Bear market
A bear market is a general decline in the stock market over a period of time.[6] It is a transition from high investor optimism to widespread investor fear and pessimism. According to The Vanguard Group, "While there’s no agreed-upon definition of a bear market, one generally accepted measure is a price decline of 20% or more over at least a two-month period." |
