This is how it always happens. Late Tuesday an obscure short-seller, Citron Research, announced that Twitter was the social media platform most vulnerable to privacy regulation – and its stock plunged 12% in the course of the day. All the other tech names followed, including the whole of the FANG+ Index (Facebook, Amazon, Netflix, and Google, along with a half-dozen other big names, including Alibaba). FANG+ lost 6% on the day, and MSCI’s non-Japan Asia stock index fell 1.4% overnight.
