Last Sunday and Monday Eastern Time, two heavyweight executive resignations suddenly came to the US stock market: the CEOs of chip giant Intel and automotive giant Stellantis announced their resignations. The departures of the two CEOs highlight the challenges that both companies are facing - they are lagging behind in the fierce competition in the global automotive industry and the transformation of the chip industry. Meanwhile, these two resignations also highlight a widespread trend in the entire American business world - the "wave of layoffs" among CEOs.
