Learn together

Talk to a teenager about shares: an activity to do together

You do not need to choose a real stock to understand part ownership. An invented bakery lets you explore what a share gives ownership in, why a price can change and which questions remain unanswered. Here is a conversation plan for an adult and a teenager. Amounts use Swedish kronor, labelled SEK.

What you will learn

  • Explain the difference between buying a product and owning part of a company.
  • Calculate an ownership percentage and a changed value with the same number of shares.
  • Ask about uncertainty without turning the conversation into a search for stock tips.

Begin with a question, not a purchase

Set aside about 20 minutes, have paper and a pen ready and let the teenager begin: What do you think someone owns when they buy a share? Write the answer before the explanation. The aim is to see how the reasoning changes, not to test each other or determine who already knows the most.

Agree on a shared framework: all amounts are invented and no real money is used. You do not need an app account. If the conversation began with a social-media tip, separate the question of how shares work from whether that particular tip is correct. A familiar brand is insufficient evidence for a financial decision.

Five minutes: customer or part owner?

The fictional bakery has 1,000 identical shares. You buy five. Your ownership fraction is 5 ÷ 1,000 = 0.005, or 0.5 percent. In this model, the shares have equal rights and no new shares are issued. Ask how this differs from buying five loaves over the counter.

Buying bread gives you a product. Buying shares gives a small ownership interest in the company; it is not a bread order or a promise of a particular profit. Then swap roles: ask the teenager to explain part ownership to the adult in their own words, using a different number of shares.

Five minutes: the same ownership, a different value

At SEK 100 per share, the five shares have a combined value of SEK 500. If the price in our example changes to SEK 80, their value becomes SEK 400. That is a fall of SEK 100, or 20 percent of the starting value. The number of shares and ownership percentage remain five and 0.5 percent respectively in the model.

Ask each other to identify what changed and what stayed the same. The price is the value assigned to one share at a particular time. Here the ownership percentage uses your number of shares and the company's total number. Confusing them can make a price fall sound as though shares disappeared, even though it is their value that changed.

If the table does not fit, scroll it sideways.

Five minutes: practise not having an answer

Write three things you would need to investigate about the bakery: what it sells, what costs it has and which events could change demand. The calculation exercise contains no answers to these questions. Part of the activity is recognising the difference between an exact calculation and incomplete knowledge about a company.

Try this question: The bakery sells more bread; do we know its stock price a year from now? No, that information is insufficient to determine a future stock price. Ask the teenager to write a follow-up question. The adult can also write something they do not know; investigating together need not begin with ready-made answers.

Finish and choose the next learning step

Read the first answer again. Add a sentence about ownership and another about risk. If the calculation was difficult, continue with the What is a share? lesson. If the difference between a statement and a promise raised questions, do the claims-evaluation activity together. Choose the next step by the question that arose, not by a price that happened to rise.

Try it yourself

In the model, the teenager receives ten of the bakery's 1,000 shares. The price goes from SEK 50 to SEK 40. Calculate the ownership percentage, starting value and ending value. Which of the three measures changed?

Show the solution and explanation

Ownership is 1 percent. The starting value is SEK 500 and the ending value SEK 400. Value changed; the ownership percentage did not.

10 ÷ 1,000 × 100 = 1 percent. Ten shares multiplied by their price gives SEK 500 and SEK 400 respectively. We assumed that the company's total number of shares is unchanged.

Check your understanding

Does buying a share give the same thing as buying bread?

No. In this example, buying bread gives a product, whereas buying a share gives part ownership in the company.

Why does the example have no real companies or prices?

You can focus on the reasoning without the calculation being mistaken for a suggestion about what to buy.
