Following a fresh round of intense sell-offs, the US AI sector saw a technical rebound on Monday (October 19). The Philadelphia Semiconductor Index ended an eight-day losing streak, at one point surging over 3% before closing up 1.6%. On the same day, Goldman Sachs upgraded cloud computing company CoreWeave from "Neutral" to "Buy," and several Wall Street analysts also voiced strong support for the fundamentals, leading to a partial dissipation of the "AI capital expenditure peak" panic that had permeated the market. However, analysts cautioned that hedge funds' total exposure remains high, and deleveraging risks have not been fully cleared. Market sentiment remains divided on whether this rebound signifies a true bottom.
