What is Bull Market?
A bull market is a financial market condition characterized by a sustained period of rising asset prices, typically accompanied by robust economic growth and strong investor optimism. While the term can refer to any traded asset class (such as real estate, bonds, or commodities), it is most frequently used to describe the stock market. In the context of equities, a bull market is formally defined by a rise of 20% or more in major broad-market indexes (such as the S&P 500 or the Dow Jones Industrial Average) from a recent trough, following a previous decline of 20% or more.
The driving forces behind a bull market are typically rooted in positive macroeconomic fundamentals. These include expanding gross domestic product (GDP), low or declining unemployment rates, rising corporate profit margins, and accommodative monetary policy (such as low interest rates set by the Federal Reserve). These positive conditions foster a feedback loop of investor confidence; as stock prices rise, investors become more willing to buy, increasing demand and driving prices higher. This period is also characterized by a high volume of Initial Public Offerings (IPOs) and increased merger and acquisition activity, as businesses seek to capitalize on high valuations.
While bull markets can last for several years, they do not continue indefinitely. They are inevitably punctuated by short-term market corrections (declines of 10% to 20%) and eventually end when economic growth slows or investor sentiment shifts, giving way to a bear market. For long-term investors, the key challenge during a bull market is to avoid emotional decision-making, such as taking on excessive risk or abandoning a diversified asset allocation in pursuit of short-term gains at market peaks.

PRACTICAL EXAMPLE
Following a major recession, the S&P 500 index rises from a low of 3,000 to 3,600, crossing the 20% bull market threshold. Prices continue to rise over the next three years as corporate earnings expand.
