The simple result of the halving is that if new supply decreases and demand stays flat (or increases), then the price will rise.
But the supply isn't actually decreasing, only the rate of production of newly mined coins. And I would suggest that there's no such thing as a free lunch in the world of finance, which means that it is NOT a given that bitcoin will increase after the next halving.
The supply to market actually is decreasing. Miners are no doubt selling some of their coins to cover overheads, debts, and take profit. The halving directly reduces the amount of miner supply available for sale.
The litecoin price after its last halving is a good example of that, and I'm glad that was brought up because it clearly shoots down the argument that bitcoin halving = major bull run.
LTC did have its halving pump. From December to April, it rose 550% against USD and 175% against BTC. Sellers distributed before the actual halving so they could sell into strength.
I was just commenting in another thread that the last halving was in July 2016, and bitcoin's price didn't start taking off in a major way until the beginning of 2017.
You're only thinking in terms of parabolic bubbles. The price of BTC doubled in the 3 months preceding the July 2016 halving.
