Now federal regulators are suing a brokerage firm for selling them 'unsuitable risky' and ultimately worthless investments.

I just can't own a brokerage firm — that's the only restriction that has been imposed on me.

An official at one brokerage firm that received a warrant from police said he was surprised by the lack of sophistication in some of the trades.

After four years of working in the brokerage firm, he left his position to be a curbstone broker.

At the time, the new firm had client assets of $532.1 billion, making it the nation's third largest full service retail brokerage firm based on assets.
