Citigroup: Global stocks in biggest bubble since 2008 crisis

Citigroup has warned that the global stock market has entered its largest bubble since the 2008 financial crisis. The bank noted that 10 of the 18 items on its Global Bear Market Checklist have now entered the danger zone. Key risk factors cited include overvalued stock prices, optimistic investor sentiment, expanding investment in artificial intelligence (AI), and an increase in IPOs. While Citigroup's year-end market outlook remains optimistic, it cautioned that if more risk indicators emerge, a buy-the-dip strategy during a market correction could become significantly riskier.
