I don't think it was a fail, some people did make money.
I feel sorry for the ZNTR broker-dealer that was assign to ZNTR.
The MM/broker didn't do his job to protect ZNTR assets this week.
There was a lot of selling close to $20,000 not much buying
Usually their job is to protect the client best interest but
Wednesday sell was not good for MM.
I can picture the 2 CEO being upset and asking why that much 2's was sold usually there should have been a limit of buys & sells that are set so it can protect client assets.
That's why when you buy certain stocks it has a limits of shares that are available to that number that you buy and it comes out partial when you try to buy or sell the stock.
