3. JPMorganMorgan Stanley ( MS) is the lead banker on Facebook's IPO, but JPMorgan ( JPM) entrenched itself as the No. 2, which could mean bigger things down the line for its investment banking division. IPOs bring in big fees for banks, which are precious at a time of weak trading revenue thanks to stricter regulations. JPMorgan isn't known for bringing technology companies public, so being ahead of Goldman Sachs ( GS) in underwriting Facebook was a real coup. Last year, JPMorgan purchased a significant stake in Twitter, so perhaps the tech juggernaut will keep rolling under CEO Jamie Dimon and his banking team. Shares of JPMorgan have gained 9% this year.
