Bull and bear markets describe broad price trends. They are useful labels for discussing risk, but they are not instructions to buy or sell. This guide explains the terms and shows how to review a long-term plan when prices move sharply.
What is a bull market?
A bull market is a period of broadly rising prices. The SEC investor glossary explains the term. Commentators sometimes use a 20% rise from a low as a practical marker, but definitions and starting dates differ. A rally can occur while the wider economy remains weak, and gains may be concentrated in a few companies.
What is a bear market?
A bear market describes a broad decline. A fall of roughly 20% from a recent peak is a common convention, as described in the SEC glossary entry on bear markets. A smaller correction can still cause substantial losses. A market decline does not by itself establish that an economy is in recession.
Why recovering from a loss takes a larger gain
Consider a hypothetical investment worth $1,000. After a 20% fall, it is worth $800. Returning to $1,000 requires a $200 gain, which is 25% of $800. Following a 50% fall to $500, the required recovery is 100%. These are arithmetic examples, not forecasts; they exclude fees, taxes, deposits and withdrawals.
This asymmetry helps explain why the amount of risk you can afford matters more than choosing a dramatic market label.
What market indicators can and cannot tell you
Investors examine earnings, interest rates, valuations, trading volume and market breadth. Each provides context, but none reliably announces the exact start or end of a cycle. Moving averages react to price changes and can reverse repeatedly. Historical sector patterns are not guarantees that a particular stock or bond will hold its value next time.
Bonds also carry risk. A rise in interest rates can reduce bond prices, and weaker issuers can default. Stocks and bonds can fall together, so diversification should not be presented as complete protection.
A checklist before changing your investments
- Identify the goal. Money needed for bills or a near-term move should not depend on a stock-market recovery.
- Review available cash. Keep an accessible reserve appropriate to your obligations and income stability.
- Check concentration. Several funds can hold many of the same companies.
- Compare the current mix with your plan. A price change may alter risk even if you have made no trades.
- Account for costs. Selling can trigger taxes or fees; changing course repeatedly creates additional friction.
- Seek qualified help when needed. Cross-border accounts, retirement withdrawals and tax residency require more than a market headline.
A rebalancing example
Suppose an illustrative $10,000 portfolio was intended to hold $6,000 of equities and $4,000 of bonds. After price changes, equities represent $7,000 out of an $11,000 total. The equity share is about 63.6%, rather than 60%. The relevant decision is whether that drift exceeds a rule chosen in advance, not whether a headline calls the market bullish. New contributions may help adjust the mix without selling, although availability and tax treatment matter.
