After a long time, the tide has turned for infrastructure stocks. There's massive capex lined up backed by government's announcements on the production linked incentive (PLI) schemes.
Given that facilities such as roads, railways, metros, etc. are an integral part of enhancing the productivity and operations of businesses, robust infrastructure is a must.
With a steadily rising population, the economy needs a massive amount of spending on constructing new infrastructure and rebuilding the aging assets to meet the needs.
So yes, investing in the infra sector for the long term can turn out to be a good investment.
