What does investing mean?
Investing is committing resources—often money—to an asset or activity with the expectation of future benefits. Those benefits are uncertain. The value of an investment can rise or fall, and an investor may receive less than the amount originally committed.
Investing is different from saving. Savings generally prioritize access and preservation of money, while investing accepts some uncertainty in pursuit of a possible future return. Neither label guarantees a particular outcome.
Understanding risk and return
Return describes the gain or loss associated with an asset over a period. Risk refers to uncertainty about outcomes, including the possibility of loss. Different assets have different sources of risk, and higher potential returns do not reliably materialize.
Past performance describes what happened during a particular period; it does not establish what will happen next. Economic conditions, company performance, interest rates and unexpected events can all affect outcomes.
Why diversification matters
Diversification means spreading exposure across multiple assets, issuers, sectors or sources of risk rather than relying on a single holding. Different assets may respond differently to the same event.
Diversification can reduce concentration risk, but it cannot eliminate all investment risk. Many assets can decline together during periods of market stress, and a diversified portfolio can still lose value.
Time horizon and liquidity
A time horizon is the period over which money may be invested before it is needed. Liquidity describes how easily an asset can be converted into cash without a substantial change in its price. Some assets are easier to sell quickly than others.
The concept of compounding
Compounding occurs when returns remain invested and can themselves generate future returns. Its effect depends on the rate of return, length of time, costs, taxes and whether returns are positive or negative. Compounding is a mathematical process, not a guarantee of growth.
Costs and fees
Costs can affect the amount retained from an investment. Depending on the asset and account, costs may include transaction fees, management expenses, spreads, taxes or other charges. Comparing costs requires understanding what is included and how it is calculated.
