新加坡，10月30日 - 周五，亚洲科技股暴跌，日元上涨，债券飙升，有望创下近三年来最大单月涨幅，因为投资者担心巨大且不断增加的人工智能支出可能无法带来足够回报，纷纷涌向避险资产。
SINGAPORE, Oct 30 - Tech shares slumped in Asia on Friday, the yen rose and bonds surged toward their biggest monthly gain in nearly three years as investors scurried to safety against worries that huge and rising AI spending may not deliver sufficient returns.
谷歌母公司Alphabet股价在华尔街下跌12.6%，盘后进一步小幅下滑，市值蒸发了高达5000亿美元，因为巨额人工智能支出使该公司现金流转为负。

“市场未必在质疑人工智能建设能否获得融资，”Pepperstone分析师Chris Weston表示，“它越来越质疑，股东是否能从投入的巨额资本中获得足够回报。”此外，全球最大加密货币交易所Binance可能遭遇创纪录的黑客攻击，也让市场神经紧张，导致比特币、其他加密货币价格以及包括竞争对手交易所Coinbase在内的股票下跌。
"The market isn't necessarily questioning whether the AI buildout can be financed," said Pepperstone analyst Chris Weston. "It's increasingly questioning whether shareholders will earn an adequate return on the enormous capital being deployed." Nerves were also frayed by a potentially record-breaking hack at Binance, the world's biggest cryptocurrency exchange, which drove down bitcoin, other cryptocurrency prices and stocks including rival exchange Coinbase.
