Reuters Market Eye - Tata Motors shares slumped 5 percent on Friday, marking the biggest single-day fall since Jan. 27.
Tata unit Jaguar Land Rover (JLR) reduces prices of three models sold in China.
Price cuts are in response to a probe in China's auto industry, JLR China said.
Analysts say price cuts are a concern given the importance of profitability in China for JLR's overall margins.
