The Week's Top Stock Gainers

On the bright side, it now seems almost assured that Greece will receive its next round of bailout funding and avoid a near-term, disorderly default. That's not to say that investors are settled about that heavily indebted country or the struggling eurozone as a whole, but it appears to at least be a step in the right direction. Meanwhile, in the United States, economic signals continue to be mixed, as January durable-goods orders posted a surprisingly large drop, while consumer confidence is showing some relative strength.

Throw that all together, and we ended up with a week where the S&P 500 index was up yet again but other indexes were stuck in neutral. The Dow Jones Industrial Average (INDEX: ^DJI) managed to close above the psychologically important 13,000 on Tuesday, but it couldn't hold on and ended the week roughly flat. The broader Russell 3000 had a similar experience -- posting gains during the week, but finishing out basically back where it started.

Independent oil and gas company ATP Oil & Gas (NAS: ATPG) got a big boost this week, after the company announced some positive developments at one of its well sites. On Monday, the company announced the first oil production at the "Mississippi Canyon Block 942-A-3" well and said that production rates were meeting expectations. On Friday, the company followed up with a report that the well was kicking out 7,000 barrels of oil equivalent per day, with oil accounting for 85% of the production. ATP's stock rode those positive developments to a hefty 21% gain for the week.

For business-process software company Pegasystems, it was a positive earnings report that sent the stock soaring. Interestingly, the company's past-quarter results seemed to trump its outlook, as the former looked great while the latter was a bit soft. For the fourth quarter, Pegasystems earned $0.16 per share on $115 million in revenue, well above the $105 million in revenue and $0.05 in per-share profit that Wall Street was looking for. However, as the company looked ahead to 2012, its revenue outlook topped previous Wall Street estimates, but its profit guidance came up short. Nevertheless, the stock finished the week with a whopping 23% advance.

Joining in on the big gains during the week were Cheniere Energy (ASE: LNG) and Fusion-io (NYS: FIO) . At the outset of the week, Cheniere shares jumped on the news that private-equity kingpin Blackstone is investing $2 billion in Cheniere's subsidiary, Cheniere Energy Partners (ASE: CQP) to help the company build a gas-liquefaction plant in Louisiana. Some analysts had been skeptical that Cheniere would be able to get financing for the plant, so the hefty commitment from Blackstone caused a rush for shares. That wasn't all that Cheniere had going for it this week, though, as shares jumped again on Thursday on reports that Japan may start importing U.S. liquefied natural gas. When all was said and done, Cheniere shares had tacked on 19% for the week.

For Fusion-io, the share-price tailwind came from a positive note from investment bank Credit Suisse, where analyst Kulbinder Garcha reinstated the bank's coverage of Fusion-io, slapping on a $50 price target and trouncing the rest of Wall Street's expectations for the company by estimating $527 million in revenue for 2013. Fusion-io's shares finished the week with a 14% gain.
