Bull Market

Sustained period of rising stock prices, typically a 20%+ rally.

A bull market is a sustained period of rising asset prices across an entire financial market or sector. While most commonly associated with stock markets, the term can also apply to bonds, real estate, commodities, or currencies. In equity markets, a bull market is traditionally defined as a rise of 20% or more in a broad market index, such as the S&P 500, from a recent low point. This upward trend is typically driven by strong economic growth, high employment, rising corporate profits, and positive investor sentiment. During a bull market, investor confidence is high, creating a self-reinforcing cycle. As stock prices rise, investors buy more assets in anticipation of future gains, which in turn pushes prices even higher. This period is also characterized by increased initial public offering (IPO) activity and high trading volumes, as companies seek to capitalize on the public's appetite for equities. For retail investors, bull markets offer significant opportunities for wealth accumulation, particularly through buy-and-hold strategies. However, a common pitfall during these periods is overconfidence. Investors may mistake a rising market for personal financial genius, leading them to take on excessive risk, buy overvalued assets, or neglect diversification. Understanding that bull markets do not last indefinitely helps investors maintain a balanced portfolio that can withstand eventual market downturns.

If the S&P 500 index hits a cyclical low of 3,000 points and subsequently climbs to 3,600 points, the total gain is calculated as (3,600 - 3,000) / 3,000 = 0.20, or 20%. Because the index has risen by exactly 20% from its trough, the market has officially entered a bull market.
