Why parents should understand the basics of investing

You don't need to be a financial adviser to give your children a solid financial foundation. But a few basic investment concepts will help you not only manage household finances better, but also speak to your children about money with confidence and substance.

In this article we'll look at three fundamental investment instruments β€” stocks, bonds, and ETFs β€” and explain how they differ, where each is suitable, and how to talk about them with children.

Stocks: You own a piece of the company

When a company needs capital to grow, it can raise it by selling stocks β€” small ownership stakes in the business. Every person who buys a share becomes a shareholder and gains:

  • The right to a dividend β€” a share of the company's profit (not all companies pay dividends),
  • Capital appreciation β€” if the company grows, so does the share price,
  • Voting rights β€” at the annual general meeting (relevant for significant holdings).

Stocks are historically the highest-returning investment instrument over a long time horizon. The US stock index S&P 500 has grown by an average of approximately 10% per year over the past 50 years. But beware β€” short-term swings can be dramatic. Someone who invested at the peak before the 2008 crisis had to wait nearly 5 years to return to profit.

Suitable for: Long-term investors with a 10+ year horizon who can tolerate volatility.

Bonds: You are the lender

Bonds are securities through which a company or government "borrows" money from investors. Unlike stocks, as a bondholder you have fixed, agreed terms:

  • Face value β€” the amount returned to you at maturity,
  • Coupon β€” regular interest payments (annual or semi-annual),
  • Maturity date β€” when you receive back the principal.

Government bonds (e.g. Slovak or German) are considered very safe β€” governments go bankrupt only very rarely. The return is lower, however β€” typically 2–5% per year for safe countries. Corporate bonds offer higher yields but also higher risk.

Suitable for: Investors who prioritise security over return; for portfolios with a shorter time horizon or for the portion of a portfolio that "holds" when stocks fall.

ETF funds: Diversification at low cost

An ETF (Exchange-Traded Fund) is a fund that tracks the performance of a particular index (e.g. S&P 500, MSCI World) or sector, and whose shares trade on a stock exchange. It is a hybrid between a mutual fund and a stock.

Why ETFs are revolutionary

Before their emergence (in the 1990s), retail investors had to buy shares in individual companies or pay high fees to actively managed mutual funds. ETFs changed the rules of the game:

  • Low fees β€” annual management fee (TER) typically 0.07–0.25%, whereas active funds charge 1–2%,
  • Instant diversification β€” one ETF tracking MSCI World holds shares in thousands of companies across 23 countries,
  • Transparency β€” you know exactly what you own,
  • Liquidity β€” you can sell at any time during trading hours.

Popular ETFs for long-term investing

For parents who want to invest for their children, these types of ETF are popular:

  • MSCI World ETF β€” tracks stocks from developed countries (US, Europe, Japan...); historical annual return ~10%,
  • S&P 500 ETF β€” the 500 largest US companies,
  • MSCI All Country World ETF (ACWI) β€” developed and emerging markets.

What's the difference between active and passive investing?

Active investing: The fund manager tries to beat the market β€” actively picking stocks, predicting movements and changing the portfolio. The result? Studies repeatedly show that the majority of active funds underperform their benchmark index over the long term, especially after fees are taken into account.

Passive investing: An ETF simply tracks an index. It doesn't try to be smarter than the market. The result? Long-term performance better than most active funds at significantly lower cost.

The most important lesson for every beginning investor: time in the market is more valuable than timing the market.

Risk and diversification: Don't bet on one card

Every investment carries risk. Stocks can fall. Companies can go bankrupt. Even governments can stop repaying debt. How do you protect yourself?

Diversification β€” spreading investments across different asset classes (stocks, bonds), sectors (technology, healthcare, energy), and geographies (US, Europe, Asia). If one sector falls, others may remain stable or grow.

A simple strategy for a long-term investor with a 20+ year horizon: 80–90% in global equity ETFs, 10–20% in bond ETFs. As you age, gradually shift the balance toward bonds.

How to talk about this with children β€” practical tips

For children 5–7 years: A stock = you own a small piece of an ice cream shop. If business is good, you get a little free ice cream (dividend).

For children 8–10 years: Show a real chart of the S&P 500's growth over the past 30 years. Ask: "When do you think the best time to buy was?" Answer: any time β€” those who stayed in the market earned a return.

For teenagers: Open a brokerage account together and buy a symbolic amount of an ETF. Let them track its progress. Real experience is irreplaceable.

Conclusion: Start with an ETF when you don't know where to begin

If you don't know where to start β€” an MSCI World ETF is the answer most financial experts give to people without specialist knowledge. Low fees, global diversification, historically proven performance. Invest regularly, ignore short-term swings, and let compound interest do its work.

And remember: every euro invested today for your child could be five times that amount in 20 years. The best time to start is as soon as possible.
