Visst hade det varit önskvärt, men det hade också krävt att människor i grupp inte hade kunnat påverka börsen. Annars så har du ju precis samma problematik igen..
Ett straff ska stå i proportion till brottet. Om du säljer samma bil till 10 olika köpare får du allvarliga rättsliga konsekvenser. Om ett finansinstitut säljer samma aktie till 10 olika köpare är det aja baja med lite böter.
Citat:
Let’s assume that a firm fails on a $50 million position on which it is owed $50.1 million. If the Target Fed funds rate the previous day was 1%, then the fails charge will be 2% per year and it will be applied to the $50.1 million total value of the trade. This will result in a charge for the firm of $2,783.33 for that day.

den volatila aktiekursen främst orsakats av ett småspararuppror
Har du en källa på det? Jim Cramer?
Sedan januari 2020 har det varit en daglig dark pool volym på 40-60%. Nästan alltid över 50%.
Det har gjorts studier som visar att volatilitet i S&P 500 sker när börsen är stängd, då privataktörer vanligtvis inte kan handla aktier. GameStop används som exempel.
Citat:
The world’s stock markets display a decades-long pattern of overnight and intraday returns seem- ingly consistent with only one explanation: one or more large, long-lived quant firms tending to expand its portfolio early in the day (when its trading moves prices more) and contract its portfolio later in the day (when its trading moves prices less), losing money on its daily round-trip trades to create mark-to-market gains on its large existing book. In the fourteen years since this extraordinary pattern of overnight and intraday returns was first noted in the literature, no plausible alternative explanation has been advanced. The main question remaining is therefore which of the few firms capable of profitably trading in this manner are guilty of having done so. If any of this is news to you, it is because the people you trust to alert you to such problems still haven’t told you.
