A "David and Goliath" story played out in the finals of our "Squawk Box Money Madness" stock tournament.
Our tournament started three weeks ago—matching up 16 of the most popular stocks on CNBC.com head-to-head, with the best playing the worst based on their 2013 performance. We ran polls each day asking the question: "Which stock will have the best gains from the start of the second quarter to the end of the year?"
Apple's recent slump made it a No. 4 seed on its side of our bracket, while BlackBerry's gains so far this year earned it a top seed on its side. BlackBerry beat Nokia, International Business Machines, and Facebook to reach the final. Apple beat Netflix, General Electric, and Bank of America.
While BlackBerry emerged victorious, the stock is only a shadow of its former self—trading at around $14 a share. It had peaked at over $230 in the summer of 2007.
