Tenneco surges after Barclays sees emissions-control growth

Tenneco Inc. rose as much as 16 percent after Barclays Capital said earnings in 2012 may be higher than previously expected because of growth in the commercial diesel emissions control market.

Profit in 2012 may be as much as $4.60 a share, up from a previous estimate of $3.25, Brian Johnson, a Barclays analyst, said today in a report. Tenneco may be able to produce its emissions equipment for larger trucks without adding additional plants in North America or Europe, Johnson said.

Lake Forest-based Tenneco rose $2.57, or 13 percent, to $22.55 at 11:40 a.m., after earlier climbing as high as $23.12.
