Nucor's stock price plummeted 5.96% during Tuesday's intraday trading session, reflecting significant investor reaction to the company's latest financial results.

The steelmaker reported weaker-than-expected fourth-quarter earnings and revenue, posting earnings of $1.73 per share compared to the analyst consensus estimate of $1.91 per share. Revenue came in at $7.687 billion, missing the expected $7.868 billion.

Adding to the negative sentiment, rising scrap steel costs are creating margin pressure for Nucor. The company's business model relies on remelting scrap to produce new steel, making it particularly vulnerable to increasing input costs even as steel prices have been rising.
