An "active market" refers to a scenario where there is a high level of demand and supply of goods and services. Several synonyms for this term include "buoyant market," "lively market," "brisk market," "spirited market," "thriving market," and "busy market." These terms are used interchangeably to describe market conditions where there is a significant exchange of products, services, and ideas between buyers and sellers. Active markets are attractive to businesses and investors because they offer opportunities for growth and profitability. Conversely, slow markets or stagnant markets are not desirable as they are characterized by low demand and limited supply, leading to financial losses and reduced investment prospects.
