BOSTON – A wave of IRA rollovers over the next four years could spark a significant increase in separately managed accounts (SMAs). According to the Financial Research Corp.(FRC), by 2008 money rolled over into IRA accounts is expected to deliver more than $50 billion annually in SMA net flows. Through SMAs, investors can own stocks or bonds selected by a money manager but unlike a mutual fund, there is a feature that allows holdings to be customized. FRC reports that nearly $2 from every $5 invested in SMAs will come from an IRA rollover. Of the $500 billion in SMAs in 2003, roughly 45% were held in IRAs. An estimated 25% of the $30 billion in net flows to SMAs came from IRA rollovers. Nearly 93% of firms customize less than 25% of their SMA client accounts, according to FRC. The firm is expecting that percentage to increase as a result of wider adoption of unified management account platforms and savvier technology that offer advisers the opportunity to view a client's entire investment makeup.
