Time Horizon vs Patience Horizon
Your calendar can say twenty years. Your patience can run out in eighteen months. The second clock is the one that decides whether a method works for you.
Three clocks, not one
Time horizon is usually treated as a single number: when do you need the money? That is only the first clock.
- Investment horizon — when you expect to start drawing on the capital.
- Decision horizon — how often you review and are willing to act.
- Patience horizon — how long you can watch a position or a method underperform before you abandon it.
The third is psychological. It is the distance between “I believe the thesis” and “I cannot take this any more.” For some people it is years. For others it is weeks. A method that requires the first and delivers the second will be abandoned before it has a chance to work.
Why value investors quit
Value investing can underperform for years, not months. The 2017–2020 stretch is a recent example: growth led, cheap stocks lagged, and a large number of people who called themselves value investors switched. Those who held through the underperformance were later rewarded. Those who switched in 2019 were punished twice — late to growth, and missing the value recovery.
The method did not fail. The patience horizon failed. If you cannot sit through two or three years of looking wrong while other styles print money, value is not available to you, regardless of how long your retirement date is.
Passive is not exempt
Buy-and-hold indexing asks for a long patience horizon in a different costume. You own every drawdown. The ASX All Ordinaries has historically recovered over long rolling periods, but that statistic describes someone who held. It does not describe someone who sold in March 2020, waited, and bought back higher. Their return is different, and usually worse.
A long investment horizon does not mean every dollar can stay invested for twenty years. Near-term spending, a house deposit, or school fees shorten the effective horizon for that slice of money. Mixing the clocks is how people end up forced sellers.
The useful question
If you bought something today and it went sideways or down for eighteen months while a different method ran, would you hold, review, or exit? Be specific. The answer tells you more about which methods you can run than any financial plan.
What to do with this
Write your patience horizon in months for the method you are most drawn to. If it is shorter than the method’s typical underperformance cycle, either add structure (smaller size, a pre-written review rule) or choose a different method.
