Tenneco Clean Air India: Should you buy, sell or hold?

Analysts suggest alloted investors to book partial profits, raising caution around the auto sector’s cyclicality and reliance on OEM volumes.   Shivani Nyati, head of wealth at Swastika Investmart, said the company's strong opening was supported by investor confidence in the company's global backing, advanced clean-air and emission-control technology, and long-standing relationships with major automobile OEMs. Its diversified product range and alignment with tightening emission norms further strengthened sentiment.

 

"Despite the upbeat debut, some caution remains due to the auto sector’s cyclicality, dependence on OEM volumes, and raw-material–linked margin pressures. Allottees may consider booking partial gains and holding the rest with a stop-loss near ₹480," Nyati added.
