[Summary]
The Lindy effect is the idea that the longer something lasts, the more likely it will continue in the future.
What is most likely to lead to failure due to the Lindy effect is not the lack of knowledge itself, but rather the situation in which a hasty decision is justified later.
In actual investment, the starting point is to look at long-lived companies and the durability of the system. However, it is important to note that if it is old, it is safe and easy to simplify.
In this article, we will organize the Lindy effect not as "knowledge" but as a step to check before buying or selling. Don't rush to conclusions, read according to your financial amount and time horizon.
First, let's differentiate based on the Lindy effect.
When looking at the Lindy effect, first determine what you want to judge. The information you need will change depending on whether you want to know the meaning, confirm before buying or selling, or review your current holdings.
Especially for beginners in investing, the easier the words are, the more they tend to take them as a conclusion. The Lindy effect is not the only factor in making decisions. If you want to check it, it is more realistic to look at it in conjunction with fund management, holding period, and opposing materials.
Situations where the Lindy effect is likely to fail
If we look at the Lindy effect as a failure pattern, we must first make a narrow premise. It is important not to mix up whether you are talking about the market as a whole, individual stocks, NISA or long-term funds.
If you check the following points, things will be much more organized.
| Axis to check | What to see with the Lindy effect |
|---|---|
| purpose | What do you use to judge? |
| Time axis | Which is closer to short-term trading, long-term holding, or NISA? |
| basis | Which one is more important: price, business performance, interest rates, exchange rates, or psychology? |
| risk | When things go the other way, where should you look again? |
| action | Will it lead to buying, selling, or doing nothing? |
Points that can easily cause trouble in making decisions
The Lindy effect doesn't only stumble when you lack knowledge. In fact, there are situations where we interpret something conveniently because we know a little bit about it.
- Don't decide to buy or sell the moment you see the Lindy effect.
- Do not mix the time frame that suits the Lindy effect with your own holding period.
- Don't increase your position to recoup your losses
- Don't make a decision just based on SNS or rankings.
The important thing here is not to settle on a single correct answer based solely on the Lindy effect. In investment, the meaning of the same material changes depending on the market, holding period, and amount of funds. When in doubt, prioritize confirmation over conclusion.
Checklist before buying and selling
Before using the Lindy effect as a basis for actual judgment, check at least these five things.
- Can you explain in one sentence the purpose of looking at the Lindy effect?
- Have you confirmed one or more countermeasures or failure conditions?
- Are you investing your living funds or money that will be used soon?
- Have you decided in advance the criteria for cutting losses, taking profits, and continuing to hold stocks?
- Are you making judgments based only on social media or short headlines?
Checklists are simple, but they prevent you from adding reasons after making a decision. The purpose of checking the Lindy effect is not to act faster, but to reduce unnecessary judgment errors.
Summary
The Lindy effect is a material for organizing investment decisions. Even if you read it as a failure pattern, treating it as a standalone buy/sell signal will lead to poor judgment.
The points to keep in mind are as follows.
- Decide first the purpose of seeing the Lindy effect
- Do not mix time axis and amount of funds
- Check not only good materials but also negative materials
- When using NISA and long-term funds, consider how to handle losses
- When in doubt, reduce your position or postpone it.
The more knowledge you have, the safer it seems, but in the market it can become dangerous if you use it incorrectly. It is realistic to treat the Lindy effect as a tool to pause before buying or selling, rather than as a word to rush into judgment.
