[Summary]
The hole-in-the-bucket theory is a concept that shows that even if there is income or operating profit, it leaks through expenses and losses.
The benefit of the hole-in-the-bucket theory is that it doesn't guarantee profits, but that it helps organize the material you need to look at.
In actual investing, the starting point is to check fees, taxes, waste, and delayed stop-losses. However, you need to be careful that it is easy to ignore omissions by looking only at the deposit power.
In this article, we will organize the hole-in-the-bucket theory 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, divide using the hole in the bucket theory.
When looking at the hole-in-the-bucket theory, first separate what you want to judge. The information you need changes 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 hole-in-the-bucket theory is not enough alone to make a decision. If you want to check it, it is more realistic to look at it in conjunction with fund management, holding period, and opposing materials.
Don't overestimate the merits of the hole-in-the-bucket theory
If we look at the hole-in-the-bucket theory as an advantage, we first make narrow assumptions. 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 hole in the bucket theory |
|---|---|
| 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 hole in the bucket theory stumbles not only when you lack knowledge. In fact, there are situations where we interpret something conveniently because we know a little bit about it.
- Decide first what will be visible using the bucket hole theory
- Differentiate between conditions that bring about benefits and conditions that do not.
- When expectations are too high, test with a small amount
- Write down the terms of withdrawal before considering profits.
The important thing here is not to settle on a single correct answer based solely on the hole-in-the-bucket theory. 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 hole-in-the-bucket theory as a basis for making an actual decision, check at least these five things.
- Can you explain in one sentence the purpose of watching Hole in the Bucket Theory?
- 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 hole in the bucket theory is not to act faster, but to reduce unnecessary errors in judgment.
Summary
The hole in the bucket theory is a material for organizing investment decisions. Even if you read it as an advantage, treating it as a stand-alone buy/sell signal will make your judgment difficult.
The points to keep in mind are as follows.
- Decide the purpose of looking at the hole in the bucket theory 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

The more knowledge you have, the safer it seems, but in the market it can become dangerous if you use it incorrectly. The hole-in-the-bucket theory should not be used as a word to rush into judgment, but rather as a tool to help you pause before buying or selling.
