Market Warning from Dot-Com Crash Predictor: Signs of Another Bubble Emerging
Howard Marks, co-founder and co-chairman of Oaktree Capital Management, who successfully predicted the dot-com crash 25 years ago, has issued a cautionary message to investors regarding potential signs of a new market bubble. In his latest paper, titled “On Bubble Watch,” Marks identifies several contributing factors, including excessive optimism, hype surrounding artificial intelligence, over-reliance on a select group of technology stocks known as the 'Magnificent Seven', and a bias towards index investing.
Marks emphasizes that while he does not claim we are definitively in a bubble, these indicators merit serious attention. He notes that the current market exuberance, particularly since late 2022, has resulted in high valuations for the S&P 500 that surpass those of global peers. The enthusiasm surrounding AI may also be influencing other technology sectors disproportionately.
Looking back, Marks draws parallels between today's market conditions and those leading up to the dot-com bubble. He recalls that investor behavior during bubbles often involves irrational exuberance and a fear of missing out, leading to inflated stock valuations. He cautions investors against complacency, despite acknowledging that the 'Magnificent Seven' companies involved are indeed exceptional.
Marks offers a historical perspective, explaining that many companies that once dominated the index have since declined significantly. He recognizes counterarguments that suggest current valuations, while elevated, may not reach bubble status, as the 'Magnificent Seven' might justify their high valuations through their performance. Nonetheless, he concludes that the market feels expensive and could be slightly overheated without exhibiting the extreme irrationality typical of a true bubble.
