Key Takeaways
Quick answer
Risk is the uncertainty — including the chance of losing money — that comes with every investment. The SEC says investors generally seek higher returns to compensate for taking more risk. That is what investors demand, not what they are promised: a riskier investment can still lose money.
- The SEC defines risk as the uncertainty and potential financial loss in any investment decision.
- Investors seek higher returns for taking more risk, but a higher return is never guaranteed.
- FINRA's historical figures rank stocks above bonds and cash for return — and stocks also fell 57% in 2008–2009.
- Holding a broad portfolio for longer reduces the chance of losing principal; it does not remove it.
- UK regulators class all crypto-assets as high risk and speculative.
What does “risk” mean in investing?
In everyday speech, “risky” just means “might go wrong”. Regulators are more precise. The US Securities and Exchange Commission’s investor site, Investor.gov, puts it this way: “All investments involve some degree of risk. In finance, risk refers to the degree of uncertainty and/or potential financial loss inherent in an investment decision.”
The Financial Industry Regulatory Authority (FINRA), which oversees US brokerage firms, uses a similar definition: “Risk is any uncertainty with respect to your investments that has the potential to negatively impact your financial welfare.”
Notice the two ideas packed into both definitions:
- Uncertainty — you do not know in advance what the investment will be worth next week or in ten years.
- Possible loss — the outcome can be worse than what you put in, not just “less good than hoped”.
“Return” is the other half of the pair: the gain or loss you actually make, from price changes plus any income such as interest or dividends.
Why does more risk usually come with higher potential return?
Investor.gov states the basic relationship: “In general, as investment risks rise, investors seek higher returns to compensate themselves for taking such risks.” FINRA says the same thing from the other side: the level of risk of an investment or asset class typically correlates with the level of return it might achieve.
Read the wording carefully. Investors seek higher returns; an investment might achieve them. Neither regulator says that taking more risk will pay off. Risk means the range of outcomes is wider — upwards and downwards. A higher potential return and a higher chance of loss are two sides of the same coin.
That is why “high return, low risk” is a phrase to treat with suspicion. If something offers both, ask what risk you are not being told about.
How have stocks, bonds and cash compared over time?
FINRA gives a simple historical ranking of long-term average annual returns:
| Asset class | FINRA historical average (per year) |
|---|---|
| Stocks | Just over 10% |
| Corporate bonds | Around 6% |
| Treasury bonds | 5.5% |
| Cash equivalents (e.g. short-term Treasury bills) | 3.5% |
FINRA does not state the period or data source behind these averages, so treat them as a rough ordering, not a forecast. Past performance does not predict future results — the SEC says so plainly in its guidance on investment performance claims.
The same ranking applies to risk. The SEC’s beginners’ guide to asset allocation says stocks have historically had the greatest risk and highest returns of the three main asset categories, and that bonds are generally less volatile than stocks but offer more modest returns. Investor.gov adds that “Large company stocks as a group, for example, have lost money on average about one out of every three years.”
FINRA’s reminder of what that can mean in practice: anyone planning to retire in the “2008 to 2009 timeframe—when stock prices dropped by 57 percent” with most savings in stocks may have had to rethink their plans.
What are the main types of investment risk?
Investor.gov and FINRA list several kinds of risk. They overlap, but naming them helps you ask better questions about any investment:
| Risk | What it means (per Investor.gov / FINRA) |
|---|---|
| Market / volatility risk | Prices move up and down because of market conditions, even for stable companies. |
| Business risk | The company behind an investment fails. Common stockholders are paid last, after bondholders and preferred stockholders. |
| Inflation risk | Rising prices reduce what your money can buy — a particular risk for fixed-interest savings. |
| Interest rate risk | When rates rise, existing bonds fall in value; selling before maturity can mean a loss. |
| Liquidity risk | You cannot find a buyer or seller when you want to trade. |
| Concentration risk | Too much money in one investment, such as a single stock. |
| Political and currency risk | Events abroad or exchange-rate moves change what a foreign investment is worth to you. |
On inflation, Investor.gov is direct: “Inflation reduces purchasing power, which is a risk for investors receiving a fixed rate of interest.” On liquidity: it is “the risk that investors won’t find a market for their securities, potentially preventing them from buying or selling when they want.”
Does holding an investment for longer make it less risky?
Partly. FINRA says: “Based on historical data, holding a broad portfolio of stocks over an extended period of time (for instance a large-cap portfolio like the S&P 500 over a 20-year period) significantly reduces your chances of losing your principal.”
Three details matter. It refers to a broad portfolio, not a single stock or coin. It says the chance of loss is reduced, not removed. And it is based on historical data, which cannot promise the future.
Large falls also take a lot of recovering. An illustrative calculation using FINRA’s 57% figure:
- $10,000 × (1 − 0.57) = $4,300 after the fall.
- To get back to $10,000 you need $10,000 ÷ $4,300 − 1 ≈ 132.6% growth.
This is why your time horizon matters. Investor.gov defines it as “the number of months, years, or decades you plan to invest to achieve your financial goal.” Money you need soon has little time to recover from a fall.
How does risk and return apply to crypto?
The same logic applies, but the range of outcomes is wider. The UK Financial Conduct Authority (FCA) says: “While not all cryptoassets are the same, they are all high risk and speculative as an investment.” It also warns: “If you decide to invest in crypto then you should be prepared to lose all your money.”
The FCA gives its own example: Bitcoin peaked at £93,947 on 6 October 2025 and was £65,350 on 1 December 2025 — a fall of 30.44% in under two months. Several of the risks above show up in crypto in sharper form: volatility, liquidity (thin markets for smaller tokens), concentration (one coin) and business risk (the platform holding your coins).

How can a beginner manage investment risk?
FINRA names asset allocation and diversification as the main tools, with hedging and insurance as costlier extras. In plain steps:
- Know your risk tolerance. Investor.gov calls it “your ability and willingness to lose some or all of your original investment in exchange for potentially greater returns.” Ability (can you afford the loss?) and willingness (can you stomach it?) are different questions.
- Match risk to time horizon. Short-term money belongs in lower-risk places.
- Spread your money. Our guide to diversification explains how, and its limits.
- Size each position. Decide in advance how much you could lose on any single holding — see position sizing.
What are the risks of chasing higher returns?
- Higher return is not owed to you. Regulators describe what investors seek, not what they get. Riskier assets can lose some or all of your money.
- Past averages mislead. FINRA’s long-term figures hide years like 2008–2009. The SEC warns that past performance cannot predict future performance.
- Concentration magnifies losses. FINRA: “The more financial eggs you have in one basket, say all your money in a single stock, the greater risk you take.”
- Fraud uses the language of return. Promises of high returns with little or no risk are a classic scam sign. Learn the red flags of crypto scams.

Frequently asked questions
Is a higher-risk investment always better over the long run?
No. Investors seek higher returns for taking more risk, but regulators do not say they will receive them. A higher-risk investment can lose money over long periods too.
What is the difference between risk tolerance and time horizon?
Time horizon is how long you plan to invest. Risk tolerance is your ability and willingness to lose some or all of your money for potentially greater returns. Investor.gov treats both as inputs when choosing an asset mix.
Is cash completely safe?
Cash is the safest of the three main asset categories in the SEC’s guide, but Investor.gov warns that inflation reduces purchasing power — a real risk for money earning a fixed rate of interest.
Where do FINRA’s historical return figures come from?
FINRA’s risk page gives the averages but does not state the period or data source. We show them only as FINRA’s rough ranking, not as an expected return.
