Stock market today: Dow pops higher, Nasdaq and S&P 500 slide amid rate-cut fears

The mixed performance of the stock market suggests volatility, especially in the tech sector which is heavily influenced by interest rate expectations and bond yields. Tech stocks like Nvidia and Apple faced declines due to fading optimism about rate cuts, although more stable sectors like utilities and health care seem to benefit. However, rising oil prices could impact consumer spending and overall inflation, raising further concerns for tech valuation.

Rising oil prices could be beneficial for energy stocks, as they are expected to benefit from supply concerns and higher prices. Brent crude exceeding $81 per barrel is indicative of tighter supply and increased demand, particularly in Asia. This trend may lead to bullish sentiment in the energy sector moving forward.

The decline in Moderna's stock following a bleak sales forecast indicates a negative short-term sentiment towards biotech stocks, especially those heavily reliant on pandemic-related products. With demand decreasing, investors may seek to pull back from MRNA which could lead to further declines unless new catalysts surface.
