Quantitative strategies are investment approaches that use mathematical models and statistical techniques to identify trading opportunities. These strategies analyze historical data to predict future price movements, allowing investors to make informed decisions based on numerical evidence rather than intuition. Typically employed by hedge funds and institutional investors, quantitative strategies can include algorithmic trading, risk management, and portfolio optimization. By leveraging technology and data analysis, these strategies aim to enhance returns while minimizing risks, making them a popular choice in the financial markets.
