MANILA, Philippines - This billionaire earned an extra $18.5 billion in 2014, making him the biggest financial gainer of the year, according to Wealth-X. Another billionaire, on the other hand, lost $7 billion, making him the biggest financial loser of 2014.

Wealth-X, a leading ultra high net worth intelligence and prospecting firm, said Alibaba founder and executive chairman Jack Ma added $18.5 billion to his wealth this year, bringing his total net worth to $29.2 billion. The 173 percent increase in his fortune was attributed to Alibaba's blockbuster IPO in September, and its stock's continued strong performance.
