Pres. Obama's re-election doesn't bode well for the odds of a tax holiday on overseas cash, notes Eric Savitz. That's problematic for large-cap tech names such as Apple (NASDAQ:AAPL), Microsoft (NASDAQ:MSFT), and Cisco (NASDAQ:CSCO), which respectively have $83B, $54B, and $42.5B stashed overseas (per their most recent financials). As Savitz observes, there's a good chance some of that cash will be used on foreign acquisitions, especially in light of recent deals such as Microsoft/Skype and Cisco/NDS.
