Nvidia Corp.'s stock volatility has sparked concerns about the sustainability of its growth. Despite valuation and competition worries, the key factor is the durability of demand for AI accelerator chips. The company's revenue doubled last fiscal year to $61 billion, driven by high demand for AI chips. Bullish investors believe demand will continue to increase as more companies utilize artificial intelligence for business expansion and efficiency. However, bears are skeptical about AI's potential returns on investment. If demand cools, Nvidia's high valuation could face a reckoning. Some experts fear AI may not live up to the hype, drawing comparisons to the telecom industry's overinvestment in the 1990s. While some remain bullish on Nvidia due to ongoing spending by tech giants like Microsoft and Amazon, analysts caution about future uncertainties. Micron Technology's disappointing forecast highlights the unpredictability in traditional markets, emphasizing the need for careful monitoring of Nvidia's fundamental momentum.
