Exxon (NYSE: XOM) announced this morning that its second quarter income doubled from a year ago to $7.56 billion thanks to rising oil prices.

This marks Exxon’s largest quarterly profit since 2008 when it made $14.83 billion thanks to record oil prices. Oil prices dipped thereafter sending Exxon’s profits lower. Oil prices formed a bottom in the first half of 2009 so the rebound in oil since then enabled Exxon to double its earnings from a year ago.

A year ago in the second quarter it made 81 cents per share and made $1.60 per share in this year’s second quarter.

These results beat analyst expectations of earnings of $1.46 per share.

Exxon shares are trading up 0.61% before the opening bell.

Leading stock market losers today though is Vista Print (NASDAQ: VPRT), which is trading down almost 30% before the open on negative earnings results.

Vista Print announced that its revenue grew 22% from a year ago in its last quarter and is booking year over year revenue growth of 30% on $670 million dollars.

However, Vista guided down on expectations for the next 12 months of earnings. It now says it expects to make $1.65 to $1.80 per share on revenue when analysts had been expecting it to be able to make $1.83 per share. That news is causing Vista shareholders to dump the stock this morning.
