Deconstructing the financial reports of the five major tech giants: Why has AI suddenly lost its popularity? Following the "darkest moment" experienced by the "seven tech giants" in the US stock market last week since ChatGPT ignited the AI market, the tech stock market experienced a rollercoaster ride this week. Taking Nvidia as an example, on July 30th, the stock fell 7% at one point, but surged nearly 13% overnight. On August 1st, Nvidia fell again, closing down nearly 7%. The Nasdaq index, mainly composed of technology stocks, also followed suit, with a weekly decline of over 3.8% as of the close on August 3rd.
