What Is an Investment Time Horizon?

An investment time horizon, or just time horizon, is the period of time one expects to hold an investment until they need the money back. Time horizons are largely dictated by investment goals and strategies. For example, saving for a down payment on a house, for maybe two years, would be considered a short-term time horizon, while saving for college would be a medium-term time horizon, and investing for retirement, a long-term time horizon.

Key Takeaways

  • Time horizons are periods where investments are held until they are needed.
  • Time horizons vary according to the investment goal, short or long.
  • Time horizons also vary according to the time by which you begin investing.
  • The longer the time horizon, the longer the power of compounding has to work.
  • Generally speaking, the longer the time horizon, the more aggressive an investor can be in their portfolio, and vice versa.

Understanding Risk And Time Horizon

Understanding Investment Time Horizons

An investment time horizon is the time period where one expects to hold an investment for a specific goal. Investments are generally broken down into two main categories: stocks (riskier) and bonds (less risky). The longer the time horizon, the more aggressive, or riskier, a portfolio an investor can build. The shorter the time horizon, the more conservative, or less risky, the portfolio the investor may want to adopt.

Short-Term Investment Horizon

The short-term horizon refers to investments that are expected to last for fewer than five years. These investments are appropriate for investors who are approaching retirement or who may need a large sum of cash in the near future. Money market funds, savings accounts, certificates of deposit, and short-term bonds are good choices for short-term investments since they can easily be liquidated for cash.

Medium-Term Investment Horizon

Medium-term investments are those which one expects to hold for three to ten years, such as by people saving for college, marriage, or a first home. Medium-term investment strategies tend to balance between high- and low-risk assets, so a mix of stocks and bonds would be a suitable way to protect your wealth without losing value to inflation.

Long-Term Investment Horizon

The long-term investment horizon is for investments that one expects to hold for ten or twenty years, or even longer. The most common long-term investments are retirement savings. Long-term investors are typically willing to take greater risks, in exchange for greater rewards.

Tip

Generally speaking, the longer your investment horizon, the more aggressive you can be in choosing your investments.

Example of an Investment Time Horizon

Let’s say two people marry, and while they live in the city now, they’d eventually like to move out to the suburbs in a few years. But they don’t have the money for a down payment on a house, so they’ll need to start saving up. That’s a short-term investment horizon, so they’ll probably want to go with something relatively conservative, like a money market fund, to avoid any sharp swings in stocks.

Meanwhile, they’ve both taken advantage of their employers' 401(k) savings funds (an employer-sponsored retirement fund, sometimes with employer matching). And since they’re both young, that’s a long-term time horizon. Given the length of time until their retirement, they can afford to be very aggressive in their asset allocation, upwards of 90% of stocks, as the long investment horizon should allow their portfolio to recover from any short-term downturns.

Next, a baby comes along! Now they have to start thinking about saving for college. That’s more of a medium- or long-term goal, so they can be pretty aggressive in the beginning and then turn a little more conservative as high school graduation for the child comes along. But there is a government saving plan (529) that allows your contributions to grow tax-free, as long as they’re used for educational expenses. 

Investment Horizon and Risk

Each type of investment carries different forms of risk, which should be factored into your investment strategy. Businesses can fail, borrowers can default, and even sound investments can be vulnerable in a market downturn. Below, we'll outline some forms of risk and their effects on each type of investment.

Inflationary Risk

Inflationary risk refers to the danger that the real value of an investment will fall, due to an unexpected increase in consumer prices. Bonds are particularly susceptible to inflation, since coupon rates are typically fixed; an unexpected spike in inflation could erode any expected gains from the investment. However, it is possible to ameliorate inflationary risk to bonds through Treasury Inflation-Protected Securities.

Interest Rate Risk

Interest rate risk is the danger that an unexpected rise in interest rates could eat away some of the gains of an investment. Like inflationary risk, this is typically a concern for fixed-income securities, like bonds. This risk can be reduced by holding bonds of different durations, or investing in interest rate derivatives.

Business Risk

Business risk refers to the danger that a company might fail or go bankrupt, causing any stocks or bonds issued by that company to plummet in value. While no company is immune to business risk, you can go a long way towards avoiding the riskiest companies by carefully evaluating their business plans. You can also reduce your exposure to any one business by having a diversified portfolio.

Default Risk

Default risk is the probability that a borrower will be unable to repay its debts. This usually refers to bond issuers, but it could also refer to other debt-based securities. You can reduce your exposure to default risk by investing in bonds with high credit ratings.

Market Risk

Market risk, or volatility risk, refers to the chance that the value of an investment could be negatively impacted by speculative behavior, market crashes, or other world events. Since markets trend upwards in the long run, market risk is typically a larger concern for short- and medium-term investment horizons.

Investment Horizon FAQs

What Is an Investment Horizon?

An investment horizon refers to the timeline in which an investor plans to gain value on their investment. This can range from a few years to several decades.

Why Is an Investment Horizon Important?

The length of an investment horizon will determine what types of investment products are most suitable for the investor's goals. Typically, investors seek stable assets for short-term investing. Riskier investments are more acceptable on a longer-term investment horizon, since markets overall tend to trend upwards.

What Is a Medium-Term Investment Horizon?

The medium-term investment horizon typically refers to investments of five to ten years, such as people saving for a child's college education.

What Does Long-Term Horizon Mean?

The long-term horizon refers to investments that have a decade or more to accumulate profits. The most common type of long-term investment is saving for retirement.

What Is the Ideal Investment Horizon?

Since interest compounds exponentially, a longer investment horizon can generate much greater profits than a short-term investment. This is why it is important to save for retirement early—a small investment now can generate high returns if it has a few decades to grow.

The Bottom Line

Every investor needs to carefully evaluate their own goals and investment timeline before deciding where to put their money. Savings accounts and CDs may be a convenient place to store money over the short term, but will quickly lose their value to inflation. Conversely, aggressive investments in the stock market will generate high expected returns in the long run, but they will remain susceptible to short-term market fluctuations. It falls on each investor to decide the optimal balance of risk and rewards.
