What Is a Bull Market?

Steven Levine, Founder of TickerPosts and OpenClassActions.com1 min readLast reviewed

A bull market is a broad, sustained rise in stock prices. It usually describes an index or asset class, not just one stock having a good week.

What can drive a bull market

Bull markets can be supported by several forces:

  • Improving earnings expectations.
  • Falling or stable interest rates.
  • Economic growth.
  • Strong investor confidence.
  • New technology or productivity expectations.
  • Liquidity moving into stocks.

The common thread is that investors become more willing to pay for future earnings.

Bull market does not mean every stock is safe

In a strong market, weak companies can rise alongside strong ones. Popular themes can also become crowded. A stock may go up because the whole market is rising, not because the company's fundamentals improved.

That is why bull markets require the same basic research habits as any other market:

  • Read the company's filings.
  • Check valuation against growth and cash flow.
  • Watch debt and dilution.
  • Understand what would change your thesis.

How to stay grounded

Bull markets can make risk feel smaller than it is. Instead of assuming recent gains will continue, ask whether your portfolio still matches your goals and risk tolerance.

Rising prices are information, but they are not proof. A calm investor separates market mood from business value.
