Tripled the stock market
False.
There are different stock market indexes, but none of them "tripled" between 2010 and 2016. Also, while 2008 was a historical low, the overall growth trend has been steady since the 1930's -- so we can't really say his result was exceptional.

The Dow Jones index went from ~8,000 on January 20th, 2009 to about ~16,500 today, February 22nd, 2016, which is double and not triple.
Its maximum range is almost a triple: the Dow hit a minimum of 6,627 in March 2009 and a maximum of 18,273 in May 2015. This, though, is cherry picking.

Cut unemployment in half
True, but the initial figure was clearly exceptional. As you can see it went from 10% to 5% after growing from 4.5% to 10% after the 2008 mass layoffs. Since many of these layoffs were skilled workers, it stands to reason that the figure would go down naturally as they find new jobs.

Ended two wars
True. The two wars intended here are the Iraq war and the war in Afghanistan. This is only true related to the United States involvement. Iraq was left in a state of civil war and Afghanistan is also unstable, and still sees the presence of US troops.
Cut the uninsured rate in half
False. The uninsured rate is lower than 2009 according to Gallup, but certainly not half.

Brought gas prices down to $2.75
False.
According to the EIA the current price is $1.834 per gallon, much lower than that. However it's not correct to say he "brought gas prices down", because the prices were very similar in 2009-2010, six years ago.

Cut the annual Bush deficit by two-thirds.
False.
While Bush did have a huge deficit on the last year of his presidency (more than $1.4 trillion) because of the banks bailouts, the rest of his tenure was between positive $0.1 trillion and negative $0.5 trillion, which is well in line with Obama's best result in 2015, around $0.45 trillion in the red.

Got Bin Laden
True.
On May 2, 2011, bin Laden was shot and killed inside a private residential compound in Abbottabad, where he lived with a local family from Waziristan, during a covert operation conducted by members of the United States Naval Special Warfare Development Group and Central Intelligence Agency SAD/SOG operators on the orders of U.S. President Barack Obama.
