Pairs trading is a **market-neutral trading strategy** aimed at profiting from the relative price movements between two correlated assets. This strategy is based on the idea that some assets move together over time, and when a divergence occurs between them, traders can capitalize on their return to the common trend.

## **1. What is Pairs Trading?**
Pairs trading is a **correlation-focused strategy** between two financial assets, such as:
- **Shares of two companies in the same sector** (e.g., Apple and Microsoft).
- **Two similar commodities** (like gold and silver).
- **Two correlated currencies** (like EUR/USD and GBP/USD).
The core idea is to **buy the weaker asset and sell the stronger asset** when divergence occurs, expecting them to return to correlation again.

## **2. How Does Pairs Trading Work?**
### **A. Choosing the Right Pair**
- The two assets should have a **strong historical correlation** (for example, ETFs like SPY and DIA often move together).
- **Statistical analysis** such as **linear regression** or **cointegration** can be used to determine the relationship between them.
### **B. Identifying Entry and Exit Points**
1. **When the pair diverges**:
- Buy the cheaper asset (which has dropped in price relatively).
- Sell the more expensive asset (which has risen in price relatively).
2. **When the pair returns to correlation**:
- Sell the asset that was bought.
- Buy back the asset that was short sold.
### **C. Risk Management**
- Use **Stop-Loss Orders** to avoid significant losses if the divergence continues.
- Diversify capital across **multiple pairs** to reduce risks.

## **3. Practical Examples of Pairs Trading**
### **A. Example of Stocks**
- **Coca-Cola (KO) and Pepsi (PEP) pair**:
- Both operate in the beverage sector, so they typically move together.
- If PEP's price rises by 5% while KO remains stable, a trader can buy KO and short PEP, expecting them to return to correlation.
### **B. Example of Currencies (Forex)**
- **EUR/USD and GBP/USD**:
- If the euro rises against the dollar while the pound remains stable, a trader can buy GBP/USD and sell EUR/USD.
### **A. Example of Goods**
- **Gold and Silver**:
- They usually move together due to their correlation as safe assets.
- If gold rises sharply while silver lags, one can sell gold and buy silver.

### **Disadvantages**:
❌ **Correlation may break**: Some pairs may lose their correlation due to external factors.
