[Summary]
While this can be used to organize investment decisions, it is a theme that can lead to hasty decisions if the assumptions are wrong.
When beginners are trying to figure out what's going on, it's more practical to check what to check first before deciding to buy, rather than going through detailed theories.
In actual investing, the starting point is to check prices, performance, fees, taxes, and financial plans separately, rather than relying solely on what's going on.
In this article, I will organize the information about making heads and tails, 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, separate the head and tail.
When looking at what is going on, first determine 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. Even if you give me the head and tail, that alone is not enough 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.
Order for beginners to watch Head and Tail wa Kurete Yare
If you want to watch ``Heads and Tails'' as a basic game for beginners, first of all, the premise is narrow. 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 | Give me the head and tail and see |
|---|---|
| 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
It's not just a lack of knowledge that causes you to stumble. In fact, there are situations where we interpret something conveniently because we know a little bit about it.
- Give me your head and tail, and narrow down the indicators and conditions you look at first to three.
- Don't make a big purchase and leave things you don't understand.
- Think about living funds and investment funds separately.
- Check products and brands that you can understand
The important thing here is to not settle on a single correct answer just by giving us the head and tail. 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
Please check at least these 5 things before making an actual decision.
- Can you explain in one sentence the purpose of watching ``Heads and Tails''?
- 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 head and tail is not to speed up the action, but to reduce unnecessary mistakes in judgment.
Summary
This is a guide to help you organize your investment decisions. Even if you read it as a basic guide for beginners, treating it as a stand-alone buy/sell signal will make your judgment difficult.
The points to keep in mind are as follows.
- Determine the purpose of seeing the head and tail 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. "Give me your head and tail" is not a word that forces you to make a hasty decision, but it is realistic to treat it as a tool to pause before buying or selling.
