The weak point of this statement is presenting an interpretation as factual evidence for large-scale optimization. A test on 250 S&P 500 assets is not sufficient to validate complex portfolio strategies with thousands of positions. It does not inform us about its ability to manage currency risks and liquidity constraints specific to European or emerging markets. The proof of concept is not enough to reassure about the management of Swiss institutional portfolios, which require much greater robustness. For example, simulating a portfolio of listed real estate securities with strict liquidity requirements is a completely different investment case that this example cannot faithfully reproduce.
