The SEC will scrutinize some investment advisers.

Securities and Exchange Commission Chairman John S. R. Shad said the investing public may be bilked to the tune of $90 million a year by some financial planners. Commission investigators are expected to conduct 1,150 inspections of investment advisers this year--a 125% increase over 1981. Inspections are targeted at firms that pose the greatest risks to investors--such as those that hold clients’ securities and funds and those that have custody or discretionary authority over clients’ assets or have financial interests in products sold to clients, Shad said.
