A prescient call that Citigroup was undercapitalized pushed the financial analyst into the spotlight. But before her words moved markets, she built her reputation on years of tough, accurate calls. Clients know her for warning in 2005 that the rise in subprime borrowers could spark economic woes; for calling Bear Stearns shares worthless at $30; and for predicting early in '09 that financials would rally. Her latest call may test her track record: She downgraded Goldman Sachs to neutral.

No hierarchy: Her staff gets to meet everyone who stops by, like John Thain.
