With the exception of the explosive growth from 2003 to 2006, every time POC breaches a new high, it is soon followed by a big reversal. 

Are we somewhere on the repeat scale of 2003 to 2006, or is the present rise prelude to the next crash?  Who knows, but with monstrously overvalued markets, generally speaking, I suggest caution at this time.  Supply chain disruptions will not be a forever thing.
