Investment horizon
Period for which invested money can realistically remain invested.
In brief: Period for which invested money can realistically remain invested.
Meaning in practice
The investment horizon determines which fluctuations an investor can bear and which losses must be avoided in the short term. Money needed for a planned expense in a few years needs a different approach from capital intended for decades. A long horizon does not remove risk, but can reduce the pressure to sell during a downturn.
Context for investors and traders
For traders, this term is most useful when preparing and executing an order. Its meaning depends on the venue, liquidity, time frame and order type. A single reading is not a reliable buy or sell decision.
How to use this in practice
In practice, the term should be linked to a specific trading plan: entry, exit, position size and costs belong together. In short time frames, spread, slippage and delayed execution can quickly outweigh the theoretical benefit of an observation.
What to keep in mind
Write down which observation confirms or invalidates your assumption before trading. This keeps the term a decision-making tool rather than a retrospective justification for risk already taken.
