If you have brokerage account with them, it may be wise to transfer the stocks you have to another brokerage. In theory, the stocks you have just like your money in the bank but without FDIC insurance and you don’t know if BS still have them physically :). At least that’s my take and I can be wrong.
There’s a special kind of insurance called SIPC that gets involved whenever a brokerage fails, it will attempt to give you your stocks back, even if the brokerage did not have them in physical possession when it failed. It’s not as bulletproof as FDIC though.
