Poor global outlook won't affect economy

In terms of real economic performance, the year 2018 was "terrible" for the world. While it will take some time for the countries to publish their GDP, trade and other economic data for 2018, some major economies are expected to maintain positive growth. But the extremely volatile stock markets worldwide can be taken as a "barometer" of the world economy, and it shows that investors suffered huge losses.

Besides, the rise in primary commodities' prices, represented by oil in the first three quarters of 2018, has dealt a blow to consumers. In particular, because of the volatility of the stock markets - from China to the US to other major economies - the total market value loss last year could reach up to $20 trillion.
