How to set an investment horizon: write down how long and why
Every can has a best-before date. Every investment should have your own: the Horizon, the H in HOLD.
A horizon is not a market forecast. It is how long you plan to hold and why. Without one, news or a limited-time offer can steer you.
How to write one
- Write a specific time, such as "five years", not "long term".
- Write the reason, such as "down payment" or "retirement".
- Write a review date, and check then whether the reason still holds.
- If you need the money within a few years, be careful about price swings. The shorter the horizon, the more flexibility to keep.
Different things, different horizons (illustration)
- Index fund: usually measured in years.
- A home you live in: the years you plan to live there.
- A craze toy or collectible: the hype may fade in days or months.
A look at history: how long a fall took to recover
In the S&P 500 scenarios used in the junjun.life stress test, the 2007–09 financial crisis fell about 57% from peak to bottom over about 1.4 years, then took about 4 more years to return to the earlier high (price index, dividends excluded). A very short horizon may not leave time to wait.
This is a historical scenario and not a guarantee about the future.
FAQ
Must a horizon be long?
No. It should match what the money is for, and you should write down the reason.
Can I change it later?
Yes, but do it on review day by checking your original reason, and record why you changed it.
