What is Delta Hedging? π’
Definition: Delta hedging is an options trading strategy designed to reduce the directional risk associated with price movements in the underlying asset. This bold strategy aims to achieve a delta-neutral position, essentially ignoring which way the wind is blowing (or the stock is moving).
Delta Hedging vs Other Hedging Strategies
| Delta Hedging | Dynamic Hedging |
|---|---|
| Uses options to maintain a delta-neutral position | Adjusts hedge constantly based on market moves |
| Focuses on offsetting directional risk | Aims to respond to changing volatility |
| Requires constant monitoring | May involve less frequent adjustments |
| Can isolate volatility changes for options traders | Attempts to capture gains in shifting markets |
Examples of Delta Hedging π
- Single Option Hedging: If you own a call option with a delta of 0.6, you may sell 60 shares of the underlying stock to achieve neutrality.
- Portfolio Hedging: If your portfolio is comprised of multiple options, the combined delta is calculated to decide how many shares to buy or sell.
- Reverse Positioning: If you hold 100 shares of a stock and wish to hedge against a price decrease, you may purchase puts with a delta of -0.5.
