"As a brokerage firm, we have many financial requirements, including SEC net capital obligations and clearinghouse deposits. Some of these requirements fluctuate based on volatility in the markets and can be substantial in the current environment." Can anyone translate that? It seems to be referring to: * https://en.wikipedia.org/wiki/Net_capital_rule * https://en.wikipedia.org/wiki/Automated_clearing_house
> SEC net capital obligations They have to meet certain governmental guidelines on deposits vs asset price risk. > clearinghouse deposits Clearing members have to deposit money into clearinghouses as insurance in case a firm goes under.
And if it's a scaling issue, shouldn't all stocks be equally affected, rather than cherry-picking just a few?
