Regulating manipulation in the era of meme stocks, crypto-assets and inelastic markets

Research output: Working paperScientificpeer-review


The GameStop and AMC sagas clearly show that the US approach of market manipulation has long underexposed the objective side of traders’ behavior and relied too much on subjective aspects. When I wrote this back in 2008, I also proposed an objectified definition of market manipulation based on the unsupported price pressure standard. In this contribution I have tested my proposal from 2008 against the facts of the GameStop case, and it appears that the unsupported price pressure standard is indeed a useful tool also in this context. Following Popper's line of thought, this finding is not necessarily very significant, as it merely confirms a proposition. However, since it is highly unlikely that the US anti-manipulation provisions can be used in the GameStop and AMC case, we now have further reason to conclude that those provisions are flawed.
