Traders will be glad to see the back of 2018. Nearly $7 trillion has been wiped off world stocks, emerging markets have been trampled flat by a charging dollar and even gold and U.S. government bonds have lost money.

A grisly combination of U.S.-China trade tensions, central banks turning off the money taps and cooling growth in former hot spots has wiped 10 percent off MSCI¡¯s 47-country world stocks index ¡ª its first double-digit loss in any year since the 2008 global financial crisis.

Many places have fared far worse. Top Chinese shares have fallen 25 percent into ¡°bear¡± territory, export bellwether Germany has shed 16 percent, and Turkey and Argentina have led emerging markets losses, down 45 and 50 percent, respectively.
