Tu perds de l’argent en investissant avec ta banque (c’est mathématique ..)

In this French‑language explainer, the presenter argues that investing through banks, insurance companies, or any financial intermediary that offers actively managed funds inevitably leads to lower net returns because of higher fees and systematic under‑performance compared to passive index‑tracking ETFs. He introduces the SPIVA study from Standard & Poor’s, which shows that roughly 80‑85 % of active funds under‑perform their benchmarks over multi‑year periods. Using a concrete Swiss active fund (with a TER of 1.2 % and a 5‑year net return of 5.6 %) versus the iShares Core SPI ETF (TER 0.1 %, 5‑year net return 7.1‑7.2 %), he demonstrates the fee and performance gap. A compound‑interest calculator example over a 20‑year horizon (CHF 1 000 initial + CHF 200 monthly) shows the active fund ending at about CHF 79 000 while the passive ETF reaches roughly CHF 109 000, a loss of about CHF 29 000 due to higher costs and lower returns. The video concludes by urging viewers to become autonomous investors, build their own passive “socle” (core portfolio) with ETFs, and offers a free training link for learning how to do so.
