Delta is delta in options, which indicates the sensitivity of the option to changes in the underlying asset, and delta is defined as the ratio between the change in the option and the change in the spot of the underlying asset.
The formula for calculating delta is:
delta = change in option spot of the underlying asset.
When it comes to specific applications, it can be understood in the following way:
The delta of a call option is positive, typically in the range of 0 to 1. This is because the call option is also in the case of the underlying asset. For example, if the delta is 05. When the underlying asset is 1 unit, the call option may be 05 units.
Put options have a negative delta and typically range from -1 to 0. This is because the put option will fall when the underlying asset is in place. For example, if the delta is 07. When the underlying asset **1 unit, the put option** may drop by 07 units.

What is a delta neutral strategy?
A delta-neutral strategy is an options trading strategy that aims to maintain a delta value of the entire portfolio at or near 0 by constructing a specific portfolio of options positions, regardless of the movement of the underlying asset**. Delta is a measure of the sensitivity of an option** to changes in the underlying asset**, so the goal of a delta-neutral strategy is to eliminate or reduce the impact of changes in the underlying asset** on the value of the portfolio.
Common delta-neutral strategies include the following four ways, with 50 ETFs as the underlying asset:
1.*1 call option + sell delta 50 ETF
2.*One put option + 50 delta ETF
3.Sell 1 call option + 50 delta ETF
4.Sell a put option + sell a delta 50 ETF
The goal of these combinations is to bring the overall delta close to zero through a combination of option positions and the underlying asset. In this way, regardless of the underlying asset, the value change of the entire portfolio will be relatively flat, reducing the directional risk.
Delta neutral hedging can be divided into two forms: static hedging and dynamic hedging
1.Static hedging: After the initial position is opened, no adjustments are made. This means that the investor maintains a relatively fixed delta neutral status throughout the position until ** or otherwise decides to close the position.
2.Dynamic Hedging: Dynamically adjusts the portfolio to market changes throughout the holding period to maintain a delta of 0 or approximate 0. This may involve frequently selling or selling the underlying asset to accommodate market volatility.
Dynamic delta-neutral strategies typically require more frequent adjustments, which is a common and effective trading strategy for options liquidity service providers.
The purpose of the delta-neutral strategy
There are several key aspects to the purpose of the delta-neutral strategy, which aims to take full advantage of the characteristics of options and make a profit from them through the management of the Greek letters such as delta, theta, vega, and gamma:
1.Take advantage of the time recession (theta gains):
Delta neutral positions are not affected by small changes in share prices, but option premiums are still affected by time recession. By constructing a delta-neutral strategy, investors can take advantage of the diminishing value of time to earn theta yields. Even if the stock price is relatively stable, the option premium will decrease over time, resulting in returns for investors.
2.Take advantage of volatility changes (vega returns):
A delta-neutral position can profit from an increase or decrease in volatility without significant changes in the stock price. With the right** change in market volatility, investors can earn positive VEGA returns when volatility rises, increasing the value of their portfolio.
3.Constructing an Explosive Options Trading Strategy (Gamma Gains):
Although delta neutral positions are not affected by small share price movements, they can take advantage of highly volatile market conditions. Since delta moves in the same direction as the stock price changes, investors can obtain gamma returns by correctly guiding the market, so as to achieve profits when the stock price fluctuates significantly.
4.Protect positions from short-term volatility:
Delta neutral hedging can be used to protect positions from small** fluctuations. Especially for investors who hold for a long time, this strategy can provide some protection and allow the position to continue to profit in the face of short-term market volatility.
By maintaining a delta of zero, the Delta Neutral Strategy aims to hedge against the impact of stock price fluctuations on open positions, while maximizing portfolio returns by managing other Greek letters and taking advantage of factors such as time, volatility, and market direction.
