Possibility of a buyback will always be there. It's just for you to know how to spot that. While this isn't a financial advice, let me put it out there that every psychological level (that's the zero levels –100,000, 110,000, 120,000, 130,000 etc) are where price will often find resistance for a few days before breaking out of them. These are levels traders like to short from and most of them profit from such.

So, that pullback those levels afford the market is where most shrewd investors like to jump in.
