A lot can be said about institutional investors in a publicly listed company and how their investments vary with change in the management. Over the past six months a lot has changed at Bombay House, the headquarters of Tata Sons, the holding company of many Tata group entities. Although the reason behind the ouster of former chairman Cyrus Mistry is not clear, investors first rushed in to increase their stake in select group companies when Ratan Tata made a comeback as acting chairman of Tata Sons. With Natarajan Chandrasekaran at the helm now, mutual funds are yet again changing their holdings in the group companies.
