Shares of auto ancillary companies, such as Motherson Sumi, Bharat Forge, Balkrishna Industries, MM Forgings, Sundaram Fasteners and Wabco may come under pressure due to a sharp decline in the euro against the rupee. Over the last year, the euro has tumbled from a high of 83.5 to 68 a rupee. Analysts expect these firms to be hit due to cross-currency hedgings. If the euro remains weak during the rest of 2015, they may have to pass on the price hikes to customers.
