Let's say you expect a certain stock to decline like facebook because you know that Apple, who produces the most popular smartphone, will announce next week that they will no longer let apps to track you like facebook or instagram track your online activity and make privacy their first priority, which will greatly damage facebook's business model.
比方說,你預計某隻股票會像facebook一樣下跌,因為你知道生產最受歡迎的智能手機的蘋果公司將在下週宣佈,他們將不再讓像facebook或instagram這樣的應用程序跟蹤你的在線活動,並將隱私作為他們的首要任務,這將大大損害facebook的商業模式。
