South Korea ranked 17th in terms of the growth rate of its key stock index among G-20 member countries this year. 

According to data released by the Korea Exchange, South Korea's stock market tumbled 17-point-79 percent this year, placing it near the bottom of the ranking.

Brazil topped the list, with its key index surging eleven-point-86 percent, followed by Saudi Arabia at seven-point-24 percent and India at five-point-14 percent. 

The remaining 17 nations all posted negative growth this year. The United States saw its key index fall six-point-39 percent and Japan's major index nosedived eleven-point-eight percent.

Experts attribute the bearish market across the globe to growing global economic uncertainties mainly stemming from the trade war between the U.S. and China.
