Smart,
Because of the history of broking fraternity,everyone considers brokers as these demons out there to make fast money, even at the risk of the clients.
Not everyone is the same, but what retail doesn't understand is that there are lakhs of clients looking at loopholes to make a fast buck at the risk of the brokers. This never comes out, because we as brokers don't really have a forum to share database of defaulters today in India.
The problem with letting a client trade on a demat without POA is that, it becomes very similar to letting a client trade without money in his account. When we started our business, we had said that you can transfer even from other demats using DP slips and sell it with us. The issue was, suddenly there were cases where the stocks were not getting transferred in the right amount of time, mainly because of the regulatory infrastructure available in India( I know TP hates me mentioning India is underdeveloped, but if you work as a broker , you will know that underdeveloped is an understatement). We as brokers would get forced by the client, who would show us the proof of transfer to let him sell shares. There were clients who would sell it and if they see any price movement upwards, also sell it with another broker who has the POA and have the shares debited instantly from his demat. The DP slip he has given us would then bounce(similar to margin cheque) and we would be stuck with a short position and the auction penalty on our head. We stopped this process immediately.
SPEED e is very interesting and we are hoping that the systems will be stable enough in the next few months that we can tell all our cleints that they can map any demat of theirs to both buy and sell..
Can you also message me this broker you are talking about, PM? I can figure out the best practices, which might help us to offer the same...
