The anticipated decrease in earnings for Nucor in Q2 2024 is primarily attributed to lower average selling prices in its steel mills segment, a significant part of its business. Although there's a modest volume increase, it's not enough to offset the impact of lower prices. The steel products segment is expected to follow a similar trend, which could negatively affect investor sentiment and stock price in the short term. However, the positive outlook for the raw materials segment might provide some cushion to the overall negative impact.
