Thousands of investors have made money in the current bull run in the Indian stock market. However, Arundhati Bhattacharya, former chairman of State Bank of India, expressed regret that she was not able to take advantage of the bull run. “I was chairman of SBI, which meant I knew every Indian company from the inside and hence every trade (that I would have conducted) could have been construed as insider trading,” she said at an event.
