Reflexivity
Soros's principle that market prices influence the fundamentals they are supposed to reflect, creating self-reinforcing or self-defeating feedback loops.
Definition
Reflexivity describes situations where investor expectations alter the underlying reality they're trying to forecast: rising stock prices ease a company's cost of capital, validating the rally; falling currencies trigger inflation that justifies the depreciation.
Reflexive episodes are unstable by construction — they accelerate until a constraint binds, then reverse with similar violence.
