Final answer:
Multiportal competition
Step-by-step explanation:
When diversification results in two companies, such as UPS and FedEx, simultaneously competing in the same product areas or geographic markets, this is called multiportal competition.
Multiportal competition occurs when multiple companies compete in the same industry or market, offering similar products or services to customers. In this case, both UPS and FedEx are logistics companies that provide transportation and delivery services. They directly compete with each other in terms of their service offerings and geographic reach. This type of competition can lead to intense rivalry and the need for companies to differentiate themselves to gain a competitive advantage.
