Tech Stock Rebound Boosts the Major Indices to Close Higher
On August 25, the three major US stock indices closed higher. The S&P 500 rose 0.32% to 7,677.28 points, the Nasdaq increased 0.66%, and the Dow Jones Industrial Average gained 0.30%. A simultaneous decline in oil prices and U.S. Treasury yields alleviated market concerns over inflation and long-term interest rates.
Semiconductors and large-cap technology stocks were the primary drivers. Ahead of NVIDIA's earnings report, investors rebuilt some positions in tech stocks, with AI supply chain companies like Micron and AMD strengthening.
Declining Yields Temporarily Ease Valuation Pressure
High long-term interest rates reduce the present value of future cash flows for growth stocks, which is why the previous surge in Treasury yields significantly suppressed technology stock valuations. After two consecutive days of falling yields, SPY gained some breathing room.
However, this does not mean interest rate risks are over. The U.S. PCE is a key inflation indicator closely watched by the Federal Reserve. If core PCE exceeds expectations, the market may once again raise expectations for rate hikes or delay easing measures, potentially leading to a rebound in both yields and the dollar.
Two Key Events to Determine Short-Term Direction
NVIDIA's earnings report will test whether AI capital expenditures and profit growth can support current valuations. If earnings and guidance significantly exceed expectations, technology-weighted stocks could drive the S&P 500 to continue its advance. Conversely, if the market experiences another scenario of "good earnings but a falling stock price," the index could also be dragged down.
The PCE data will determine the macroeconomic valuation environment. A moderate reading would favor further yield declines and support risk appetite, while surprisingly high inflation would suppress SPY again.
Key Price Levels
The S&P 500 is currently near its highs, with the 7700-point level acting as a near-term psychological resistance. If the index breaks through and stabilizes above it, the market may continue to test higher targets. If the event outcomes fall short of expectations, the 7650-point area will face the first test, with deeper pullbacks requiring attention to previous breakout zones.
The quality of this rally depends on whether the gains broaden beyond a few AI leaders to more sectors. If cyclical stocks, financials, and consumer sectors show synchronized improvement, the index trend will be more solid. If only a handful of tech stocks provide support, volatility risks will remain high.
