[Lack of Positive News, Volatility Remains the Main Theme]: On the macro side, Trump's tax reform bill narrowly passed the House of Representatives and was sent to the Senate for review. US Treasury yields pulled back from recent highs, and the US dollar rose on Thursday after three consecutive days of decline. LME copper dropped slightly. On the fundamental side, from the supply side, the current warrant drawdown was significant, but warehouse inventories did not decline as expected. As of Thursday, May 22, SMM copper inventories in major regions across China increased slightly by 700 mt from Monday to 139,900 mt, up 7,900 mt from last Thursday, marking inventory buildup for two consecutive weeks, although the buildup this week was less than last week. On the demand side, with copper prices falling yesterday, transactions at lower prices were brisk. Currently, low-priced supplies have been largely purchased, and it is expected that the center of the premium will struggle to rebound today. On the price side, with no more positive news in the market, it is expected that the upside potential for copper prices will be limited today.
