Scalable Capital – ethischer Robo-Advisor made in Germany

Scalable Capital Office in MuenchenRobo-Advisors sind meistens nicht transparent und basieren sich auf in der Praxis nicht funktionierende Modelle wie Markowitz oder Black-Litterman. Darüber haben wir schon sowohl in kurzem Pamphlet "Anti-Asimov’s Three Laws of Robo-Advisory" als auch in fachlichem Artikel "Stripping down the robo-advisors: sparrow-brains inside" berichtet. Anders ist Scalable legt sein Modell offen und habt u.a. ein ausführliches Whitepaper veröffentlicht. Nach der Besprechung dieses Whitepapers mit Prof. Dr. Stefan Mittnik kann man eindeutig sagen: Scalable schafft den Mehrwert für Investoren. Ob dabei das Leistung/Gebühren Verhältnis passt, muss jeder für sich selbst entscheiden.

That's why I made a simple scenario simulator on my own. It is based on sample with replacement.

Stripping down the robo-advisors: sparrow-brains inside

Robo Advisor - Sparrow Brains


  • Robo-advisors promise the risk profiling in a few easy steps, which is unrealistic both from mathematical and behavioral points of view.
  • The "optimal" portfolios are usually based on Markowitz-like models, which are inapplicable in practice due to their extreme numerical sensitivity to the market parameters estimation errors.
  • Robo-advisors lure investors with low management fees but minimizing fees and maximizing the wealth is not the same. Moreover, the compound costs are not so small in the long term.
  • A positive side: Robo-advisers do not (yet) foist toxic financial products upon you.
