[To learn English] The explosion in the value of artificial intelligence stocks poses risks to global markets for which there is "no playbook", the CEO of Deutsche Bank's 1.1 trillion euro ($1.3 trillion) money manager DWS said, amid growing concerns that the sector is in a bubble. The AI stocks frenzy has drawn comparisons with the 1990s dotcom boom and bust, but DWS's Stefan Hoops said the recent rally was different as it was being driven by everyday retail investors – not institutions – and they had yet to be tested. 德意志银行旗下管理着1.1万亿欧元（1.3万亿美元）资产的DWS首席执行官称，人工智能股票价值的爆炸式增长给全球市场带来了风险，而应对这些风险“毫无先例可循”。与此同时，人们越来越担心该行业存在泡沫。 人工智能股票的狂热被拿来与上世纪90年代的互联网泡沫破灭相提并论，但DWS的斯特凡·霍普斯(Stefan Hoops)表示，近期的这波上涨行情有所不同，因为它是由普通散户投资者而非机构投资者推动的，而这些投资者尚未经受考验。 LearnEnglishLeave a remark
