SHANGHAI (Reuters) - Investor jitters over which sectors Chinese regulators might target next spread to the spirits and e-cigarette industries on Thursday after state media ran reports about the dangers of their products, sending related companies’ shares lower. Shares in fertilizer companies were also hit after China’s top market regulator announced late on Wednesday that it would launch an investigation into fertilizer companies suspected of driving up prices. The sell-off demonstrated how investors remain on edge and on the hunt for clues about which companies might be vulnerable to state intervention, after the property, education and technology sectors were hit by Beijing regulators in recent months with unprecedentedly sweeping rules. Shares in RLX Technology Inc, China’s leading e-cigarette brand, and smaller peers Smoore International Holdings Ltd and China Boton Group Co Ltd tumbled after state news agency Xinhua published a report saying that minors were gaining easy access to e-cigarettes. Similar market sentiment took hold of liquor related stocks, after the Ministry of Science and Technology posted an article citing a study that linked alcohol consumption to cancer. China’s CSI Liquor Index closed down 1.47% on Thursday, with shares in Kweichou Moutai Co Ltd and Wuliangye Yibin Co Ltd down 1.5% and 3.1% respectively.
