Bull Market
A bull market is a sustained period of rising share prices, typically 20% or more from a recent low.
Bull markets are driven by growing earnings, falling interest rates, improving economic conditions, or expanding investor optimism — often several at once. The longest US bull market ran from 2009 to 2020, a period of more than a decade.
The term comes from the way a bull attacks — thrusting upward. A bear market (falling 20% or more from a recent high) reflects the opposite: a bear swipes downward.
Bull markets typically last longer than bear markets on average, but individual sector bull markets can diverge sharply from the broader index.
