[Summary]
While the S&P 500 can be used to organize investment decisions, it is a theme that can lead to hasty decisions if the assumptions are incorrect.
When beginners look at the S&P 500, it is more practical to check what to check before deciding whether to buy, rather than looking at detailed theories.
In actual investment, the starting point is to check prices, performance, fees, taxes, and financial plans separately, not just based on the S&P 500.
In this article, I will explain the S&P 500 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.
What is the difference between the S&P500 and the S&P500?
When looking at the S&P500, 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. The S&P500 is not the only material for making decisions. If you want to check it, it is more realistic to look at it in conjunction with fund management, holding period, and opposing materials.
What is the S&P500 in order for beginners to view it?
If you want to look at the S&P500 as a basic guide for beginners, 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.
If you check the following points, things will be much more organized.
| Axis to check | What is S&P500? |
|---|---|
| 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
What is the S&P 500 is not only a matter of lack of knowledge. In fact, there are situations where we interpret something conveniently because we know a little bit about it.
- What is the S&P 500? 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 not to decide on just one correct answer based on the S&P500. 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 S&P 500 as a basis for making an actual judgment, check at least these five things.
- Can you explain in one sentence the purpose of looking at the S&P500?
- 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 S&P 500 is not to act faster, but to reduce unnecessary mistakes in judgment.
Summary
The S&P500 is a material for organizing 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.
- First decide the purpose of looking at the S&P500.
- 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. The S&P 500 is not a word to rush into making decisions, but rather should be treated as a tool to pause before buying or selling.
