There's a lot of bluster this election year about the economy and President Barack Obama's effect on jobs and the stock market. But what you may not realize is that many comparisons aren't exactly fair.

Yes, in November 2008 when Obama won the election, unemployment was just shy of 7%, and when he took office in January it was under 8%. But comparing our current unemployment rate of 8.3% to what things were like when the president took office isn't so simple. After all, the financial crisis was really only beginning in late 2008, and the Great Recession didn't peak until mid-2009.

In many ways it's an accident of timing that Obama has presided over a rise in unemployment more than anything else. It doesn't take a rocket scientist to understand that a previous administration's policies were in action for those first readings and Obama's plans hadn't had time to take shape.

The same can apply to the stock market. The bottom of the bear in equities came in early March 2009. So in many respects President Obama "bought the bottom" and has simply presided over the rebound. The market is up about 55% since Jan. 20, 2009, and a handful of equities are up by dramatically more than that.

Of course, the five-year run for the S&P 500 is a loss of 8%, so we haven't even gotten back to pre-crash levels yet. Let's not pretend Obama ignited a stock market boom.

Still, investors are addicted to crunching numbers and tracking time frames. So I've decided to offer up some of the biggest winners since Obama took office in January 2009.

I could have included the losers, too, but there would be too many tied for losses of 100% via bankruptcy, ranging from the recent failure of Borders to victims like General Motors (GM), which went to zero but then got a second life with its 2010 IPO after Chapter 11 reorganization.

Instead, here are the 10 biggest winners under Obama, even though he personally deserves little credit for these success stories:

1. Dollar Thrifty Automotive Group (DTG), up 5,740%
2. Jazz Pharmaceuticals (JAZZ), up 3,570%
3. Pier 1 Imports (PIR), up 2,750%
4. Cardtronics (CATM), up 2,090%
5. Pharmasset (VRUS), up 2,471% based on its buyout by Gilead (GILD) that was completed Jan. 16 at $137 a share.
6. Boise (BZ), up 1,560%
7. Dana Holding (DAN), up 1,460%
8. Crocs (CROX), up 1,390%.
9. Valassis Communications (VCI), up 1,230%
10. Ulta Salon (ULTA), up 1,160%

Keep in mind that these figures are as of the Feb. 2 open and just a little difference in share price can really alter these returns, considering the long-term change.

I'm not sure whether there are any lessons to learn from this list, either. But at least I hope you find it interesting.

And if you're not a fan of Obama or his impact on the economy, perhaps hearing about another Obama-backed green-energy company going bankrupt will be more to your liking.
