IEX premarket price against the prior close.

Indexes closed higher as oil slid and yields retreated; premarket trading is mixed.

Tone

The S&P 500 closed up 1.14%, the Nasdaq 100 1.73%, the Dow 0.59% and the Russell 2000 0.51%. Premarket, the S&P 500 is 0.25% lower and the Nasdaq 100 0.18% higher. Dow and Russell 2000 premarket prices are not in yet. The S&P 500 structure score is 44, Balanced: the medium trend is up, the short-term setup less so, and neither side has a clear edge.

The rally came as oil slid and yields retreated, even with a 25 basis point Fed rate hike. One newer story flags the ten-year yield at 5% as pressure on growth stocks. Jensen Huang said Nvidia's chip sales will double next year, news that backs the AI trade leading the Nasdaq 100. Generac led the S&P 500 leaderboard after an $8 billion AI deal with Amazon.
