Delta Hedging: The Stabilizer of Options Trading

Imagine you bought a call options but are afraid the stock price will fall, this is when Delta Hedging comes into play.

What is Delta? In simple terms, it measures the sensitivity of an option's price to changes in the underlying asset. A Delta of 0.5 means that for every $1 increase in the stock price, the option price rises by $0.5. Call options have a positive Delta, while put options have a negative Delta.

How to hedge? The core logic is to offset risk using a reverse position. For example, if you hold a call option with Delta = 0.6, you sell 60 shares to neutralize price fluctuations—this way, the impact of stock price rises and falls on your returns is close to zero.

Difference between bullish and bearish

• call options ( positive Delta ): Hedging requires selling stocks when the stock price rises.
• Put options ( negative Delta ): When the stock price falls, hedging requires buying stocks.

Delta Differences of Out-of-the-Money/At-the-Money/In-the-Money Options

• In-the-money Options: Delta is close to ±1 (almost as sensitive as stocks)
• At-the-money options: Delta approximately ±0.5 (moderate sensitivity)
• Out-of-the-money Options: Delta close to 0 (almost no movement)

Advantages Significantly reduced risk, adaptable to various markets, able to lock in profits, can be dynamically adjusted.

Pitfalls Frequent rebalancing is required (high cost), high technical difficulty, only hedges price risk (volatility risk still exists), requires large capital.

Bottom Line: Delta hedging is not a one-time solution; it requires continuous monitoring and adjustment. Institutions and market makers use it to balance risks, but retail investors should act within their means—costs can eat into profits.
