As the U.S presidential primary season begins to heat up, Netflix(NFLX) - Get Report is getting ready to premiere the fourth season of its popular House of Cards series on March 4.

To get everyone in the proper, "Inside the Beltway," wheeling and dealing frame of mind, the online streaming company just released the first official trailer for the new season.

"You have no idea what it means to have nothing," says Frank Underwood, played by the actor Kevin Spacey, as the trailer begins. "I have had to fight for everything my entire life."

Do those words remind you of anyone in particular on the current campaign trail? Maybe more than one U.S. presidential candidate?

Should be an eventful House of Cards season this year.

Shares of Netflix, based in Los Gatos, Calif., closed Thursday at $86.35, a decline of 2.4%.

Cisco Systems(CSCO) - Get Report shares rose by 9.6% to $24.68 at the close of regular trading before the company released better-than-expected results for its second fiscal quarter.

Shares were rising slightly in after-hours trading after Cisco reported strong earnings of 57 cents per share and revenue of $11.9 billion, beating analysts' expectations.

The company, based in San Jose, Calif., is a holding of Action Alerts PLUS, the charitable trust portfolio managed by TheStreet's Jim Cramer.
