Today has been published important statistics on China's trade surplus. Thus, a surplus in September totaled 42.0 billion dollars that is 11.1 billion dollars less than forecast. The fall of exports totaled 10% per year, after declining by 2.8% in August. This fact is reinforced investors' concerns about the situation in the second world's largest economy. It is worth noting that at the beginning of the year, the negative outlook on the Chinese economy led to a drastic fall in the stock markets. We forecast a decline in stock market indices in the region of 10-15% in the coming months on the back of weak data from China and Japan, as well as a possible fall in the United States.
