chonticha wat Materials was one of the top sectors in S&P 500 (SP500) this week, ending +7.69%, and the Materials Select Sector SPDR ETF (XLB) +7.73%. S&P 500 tracked +5.90%, , its best weekly performance since late June. Iron ore prices surged Friday, with futures on China’s Dalian Commodity Exchange surging as much as 6.6% to their biggest gain in more than three months, as China eased some of its COVID-19 restrictions. Analysts note, however, the tepid Chinese appetite for iron ore as steel mills have reduced production while nursing losses from weak demand partly due to a property sector slump. Relaxed restrictions also led to other commodity prices popping, along with optimism from lighter-than-expected U.S. inflation data. China’s latest updates to COVID-19 measures may mark the beginning of the end of zero-COVID policies, suggesting the weakest point of China’s commodities demand has passed. Weaker inflation numbers led to a rally in gold prices late in the five-week session, rising to the highest number in more than two months Thursday.
