US stocks fluctuated higher but fell back in late trading, brief analysis of TSMC, AMD, and Apple stocks

On the 14th, the three major indices showed basically the same intraday trend, all fluctuating upwards before falling at the close. Goldman Sachs, JPMorgan Chase, and others reported Q3 revenues exceeding expectations, with year-on-year growth, indicating a market recovery driven by economic soft landings, mergers and acquisitions, and IPOs. Of course, it also shows that trading income benefited from market volatility, such as interest rate cuts and tariff trade policies.

However, Trump's trade-related remarks—"The U.S. is considering terminating trade in edible oils and other products, and pointed out that the U.S. can produce edible oils domestically and does not need to import"—pulled the rally back down.

$Taiwan Semiconductor(TSM.US) opened lower on the 14th but climbed steadily afterwards. Multiple parties exited at the close, resulting in a 2.29% drop.

It followed the broader market trend intraday, with reduced trading volume. Earnings forecasts are optimistic, and with potential earnings catalysts, it may break through the resistance level of 308 and test 310.

$AMD(AMD.US) showed a "rally and retreat" trend on the 14th, surging strongly at noon but failing to hold gains in the afternoon, closing slightly down 0.77%.

After partnering with OpenAI, AMD also collaborated with Oracle. Oracle Cloud Infrastructure will deploy 50,000 AMD GPUs starting in Q3 2026, with gradual expansion in 2027 and beyond. The competition between NVIDIA and AMD remains intense, with AMD partnering with all of NVIDIA's collaborators one by one. From the perspective of diversified partnerships and computing power demand, this is a welcome development.

Short-term moving averages still provide support, and partnership news may sustain a sideways trend. However, if it falls below 210, downside risks may be tested.

$Apple(AAPL.US) showed a small V-shaped recovery in the morning session on the 14th, then fluctuated between 246-247. It briefly surged to 248 at the close but weakened, closing up 0.04%.
