## Put-Call Ratio Analysis

The put-call ratio is a technical indicator derived by dividing the trading volume of put options by the volume of call options. In options trading, this ratio serves as a gauge of market sentiment regarding the future direction of an underlying asset.

A high ratio suggests that traders are buying more puts than calls, often indicating bearish sentiment or hedging activity. Conversely, a low ratio indicates higher demand for calls, suggesting bullish sentiment.

Contrarian analysts look for extreme levels in this ratio to signal potential market tops or bottoms. When the ratio reaches an abnormally high level, it may indicate excessive pessimism, suggesting a potential price floor.

The ratio is essential for understanding how derivatives traders are positioning their portfolios against volatility.
