How a beginner can build an investment portfolio: a simple scheme
A first portfolio is two or three broad funds and one rule: how much in stocks, how much in bonds. The rest is detail.
- A first portfolio is two or three broad funds, not ten separate companies.
- The stock share depends on the horizon: the further the goal, the more stocks.
- Add on a schedule and once a year bring the shares back to plan.
What a portfolio is
A portfolio is everything you have put money into, taken together: stocks, bonds, funds, savings. Its point is that the parts behave differently: when one falls, another holds the result.
Step 1. Horizon and nerves
Two questions decide almost everything:
- When will you need the money? In three years — bonds form the core. In twenty — stocks.
- What will you do if the portfolio drops by a third? If you would sell in panic, hold fewer stocks than the horizon suggests.
Step 2. Shares of stocks and bonds
| Time to goal | Stocks | Bonds | What to expect |
|---|---|---|---|
| Up to 3 years | 0–20% | 80–100% | Small swings, small growth |
| 3–10 years | 40–60% | 40–60% | Declines of up to 20–25% |
| Over 10 years | 70–90% | 10–30% | Declines of up to 40–50%, higher growth |
These are reference points, not a rule. Why bonds are needed and how they work is in the bonds guide.
Step 3. What to fill it with
A beginner does not need to pick individual companies. Funds are enough:
- US stocks — an S&P 500 fund. What it is — in the guide “The S&P 500”.
- Stocks of the rest of the world — a fund of developed and emerging countries, so as not to depend on one country.
- Bonds — one broad bond fund.
Three examples
| Calm | Middle | For growth | |
|---|---|---|---|
| US stocks | 20% | 40% | 55% |
| World stocks | 10% | 20% | 30% |
| Bonds | 70% | 40% | 15% |
The examples show the principle, not a ready answer: your country, taxes and available funds may change the set.
Step 4. Add and rebalance
- Add money on a schedule — once a month or a quarter, without looking at the news.
- Check the shares once a year. Stocks grew to 75% instead of 60% — direct the next contribution to bonds.
- Change the shares only along with the goal, not along with the market's mood.
Common mistakes
- Ten funds holding the same companies: it looks like variety, but inside it is the same thing.
- Half the portfolio in one favourite company.
- Buying whatever grew most last year.
- Selling in a decline “to wait it out”.
- Money needed in a year sitting in stocks.
Work out the shares for your horizon and age.
