8月4日，必和必拓公司盘中上涨4.42%，报87.47美元/股，成交额6799.76万美元。多种金属与采矿板块整体走强，泰克资源涨6.15%、HudBay Minerals涨6.79%、力拓涨3.46%。
消息面上，必和必拓西澳黑德兰港工人工会此前正式宣布计划于8月8日实施24小时装船禁令，次日再进行24小时全面停工，预计影响多达16艘货船装载作业。黑德兰港为全球最大铁矿石出口港，每日中转必和必拓约8000万美元铁矿石。澳大利亚公平工作委员会已安排于8月4日就此事举行听证会。这场持续逾七个月的劳资纠纷是2000年以来必和必拓铁矿石港口业务面临的最大规模工会行动，市场对铁矿石短期供应中断的担忧推动板块走强。
