Last fall, a brokerage firm serving both RIAs and investor clients moved to drop commissions, setting off a flurry of similar moves.
Two months later, Charles Schwab and TD Ameritrade made headlines with news that they'd reached an agreement to merge in a $26 billion deal that includes some 10,000-plus RIAs and over $5 trillion in total assets.
This development came two years after TD Ameritrade bought Scottrade for $4 billion, absorbing $170 billion in retail client assets.
