The stock is listed on the New York Stock Exchange as an American Depository Receipt (ADR), which means investors in the U.S. can buy Tata shares without having to open an Indian investment account or worry about exchange rates.
Tata made headlines recently when it unveiled the world's cheapest car, the Nano, which sells for as low as $2,500. With the Nano, Tata could tap into the rapidly growing market of middle-class buyers in emerging economies like India and China.
Also, Tata has a number of promising acquisitions and partnerships in the works. Tata is in talks with Ford to buy the American carmaker's Jaguar and Land Rover brands. And the company's manufacturing subsidiary recently signed a deal to produce parts for Boeing's 787 Dreamliner.
