Although we think the trend in prices is down, and have since before the China weakness, problems in the wind turbine biz, electric vehicle sales slowdown etc. etc. became widely apparent, in the immediate term the fact the futures did not go much below $3.63 and have popped back to $3.70+ is a tell that something is afoot. $3.6955 last, after rising from 3.6270 to $3.7195 in a day.
Here's the one-year chart (daily prints) via FinViz:
Our guess is the strength comes from one of two sources: 1) China was buying again as the yuan weakened, essentially turning financial reserves into physical commodities as they have been doing with oil or 2) and potentially more ominously, the commercial hedgers (green line on lower panel of chart) have been closing short positions and may even be going long the futures. We'll have to wait for the next Commitment of Traders report to see the positioning.
A quick note on the COT, it is not a very reliable timing indicator but over longer time frames it proves up the general rule of futures trading: the large and small traders (the specs) can steal some cheese from the cat, (the commercials) but in the end the cat must win or the whole game stops. And the problem arises from the asymmetry of outcomes: when the cat loses, it loses its cheese. When the mice lose they can lose their lives. Or at minimum get bloodied for their trouble.
Just something to be aware of.
