Similar to my earlier post, might as well look at the recent litecoin halving too
Litecoin had its first halving on 25 August 2015

This is quite different to the first bitcoin halving but in both cases there has been what looks like a large speculative bubble followed by higher price afterwards.
In Litecoin's halving the bubble peaked before the actual halving date and was not enough to approach all time highs in litecoin. Although litecoin normally has its own all time highs roughly in sync with bitcoins movements, this halving occuring at a time when litecoin was already at a very depressed price and bitcoin is still well below its own all time high.
But the essence of my idea remains that the halving may induce a bubble as part of the price discovery mechanism.
