[Summary]
Winner-take-all is a structure in which profits and users are concentrated in strong companies.
What is most likely to fail in a winner-take-all approach is not the lack of knowledge itself, but the fact that you end up justifying your hasty decisions afterwards.
In actual investment, we first start by looking at the relationship between market share and profit rate. However, we cannot overlook the fact that it is easy to underestimate the room for reversal for second and lower players.
In this article, we will organize winner-take-all as a step to check before buying or selling, rather than as "knowledge". Don't rush to conclusions, read according to your financial amount and time horizon.
First, divide by winner-take-all.
When looking at winner-take-all, 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. Winner-take-all 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.
Situations where winner-takes-all is likely to fail
If you look at winner-take-all as a failure pattern, 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.
Checking the following points will make things a lot easier.
| Axis to check | A winner-takes-all view |
|---|---|
| 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 problem with winner-take-all is not only 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 winner-take-all.
- Do not mix the time frame that suits winner-take-all 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 just one correct answer based on winner-take-all. 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 a winner-take-all decision, check at least these five things.
- Can you explain in one sentence the purpose of watching winner-take-all?
- 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 confirming winner-take-all is not to move faster, but to reduce unnecessary errors in judgment.
Summary
Winner-take-all is a tool 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 the purpose of seeing winner-take-all 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 winner-take-all as a tool to pause before buying or selling, rather than as a word that forces you to make a hasty decision.
