Market Update: AI Frenzy Continues Amid Government Shutdown
As we head into another week, the stock market continues to ride the wave of optimism around Artificial Intelligence (AI). Despite the ongoing government shutdown, which has delayed key economic releases, investors remain bullish on the potential of AI to drive growth and innovation.
The tech-heavy Nasdaq Composite (^IXIC) led the way higher, rising 0.7% to close at a fresh record high amid an over 23% rally from AMD (AMD). The S&P 500 (^GSPC) also gained 0.4% to notch an all-time high, while the Dow Jones Industrial Average (^DJI) dropped 0.1%.
The megadeal between AMD and OpenAI (OPAI.PVT) has lifted hopes for the AI trade, with investors piling into chip stocks such as Applied Materials (AMAT), Micron (MU), and TSM (TSM). However, concerns about market concentration and speculative behavior are growing louder, with some strategists warning that valuations may be unsustainable.
