[Summary]
A double bottom is a type of bottom that tests the bottom twice and rebounds.
When you replace double bottom with actual examples, it becomes easier to see the difference between situations where it can be used and situations where it is difficult to use.
In actual investment, we start by confirming a reversal after breaking through the neckline. However, it cannot be overlooked that if you buy before the bottom price is confirmed, you will be caught up in a breakout.
In this article, we will organize the double bottom 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, divide by double bottom
When looking at double bottom, first decide 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. Double bottom is not the only factor in making 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.
Thinking about double bottom as an example
If we look at double bottom as an example, we first need to 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 a double bottom |
|---|---|
| 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
Double bottoming doesn't just happen when you don't have enough knowledge. In fact, there are situations where we interpret something conveniently because we know a little bit about it.
- Focus on one scene where double bottom works well
- Even if the price movements are similar, if the background is different, they are treated as different things.
- View not only successes but also failures using the same criteria.
- Check if you can reproduce it with your own amount of funds
The important thing here is not to settle on just one correct answer based on double bottom. 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 an actual decision on double bottom, check at least these five things.
- Can you explain in one sentence the purpose of watching Double Bottom?
- 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 for double bottoms is not to act faster, but to reduce unnecessary errors in judgment.
Summary
The double bottom is a material for organizing investment decisions. Even if you read it as an example, your judgment will be inaccurate if you treat it as a standalone buy/sell signal.
The points to keep in mind are as follows.
- Decide first the purpose of seeing Double Bottom
- 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 double bottom as a tool to pause before buying or selling, rather than as a word that forces you to make a hasty decision.
