I doubt it. They don't have enough votes to form a government and their usual partners, Pasok, are refusing to form a coalition without Syriza. The most frustrating thing about this whole mess in Europe has been the lack of resolve to actually make a decision, from the people and the governments--all of them.

It's a moving target but close to the end:

New Democracy will receive 29.53% of the vote, equivalent to 128 seats.
Syriza will receive 27.12% – 72 seats.
Pasok will receive 12.2% – 23 seats.
Independent Greeks will receive 7.56% – 20 seats.
Golden Dawn will receive 6.95% – 18 seats.
Democratic Left will receive 6.23% – 17 seats.
Greek Communist Party will receive 4.47% – 12 seats.

However, the upswing in optimism on Friday was due to the European powers-that-be saying they had a plan to flood the banks with liquidity in the days following the election if an anti-austerity government was formed.

I get the feeling now that our fortunes are cast and although the stock price might bump up and down, the end result is not dependent on the mess in Europe. It would have been better, obviously, if the European market were strong at this point in time but we are dealing with majors that are used to making very long-term decisions.
