Economist Steve Hanke has issued a warning about a stock market bubble, pointing to a $10 trillion rally driven by Big Tech. The surge, according to Hanke, is accompanied by record-high call option volume, a signal of speculative frenzy.
Hanke's caution comes as major technology stocks continue to power market gains, raising concerns about overvaluation. The economist highlighted the sheer scale of the rally, which he described as a $10 trillion phenomenon, without providing a specific timeframe.
