There is a faster way to read the U.S. economy than reading the economic data. Look at the price of copper.

The metal has gained nearly 50% over the past 12 months, its strongest rolling annual advance since 2021. It is also testing all-time highs after reaching $6.52 per pound on Monday, trading just 2% below May’s all-time highs.

Copper appears to be saying the economy is booming and industrial stocks had already seen it coming.
