Is there a term or phrase for this:

Let's say something is going good for me, like Google started to like a domain of mine, or I'm doing really good with a sponsor, basically a positive thing that's going on that only I know about.

99.44% of the time when I put it out there, not so much bragging, but just sharing that there's something positive going on in my life (personal or business), the thing that was going good suddenly tanks.

Using the examples above, Google would go back to the level it was before I told anyone (sometimes it goes to worse than before), or the sponsor suddenly stops converting or retaining.

Anyone know what this is called?!
