NEW YORK, Feb 12 (Reuters) - U.S. stock index futures advanced on Thursday, following a ceasefire agreement between Russia and Ukraine and surprising stimulus measures by Sweden's central bank.
* Leaders of Germany, France, Russia and Ukraine agreed a deal to end fighting in eastern Ukraine, potentially removing a concern for investors.
* Also helping to lift futures was a decision by Sweden's Riksbank to introduce negative interest rates and launch bond purchases, while saying it could take further steps to fight falling prices.
* Stocks may get a boost from Cisco Systems, which jumped 6.7 percent to $28.72 before the opening bell after the network equipment maker reported stronger-than-expected quarterly revenue and profit.
* But Tesla Motors dropped 8.6 percent to $194.50 in premarket after the electric-car maker missed fourth-quarter sales targets and analysts' profit expectations.
* Talks over Greek debt with euro zone finance ministers failed to yield an agreement, with negotiations set to continue on Monday.
* Investors anticipate weekly initial jobless claims data and January retail sales at 8:30 a.m. (1330 GMT). Claims are expected to rise to 285,000 from 278,000 in the prior week, while retail sales are expected to have dropped 0.5 percent.

* European shares advanced, as several indexes touched multi-year highs in the wake of the Ukraine peace deal and Swedish stimulus measures.
* Asian stocks dipped amid caution over the Greek debt negotiations.
