A saying that has had some staying power is "If looks could kill". If someone wants to generate enough ill will and project it towards another that would cause a disruption of their communication and while it wouldn't kill in most cases it certainly would disrupt.
The collapse of a smooth interchange of ideas would be brought about.
The market as a whole is subject to shocks as are individual stock issues, where the turbulence connected to the idea of the stock or the market and the reality of the them has been disrupted.
Thus where you have easily defineable interchange flows from the investor public to each other and the company to its shareholders you get predictable and rather measureable and constant price patterns - and where they have been disrupted you should find in one form or another a "look that kills", and a collapse of the wave function of interchange.
In using technical analysis this is theory that might be speculated about as to causes and effects.
