Shanghai Enflame, a Chinese company that makes computer chips for artificial intelligence, saw its stock price shoot up 180% when it started trading on Shanghai's stock exchange. This explosive gain was so fast that it instantly turned the company's two founders into billionaires—meaning their net worth jumped above $1 billion each. The jump happened because many investors were excited about AI and wanted to buy shares in the company.
But experts are wondering whether this huge price jump can stick around. When a stock rises this fast, it's often called "market euphoria"—a time when investors get very excited and buy without thinking carefully about whether the price is fair. Once that excitement fades, prices sometimes drop just as quickly. This raises questions about whether investors who jumped in at these high prices will make money or lose it.
