I exited today @ 16.50. Too much resistance on M/D. 31% on call option.
Decided to persist with this long trade, possibly due to spinoff creating some more additional value, and zinc stockpiles declining(slowly). Some favourable data came in saying that western world demand for zinc is high (despite Chinese exporting a fair bit)
Maybe someone a bit more patient can eek out a few more % here. Sometimes a few % is worth it. $17 is a tough call as I agree a lot of resistance. All dependent on zinc price fluctuations this stock.
