When NOT to invest

Investing is powerful, but sometimes it's the wrong tool. Money you need within a couple of years shouldn't ride a market that can drop 20% in a season. And if you carry credit-card debt at 18%, every euro you invest instead of repaying is betting you'll beat 18% guaranteed. Almost nothing beats 18% guaranteed.

What you get asked

  1. You owe €3,000 on a credit card at 18% interest. Why is paying it off 'the best investment you'll ever make'?

    High-interest debt is a guaranteed negative return; killing it is a guaranteed positive one. Stocks average roughly 7-10% a year over long periods, nowhere near a certain 18%.

  2. Money you'll need within about ___ years generally doesn't belong in the stock market.

    Markets regularly drop 20-30% and can take years to recover. A short horizon means you might be forced to sell right at the bottom.

  3. Put the classic 'order of operations' for a spare €100/month in sequence

    Minimums protect you from penalties, the cushion stops new debt, then the guaranteed 'return' of clearing expensive debt beats the market's maybe.

  4. Marco wants to buy a flat in 18 months and has the deposit saved. A friend says 'put it in stocks meanwhile'. What's the flaw?

    In early 2020 the S&P 500 fell about 34% in five weeks. Marco's timeline can't wait out a storm like that. Short-horizon money stays boring on purpose.

  5. Which debt is usually fine to keep while you invest?

    The rough test: debt costing more than ~6-8% gets killed first; cheap long-term debt like many mortgages can coexist with investing. Expensive debt first, always. 🐜
