Stocks are set for a small gain Friday as oil prices head higher and investors lessened their worries on Ukraine and Greece, CNBC reported.

The Dow Jones Industrial Average touched 18,000 for the first time since Jan. 31, 2014. Additionally, the NASDAQ opened at its highest level since March of 2000.

Greece has agreed to meet with European Union representatives, the European Central Bank and the International Monetary Fund before a key Eurogroup meeting on Monday.

"The tone of the negotiations (between Greece and the euro zone) heading into Monday seems constructive," said Art Hogan, chief market strategist at Wunderlich Securities.

Ukraine and Russia are expected to enter into a ceasefire agreement Sunday. This positive news sent both U.S. and European stocks higher Friday.

Stocks in focus:

With oil headed higher Friday, Chevron shares traded up over one percent to about $112.19 per share.

Zynga, the maker of games like Words with Friends and Farmville, met analysts' expectations in their fourth quarter earnings but did not impress investors. The company hoped the Words with Friends update would have attracted more engagement by users, but it did not. The company is expecting a loss for this current quarter.

Microsoft shares are trading higher by over 1 percent. The software maker is set to unveil Windows 10 later this year and is already giving out a preview to those who want to try the new features. In late day trading, the stock is up to about $43.59.

World Wrestling Entertainment (WWE) is up over 16 percent. The entertainment company that shows live pro wrestling reported a loss of just 1 cent per share on $140 million in revenues. Both of those figures were above expectations, Yahoo Finance reported. WWE has gained over 1 million subscribers to their $9.99 per month WWE Network cable channel in less than one year.

Twitter shares are up almost 1.5 percent to $48.61. The stock, which was getting hammered the past few months, is recovering in the past two weeks. It hit a low of $36.68 back on Jan. 29 and has been climbing ever since. On Feb. 5 the stock was at $41.26, then on Feb. 6 it spiked to $48.01.

Do you think WWE can continue to trade higher or is Friday's leap just a one-day wonder? Will Twitter keep climbing? What about oil? Leave us your thoughts below and let us know.
