2) Covid-19 plays
Mask makers - Early in 2021 it is highly likely that President Biden will make wearing face masks compulsory in many areas within the USA. Some winners can be the mask manufacturers such as 3M Co (MMM). ZEN Graphene Solutions [TSXV: ZEN] (OTCPK:ZENYF) has developed a graphene/silver colloidal patented coating that is 99% effective against Covid-19. They recently announced a contract in Canada to supply their graphene/silver coating for 100 million masks. These masks are clearly superior to standard N95 masks with no viricidal coating. It seems quite probable that ZEN will get a lot more of these contracts in 2021.
