) -- Stocks finished Monday's pre-holiday shortened session with losses as "fiscal cliff" talks in Washington remain stalled.

Discussions over striking a budget deal before the Jan. 1 deadline aren't likely to resume until Thursday at the earliest as Congress and President Obama take a Christmas break.

Sen. Joe Lieberman said over the weekend that "it's the first time that I feel it's more likely we'll go over the cliff than not," following House Speaker John Boehner's failure last week to get Republicans to follow his back-up plan on the so-called fiscal cliff.

"Hopes faded long ago for anything meaningful coming out of this fiscal cliff debate, but now we're seeing downright pessimism in the market," said Sonny Tahiliani, managing director at MacroMoves. "Lawmakers may want to revisit the CBO's projections on the hit to GDP and seek to connect the dots, because risking a recession inside of an output gap is dangerous territory. The Fed will be forced to act in a bolder way should compromise fail to materialize."
