Reflexivity
Perception rewrites the thing
The Alchemy of Finance
Textbooks say prices reflect fundamentals. This piece asks why Soros says the arrow runs both ways, and how that loop manufactures a bubble.
What actually happened?
The Alchemy of Finance turns on a two-way arrow. Market prices always distort the underlying fundamentals — and the distorted price then changes the fundamentals it was supposed to be reflecting. The mechanism is concrete. The share price rises, so the company raises money at a better valuation, acquires more cheaply, hires more easily, and the results genuinely improve, which confirms the rise. The participants' bias has entered reality through the price. Markets are not forecasting the future so much as helping to make the one they forecast.
First check whether the loop is connected
Reflexivity is not everywhere. Whether price can rewrite the fundamentals depends on the pipe: funding, hiring, customer confidence. Where the pipe is wide — finance, property, platforms — trends make themselves true. Where it is narrow, a price move does not improve the product.
A startup's valuation is part of its product quality: a high mark hires stronger people and the product really does get better. Reading only today's product reads half the loop.
A self-feeding error can outlast you
If perception can manufacture reality for a while, then the market is wrong is not by itself a reason to trade against it. Mispricing feeds itself through the loop and can stay funded longer than your margin lasts. Soros often rode the thing and watched for the leak.
Shorting or leaving the moment a sector looks overheated usually dies halfway up. Overheating brings real funding and real growth. Wait until the price starts hurting the business.
The turn comes when the loop bites back
Self-reinforcement always has a limit: high prices start crushing buyers, high valuations start forcing fraud, expansion starts burning through the cash. The point where positive feedback becomes negative is the trend's expiry date. Watch the sign of the effect, not the level of the price.
The sector is still rising, but new customers are worse and collection is slower. Price up, loop already turned around and biting. That is the exit signal.
How do I use it today?
Where you are: you have decided something is overvalued and you want to trade against it.
Ask first: does this price have a pipe into the fundamentals? Is the loop still feeding itself, or has it started biting back?
Where it goes wrong: using reflexivity as an excuse to buy any bubble; or going short while the loop is still thick, and being right about direction while dying on timing.
