Commodity prices have climbed this week, with oil, silver, and copper among the more recent standouts, buoyed by China’s stimulus measures, but traders should be wary about the outlook for the sector until they see evidence that the global economy will avoid a hard landing.

UK shares slipped on Wednesday, retracing gains from the previous session, as investors questioned whether the optimism over extensive stimulus measures in China was overdone.
