#美股AI概念股全线反弹 #Gate广场中秋团圆局 U.S. AI Stock Market: A Rebound or a New Starting Point? Which of the four AI stocks—TempusAI, Super Micro Computer, Astera Labs, and Arm—has the best prospects?

1. Market outlook: Treat it as a “rebound” for now, not a “new uptrend”
September 17 ended the U.S. stock market’s three-day losing streak, with the Nasdaq up +1.69% and AI stocks broadly recovering. But this was merely “bad news exhausted + oversold rebound”: the Federal Reserve may still hike rates once more before year-end, so interest-rate pressure has not been lifted; Arm just plunged about 40% in one week, showing that high-level positions are highly vulnerable.
Whether the rebound can turn into a reversal depends on three things:
First, whether the rebound can last 2-3 days without breaking below the previous low;
Second, whether U.S. Treasury yields stabilize;
Third, NVIDIA’s next earnings report.

2. One-sentence assessment of the four stocks

Astera Labs (top pick): Revenue grew +104% year over year, the company is already profitable, and its Q3 guidance far exceeded expectations, making its fundamentals the strongest.
Arm (great company, expensive price): It has the strongest moat in chip IP, but its P/E ratio is about 270x. After its recent plunge, wait for a pullback before buying.

Super Micro Computer (a turnaround bet): The cheapest, with a P/E ratio of about 19x and a clear recovery in gross margin, but it has financial governance blemishes and high volatility.

Tempus AI (theme play only): It rose the most today (+14.85%), but the move is sentiment-driven; it is still loss-making, and the CEO has reduced his holdings, so it is suitable only for short-term trading.

3. Summary

If choosing just one, pick Astera Labs; for a high-risk, high-return bet, choose Super Micro Computer; wait for a pullback in Arm; treat Tempus as a theme play. Treat the current move as a rebound, build positions in batches, and set stop-losses.
