Motherson Sumi Wiring Share Price Jump 10% on Greenfield Expansion and GST Optimism

On August 19, 2025, Motherson Sumi Wiring India share price surged 9.98% to ₹43.40 during intraday trade on NSE before cooling to ₹41.39 by 2:04 PM, still up nearly 5%. The stock saw heavy trading volumes, with almost 33.89 million shares worth ₹144 crore changing hands.

Why the Rally?

There is strong growth potential from 3 greenfield projects with combined revenue opportunities of ₹2,100 crore.

• Pune and Navagam plants have already started operations.
• The Kharkhauda plant is expected to go live in Q2 FY26.
• These plants supply wiring harnesses to Maruti Suzuki, Tata Motors, and Mahindra & Mahindra.

The projects are tied to new vehicle launches, ensuring clear demand visibility and reducing execution risks.

Sector-wide Boost from GST Reforms

Apart from company-specific drivers, the stock also benefited from a broader rally in auto stocks, with the Nifty Auto index up 1.22%. Investor sentiment strengthened after PM Modi announced plans to simplify GST slabs, which could reduce costs for manufacturers and benefit consumers.
