors faring well at this stage," said Arpit Aggarwal, head of research at Arihant Capital. The Bombay Stock Exchange's Sensex Index lost 336 points, or 1.9%, to 16,907. Here's a look at how some India-based American depositary shares traded in the U.S. Thursday.
