Copper is ripping. Traders are front-running Trump's pending decision on tariffs for refined copper imports. Everybody wants their metal inside the country before a tariff hits. So copper is pouring into the US at the fastest pace in at least 12 years. More than 200,000 tons landed at US ports in July. That's the biggest monthly haul on record going back to 2014. Prices are up near $14,000 a ton, a two-month high.

The way we'd play this isn't a miner. It's Mueller Industries (MLI). Mueller makes copper tube, fittings, and line sets for HVAC, refrigeration, and construction. That puts it levered directly to copper demand.

What separates it from a miner is the balance sheet. Mueller is debt-free and cash-rich. Its sales grew about 19% last quarter. And it just agreed to buy another copper-tube maker. So you get the copper exposure without the baggage the mining names carry.

The yen had been grinding down toward levels it hasn't touched in 40 years, and they moved to prop it up, buying yen and selling dollars to do it. The dollar had its worst day in about four years off the back of that, down roughly 3%.

That's the part that reaches us. A weaker dollar loosens financial conditions, and that's a real piece of why stocks took off yesterday and why they're still bid this morning. So the rally we're enjoying is, in part, a product of Japan defending its currency two days ago.

The reason we don't lean on it is that the move doesn't fix anything underneath. The yen keeps falling because Japan's inte
