I dont think we can see 600 this month price is stable but anything can happen
I agree that the price is very stable right now as it is holding the same for the last two week and holding given a flucuation of $10-15~ at the beginning of Christmas time with boxing day and all.
Don't expect anything to happen until the Chinese new year is over.
Not all Chinese thing and activities can manipulate the price unlike before. But anyways we can see the effect of that event during a week when it will occur.
