最新报道:Corporate insiders at major tech firms have been aggressively selling shares in recent weeks, with executives at Apple, Microsoft and Amazon offloading over $500 million in stock collectively. The sales come as the S&P 500 hits record highs, sparking debate about whether insiders are signaling concerns about overvaluation. Notably, Apple's senior VP of retail sold $75 million worth of shares - the largest single insider sale at the company in two years. While companies state these are pre-planned transactions under SEC Rule 10b5-1, some analysts warn the concentrated timing could reflect insider skepticism about current valuations.
