These 5 Companies Own 17% of Citigroup's Stock

The owners of Citigroup (C 0.46%) haven't had a smooth ride over the last decade. The New York City-based company went into the financial crisis as the biggest bank in America, with an appropriately large bottom line. But it emerged from the economic cataclysm in shambles, after writing off tens of billions of dollars' worth of toxic subprime-backed securities.

It's likely for this reason that all five of Citigroup's biggest shareholders are institutional money managers -- overseeing others' investments but not their own. For instance, Vanguard and Fidelity make the list thanks to their mutual and exchange-traded funds, which own large swaths of the stock market at any particular point in time.
