Currently, both are underperformers. My short term view on both entities is Bearish, and moreso on BHEL because PSUs, due to poor governance, have lost the sheen with investors.
LnT, too, has taken on huge amount of debt, at servicing it takes a big chunk out its profits. This is significantly arresting its EPS growth. As a result, BHEL and LnT are likely to lead the fall when Nifty corrects.
