Time Horizon

What Is a Time Horizon?

A time horizon is the amount of time between making an investment and the point when you expect to need the money. It might be a few months, several years, or several decades. Because it sets the window in which an investment must work, the time horizon is one of the most important factors in deciding how to invest. Investors with a short horizon usually need stability, while those with a long horizon can generally accept more ups and downs in exchange for greater potential growth.

Why It Matters

Markets move in unpredictable ways over short periods. Stock prices can fall sharply within a single year, and bond prices can also drop when interest rates rise. Over longer periods, however, investors have historically had more time to recover from downturns. This is why a time horizon is often used to judge how much investment risk is appropriate. Money needed for a down payment next year may be better kept in cash-like holdings, while money set aside for retirement in thirty years has more room to absorb market swings.

Short, Medium, and Long Horizons

Although there is no fixed definition, the terms are often used loosely:

• Short-term: under about three years
• Medium-term: roughly three to ten years
• Long-term: more than ten years

These ranges are general conventions rather than rules. Individual circumstances, such as job stability and existing savings, also affect how long an investor can safely wait.

Time Horizon and Risk Tolerance

A time horizon is closely linked to risk tolerance, which describes how much loss an investor can emotionally and financially handle. A long horizon may allow a higher allocation to stocks, but it does not guarantee that losses will not occur or that the investor will stay calm during a decline. Many financial professionals consider both factors together when describing an investor's asset allocation.
