Objectives

\n

By the end of this lesson you understand why an investment's time horizon changes the correct way to manage the risk being taken on.

\n

Time horizon is the period of time during which an investor plans to hold an investment before needing to get the money back. It isn't a property of the asset -- it's a decision made by the investor, depending on what they need that money for and when.

\n

Time horizon doesn't change an asset's intrinsic risk -- a stock is just as volatile regardless of the horizon you view it through -- but it does change the correct way to manage that risk. With a long horizon, there's more time ahead for short-term ups and downs (the volatility you saw in the previous lesson) to even out before the money is needed. With a short horizon, on the other hand, whatever result exists at the specific moment the money is needed is the one that counts, with no room to wait for a drop to recover.

\n

This has an important practical consequence: the same investment can be reasonable for a long horizon and risky for a short one, without the asset itself having changed at all. It's not that the asset becomes "safer" over time -- it's that the horizon determines how long the investor can afford to wait before having to accept whatever result exists at that moment.

\n

Example

\n

Investing in a stock intending to use that money in thirty years gives plenty of room for short-term price swings to even out before the money is needed. Investing that same amount in that same stock to cover an expense in three months doesn't give that room -- if the price has dropped right when it's needed, the investor will have to accept that result, with no time to wait for a recovery.

Summary

\n

Time horizon is how long an investor can hold an investment before needing the money. It doesn't change the asset's risk, but it does change the correct way to manage it: a long horizon gives room for short-term volatility to even out; a short one forces you to accept the result of the moment.

Why can the same investment be reasonable with a long horizon and risky with a short one?
