Do Margin Call can come from buying stocks on delivery basis if my stocks fell below 90% of purchase price? do maintenance margin is required for delivery stocks?
To take a delivery trade, you require full cash. If you are buying 100 shares of a Stock A at Rs.100, this would require a cash of Rs.10,000. If the stock price falls by 10%, the it will be trading at Rs.90. This will reduce your Holding value of that stock to Rs.9,000.
There is no maintenance margin required. The cash required to hold 100 shares of the scrip is already present in the Holding value.
