Hold's FINRA broker-dealer (now defunct) agreed to pay the fine upon settlement. The financial statements will not "reflect the SEC fine" since Hold had a separate legal entity via the CBSX broker-dealer. The updated financials for prop firms are generally filed at the end of March (for the prior year) and generally available shortly thereafter via the SEC.gov site or from the firm itself. As dealmaker posted, traders should conduct their OWN due diligence with any firm.
There are a few others such as Avatar Securities and Quasar Trader which are still around, and both are CBSX firms. As you stated, industry regs and changes in the markets are not making it as viable for the equity prop model as before.
That was probably the most informative rant I've ever read on the internet. Thanks a lot pairsarbtooo!
I was cleaning my bookmarks before ran into this thread. Traded a few years until 11 years ago with Echo Trade. Sad to see they closed years ago.
