What is Bull Market?
A sustained period of rising stock prices and optimism.
Formal Definition
A bull market is an extended advance in which prices trend higher, commonly marked by a rise of 20% or more from a prior low, supported by strong sentiment, expanding earnings, and healthy economic conditions. Bull markets can last years and are the mirror image of bear markets.
In Simple Terms
It is a long stretch when stocks keep climbing and investors feel confident. It is the good-times phase of the market, the opposite of a bear market.
Example
The bull market from 2009 to early 2020 lifted the S&P 500 roughly fourfold before the pandemic selloff.
