The pandemic has been tough on companies in the telecommunications, airline, and oil and gas sectors. Even blue-chip stocks have not been spared. Faced with falling demand amid movement restrictions, these companies have reported declining revenue and earnings in 2020. However, economic conditions are improving and the outlook has become brighter. These same businesses could see a rebound in revenue and profit as the recovery gains momentum. Here are four blue-chip stocks that could possibly turn around in 2022. Keppel Corporation Limited (SGX: BN4) Keppel Corporation is an offshore and marine conglomerate with four distinct divisions — energy and environment, urban development, connectivity, and asset management.

In May 2020, the group came up with its Vision 2030 with plans to actively develop and invest in new growth engines.
