Executive Summary

Financial expert Michael Markowicz criticizes a widespread investment dogma in the podcast series "Swiss Economic Daily": the claim that longer investment horizons automatically mean lower risk. Markowicz argues that this statement is not scientifically sound and leads to faulty investment advice. The central thesis states: Longer time horizons increase the variance of wealth and thus the probability of experiencing a crash – they do not reduce it. The confusion between return variance and wealth variance leads to systematic poor advice at banks and from financial influencers.

The "long-term myth" is not just an academic problem – it systematically legitimizes poor investment advice. When advisors tell a customer after a market crash "stay invested, time heals all wounds," they are not speaking to scientific facts, but to a myth that has been perpetuated for decades. In an environment where financial influencers advise without conflicts of interest and regulation is weak, this myth becomes a structural trap for private investors. Markowicz's new business model – paid courses instead of commission-dependent advice – targets this gray area directly.

Detailed Summary

Markowicz makes a precise distinction between two mathematical concepts that are constantly confused in practice: return variance and wealth variance.

With longer time horizons, the average annual return becomes actually more predictable – similar to how one can predict average traffic flow on a busy road more reliably over 50 trips than over a single trip. But: "The variance of wealth always grows the longer one invests." An investor who saves for 50 years and experiences a 50 percent crash shortly before retirement loses absolutely more wealth than someone who saves for ten years. The probability of experiencing at least one significant crash increases with each additional year – statistically almost exponentially.

The well-known counterexample: a weather forecast becomes less accurate the further into the future one looks. Markets behave in reverse – one can better estimate annual returns over 20 years than for next week. Yet estimability of return is not risk reduction. Markowicz refers to Paul Samuelson (Nobel laureate, 1990s), who refuted exactly this logical fallacy in his paper "Another Dogma: Investing for the Long Run."

The practical implication: Banks and online brokers ask during onboarding how much wealth the customer can lose per year before losing sleep – perhaps 20 percent. Once an investor has stated this figure, it is irrelevant whether they save for one or ten years. The maximum tolerable risk does not change with the time horizon. The only risk reduction is a strategy change (for example: fewer stocks, more stable investments) – not the passage of time.

Markowicz founded Goal-Based-Investments five years ago to counter this proliferation of poor advice. The model: customers pay for courses and platform, not for product sales. This eliminates commission incentives. However, it became clear that a platform alone is insufficient. Many people don't understand "state-of-the-art technology" if it is complex. So an educational component was added.

Key Statements

  • The myth "long time = low risk" is mathematically false and is refuted by Paul Samuelson (Nobel laureate); longer horizons increase wealth variance and thus the probability of experiencing a crash.
  • Return variance and wealth variance are systematically confused: Annual return becomes more predictable over 20 years, but overall wealth becomes more volatile.
  • Commission-dependent advice perpetuates the myth, because it allows advisors to simply say "stay invested" during market downturns – without genuine risk analysis.

Critical Questions

  1. Evidence/Data Quality: Markowicz cites Paul Samuelson (1990s) for "Another Dogma: Investing for the Long Run" – is this paper available, and what is the current consensus in academic financial literature on the long-term risk relationship?

  2. Evidence/Source Validity: The road traffic analogy is illustrative, but: are stock market crashes really calibrated like accident probabilities? Is there not a qualitative difference (markets are adaptive, accidents are not)?

  3. Conflicts of Interest/Incentives: Markowicz's new business model (paid courses, no product commissions) is theoretically conflict-free. But are there hidden incentives – for example, that he is growth-motivated in his platform business through a fear narrative ("Banks are lying to you")?

  4. Causality/Alternatives: Is the myth primarily caused by financial advisors or by natural investor thinking (people like simple rules like "long-term = safe")? Can courses alone change this?

  5. Implementability: If wealth variance is the real risk, how does Markowicz advise concretely? According to what formula does he reduce variance for a 40-year-old with CHF 500,000 in savings?

  6. Side Effects/Risk Shifting: If someone flees into bonds/cash out of fear of wealth variance, they risk inflation erosion. Is this trade-off covered in Markowicz's courses?
