Regardless of intent, or if manipulation is happening in this case, or whether or not it is currently legal, this type of activity potentially allows for someone to artificially manipulate prices to their advantage at the cost of other market participants. Hence, why shouldn't we make such activity illegal for this reason alone? Why leave a now obvious loophole in our financial system, that could be potentially be abused? We made wash sales trading illegal. Why shouldn't this pattern of activity also be made illegal - when wash sales trading is deemed illegal? If your argument is abuse will happen anyways - why even bother having any financial laws?
