FCX, daily
TECK, daily
Summary
Suffice to add, it was a bit of a mixed day for the copper miners. Both FCX and TECK have really struggled since January. Even if copper can break >$2.70, it will take at 6-8 weeks for both stocks to have any hope of breaking a new multi-year high.
Of the the two, I personally favour TECK.
For those who prefer ETFs, there is COPX.
