Market regulator the Securities and Exchange Board of India on Tuesday said that the invocation and sale of pledged shares will be a combined automated process, and this will facilitate ease of doing business as well as safeguard the interest of investors. The move comes after the regulator found that the pledged shares were lying unsold getting accumulated in demat account of brokers. Hence, the said accumulation does not serve the purpose for which pledge was invoked i.e. realisation of moneys, SEBI said.
