Aug 18 (Reuters) - U.S. stock index futures followed world bourses lower on Tuesday after Chinese shares slumped 6 percent and disappointing results from Wal-Mart.
* Wal-Mart shares fell 2.5 percent to $70.09 in premarket trading after the Dow component reported weaker-than-expected quarterly earnings and lowered its full-year forecast.

* U.S. oil prices and industrial metals, including copper, also traded near six-year lows, adding to the bearish market sentiment amid worries over China's growth outlook.
* Wall Street closed higher on Monday after strong economic data boosted the housing sector and as investors bought recently battered shares in biotech and media.
