Aluminium Futures

If there is any Logic why Nalco shot up today, maybe someone preempted the move higher in Aluminum futures. Big swing higher, and I am thinking it can start wave V of 3. Wave IV broke the channel for wave 3 but did not overlap with wave I high, so the wave count remains intact. Wave III=I and is not extended in which case V=I near 2780 is like a normal projection. If one of the impulse waves is expected to extend then we should see the move in wave V surprise us on the upside. Let's see.
