Good point gwr,
Here are two more juniors (SGC & VIT) that I follow closely.
Sunridge Gold (SGC) has released some outstanding drill results lately, yet it trades almost identically to AUM that is also posted for comparison.
Someone yesterday asked why ECU had spiked in November. I believe the question should be why all these other juniors also spiked in the same period?
IMO, this is prime evidence of how some juniors are being shorted, probably as a hedge against the physical, or majors as Sinclair has indicated.
