[Summary]
John Bogle popularized low-cost index investing.
John Bogle's story is not only a story about reading the market, but also a material for checking where you tend to get impatient.
In actual investing, learning the importance of costs and long-term diversification is the starting point. However, you need to be careful that it is easy to misunderstand that with indexes you don't have to think about anything.
In this article, we will organize John Bogle's information not as "knowledge" but as steps to check before buying or selling. Don't rush to conclusions, read according to your financial amount and time horizon.
First thing to separate by John Bogle
When looking at John Bogle, 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. John Bogle is not something to judge on that alone either. If you want to check it, it is more realistic to look at it in conjunction with fund management, holding period, and opposing materials.
John Bogle and emotional misalignment
If you look at John Bogle's investment psychology, first of all, 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.
Checking the following points will make things a lot easier.
| Axis to check | What to see with John Bogle |
|---|---|
| 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
John Bogle doesn't just stumble when he lacks knowledge. In fact, there are situations where we interpret something conveniently because we know a little bit about it.
- Record your feelings of impatience and relief when you see John Bogle
- Write down the same number of reasons why you want to buy and reasons why you don't.
- Wait a day before making decisions after unrealized losses or sudden rises.
- Reduce trading amounts on days when emotions are strong
The important thing here is not to rely solely on John Bogle as the correct answer. 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 making any real judgments about John Bogle, check at least these five things.
- Can you explain in one sentence the purpose of watching John Bogle?
- 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 John Bogle is not to make you act faster, but to reduce unnecessary errors in judgment.
Summary
John Bogle is a resource for organizing your investment decisions. Even if you read it as an investment psychology, if you treat it as a standalone buy or sell signal, your judgment will be inaccurate.
The points to keep in mind are as follows.
- Decide the purpose of seeing John Bogle first.
- 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 John Bogle as a tool to pause before buying or selling, rather than as a word to rush into judgment.
