[Summary]
The Magnificent 7 effect is a phenomenon in which large US tech companies push up the overall index.
What is most likely to fail with the Magnificent 7 effect is not the lack of knowledge itself, but rather the situation in which a hasty decision is justified later.
In actual investment, we first start by looking at the contents of index investments and concentration risks. However, we cannot overlook the fact that even though it is distributed, bias tends to occur.
In this article, we will organize the Magnificent 7 effect not as "knowledge" but as a procedure to check before buying or selling. Don't rush to conclusions, read according to your financial amount and time horizon.
First things to differentiate based on the Magnificent 7 effect
When looking at the Magnificent 7 effect, 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. The Magnificent 7 effect 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 the Magnificent 7 effect is likely to fail
If we look at the Magnificent 7 effect as a failure pattern, we must 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 | What to see with the Magnificent 7 effect |
|---|---|
| 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 Magnificent 7 effect 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.
- Don't decide to buy or sell the moment you see the Magnificent 7 effect.
- Do not mix the time axis that matches the Magnificent 7 effect 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 rely solely on the Magnificent 7 effect 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 using the Magnificent 7 effect as a basis for actual judgment, check at least these five things.
- Can you explain in one sentence the purpose of viewing the Magnificent 7 effect?
- 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 the Magnificent 7 effect is not to speed up action, but to reduce unnecessary judgment errors.
Summary
The Magnificent 7 Effect is a material 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 first the purpose of seeing the Magnificent 7 effect.
- 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 the Magnificent 7 effect as a tool to pause before buying or selling, rather than as a word to rush into judgment.
