[Summary]
Merely remembering the meaning of diversified investment is not enough to make actual buying and selling decisions. You need to look at the context in which the words are used.
When looking at diversified investing for beginners, it is more practical to check what to check before deciding on a purchase, rather than going through detailed theories.
In actual investment, the starting point is to check prices, performance, fees, taxes, and financial plans separately, not just based on diversified investment.
In this article, we will organize diversified investing 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 thing to do when diversifying your investments
When looking at diversified investments, first determine what you want to make a decision on. 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. Diversified investment is not the only factor in 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.
Order in which beginners should look at diversified investing
If you look at diversified investing as a basic 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.
Checking the following points will make things a lot easier.
| Axis to check | What to look for in diversified investment |
|---|---|
| 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 diversified investing 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.
- Narrow down the indicators and conditions you look at first into three when making diversified investments.
- 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 settle on one correct answer just by diversifying your investments. 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 diversified investment as a basis for making an actual decision, check at least these five things.
- Can you explain in one sentence the purpose of looking at diversified investments?
- 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 diversification is not to act faster, but to reduce unnecessary mistakes in judgment.
Summary
Diversification 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.
- Decide first the purpose of looking at diversified investment
- 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 diversified investment as a tool that allows you to pause before buying or selling, rather than a word that forces you to make a hasty decision.
