A billionaire investor warns the S&P 500 is overheated because the Mag 7 stocks trade at extreme valuations. He points to 2000, when Cisco, Microsoft, and GE all topped $600 billion in market cap. Cisco never recovered to that size. High multiples create a wall that stops further gains.
circa 2025, we cannot go into the S&P. Okay. What makes you say the S&P is overheated? If you look at the Mag 7, it's way above the S&P long-term average, right? When the multiples become high, it becomes difficult. You hit a kind of a brick wall. This isn't the first time we've seen this story play out. In the year 2000, there were 3 stocks that were over a $600 billion market cap: Cisco Systems, Microsoft, and GE. We know where— how that story ended. Cisco never saw that market cap again. Too euphoric investing in the largest market caps in a time of euphoria isn't a great recipe for success.
