The closer you examine the financial sector, the more you get to believe that parts of the industry believe that if there is a way to do something wrong, why do it the right way? Not for all the firms in the market, but a few aggressive ones. And these cause regulators to go on tightening rules that finally hurt the market as the compliance costs and complexity keeps growing. The first 10 days of October saw the market regulator in an overdrive to push through long-pending reform that make the mutual fund product safe for retail investors. The speed could have some connection with the date of whole-time member Madhabi Puri Buch’s term completion coming closer, though she recently got a one-year extension. Buch has been a prime driver of change in the last couple of years and has also energized the mutual fund department into a data-crunching, evidence-building and change-enforcing machine. These are all good things for investors, of course. Three changes and what they mean for you.
