Feedback Loops in Finance

Feedback loops in finance are mechanisms where the output of a system is returned as input, potentially causing the system to amplify or dampen its original state. Positive feedback loops accelerate trends, such as when rising prices attract more buyers, which drives prices even higher.

Negative feedback loops stabilize systems, such as when a price increase encourages selling, which returns the price to equilibrium. Understanding these loops is essential for analyzing market volatility and identifying when a market has become inherently unstable.

In derivative markets, hedging activities by dealers often create these loops, as they must buy or sell underlying assets as prices move to remain delta-neutral.
