The S&P 500 index finished unchanged on Wednesday as investors were reluctant to make big bets while they waited for the outcomes of major talks involving Greece and Ukraine, but Apple helped boost the Nasdaq after an activist investor’s bullish comments.

Greek Finance Minister Yanis Varoufakis began tense talks with euro zone finance ministers on Wednesday after his new leftist-led government won a parliamentary confidence vote refusing extend an international bailout. International Monetary Fund Chief Christine Lagarde said going into the meeting that the process would likely take time.

Adding to the market’s uncertainty, the leaders of France, Germany, Russia and Ukraine began peace talks in Belarus, while in Ukraine pro-Moscow separatists tightened the pressure on Kiev by launching some of the war’s worst fighting.

The Nasdaq .IXIC was boosted late in a lackluster session by a 2.3 percent gain in Apple Inc (AAPL.O) shares after activist investor Carl Icahn issued a letter saying the iPhone maker should be valued at $216. Apple closed at $124.88.

The Dow Jones industrial average .DJI fell 6.62 points, or 0.04 percent, to 17,862.14, the S&P 500 .SPX lost 0.06 points, or -0 percent, to 2,068.53 and the Nasdaq Composite .IXIC added 13.54 points, or 0.28 percent, to 4,801.18.
