The arbitrage trading strategy #套利交易策略 aims to capture temporary market inefficiencies and pricing errors through precise calculations, rapid execution, and strict risk hedging, achieving stable returns with low risk. Its forms are diverse, ranging from nearly risk-free spot-futures arbitrage and ETF arbitrage to statistical arbitrage and merger arbitrage that rely on statistical models and risk management.

**Key Points:**

* **Price difference is key:** Focus on relative value rather than absolute prices.

* **Hedging is a means:** Strip away systemic risk and expose to specific price difference risks.

* **Speed and scale are barriers:** Opportunities are fleeting, and small profits must rely on volume to succeed.

* **Low risk ≠ no risk:** Various risks exist in reality, and poor management can lead to losses.

* **Technology-intensive:** Highly reliant on advanced technology platforms and quantitative models.

Arbitrage strategies are important "lubricants" and efficiency enhancers in mature financial markets, but due to their technical thresholds and capital requirements, they mainly become a playground for professional institutional players. For individual investors, understanding and identifying arbitrage opportunities can help deepen the understanding of market pricing mechanisms, but direct participation in high-difficulty arbitrage requires extra caution.
