SEBI found that these four stockbrokers as mentioned in the video had their NSE registration cancelled sometime back.

There was a possibility that these stockbrokers or their sub brokers or their relationship managers might reach out to clients and some regulatory violations may happen.

To stop that possibility, the regulator has passed respective orders to cancel their SEBI registration as well.

In such cases, if you have a demat holding or funds with such a stockbroker, you just need to approach the broking company for settlements via registered mobile number or email id only. It may take a few weeks for that to happen but your assets will be safe nonetheless.
