In reaction to the FT article ‘ a theory of (almost) everthing on financial markets‘, I add that Academic research have shown no clear evidence of such a negative effect of ETFs on the market. On the contrary, the 3 main conclusions from the ETF Research academy are:

𝟏. ETFs help generate a more competitive asset management environment but they will not replace the best-performing active funds. But, in turn, those active managers must be able to show they can deliver true alpha.
𝟐. ETFs don’t automatically cause higher volatility and do not automatically increase the correlation between stock prices.
𝟑. An equilibrium will be reached in the market with a distinct place for both active and passive management style. It is based on the idea that due to poor active manager performances, passive flows increase. Then, the more flows in passive fund increase, the more opportunities for active funds will arise and that will at some point allow active funds to better perform.

👉 Relying on trustful sources to set one’s conviction is key to build efficient portfolio.
