The Nifty Auto index plunged over 6% on Monday, led by a sharp decline in Bharat Forge shares, which fell by 10%.
JP Morgan's report highlighted the potential earnings impact on Indian auto suppliers following the recent imposition of a 25% tariff on automobiles and parts by the US.
The report identified Samvardhana Motherson International, Bharat Forge, and Sona Comstar as the most affected under JP Morgan's coverage.
Indian suppliers, however, have strong balance sheets and should be able to mitigate the impact through capacity investments and acquisitions of smaller suppliers over time.
