# Elastic Net Regularization ⎊ Definition **Published:** 2026-03-12 **Author:** Greeks.live **Categories:** Definition --- ## Elastic Net Regularization Elastic Net regularization is a hybrid technique that combines both L1 and L2 penalties in the model's objective function. It leverages the benefits of both approaches, allowing for both feature selection and coefficient shrinkage. This is especially valuable in complex trading environments where there may be many correlated features and a need for sparsity. By tuning the balance between L1 and L2, traders can find the optimal level of complexity for their specific strategy. It is highly flexible and robust, making it a preferred choice for many quantitative finance applications. It helps in building models that are both predictive and relatively easy to understand. This combination ensures that the model is well-protected against overfitting while remaining sensitive to the most important market signals. - [Regularization](https://term.greeks.live/definition/regularization/) - [L2 Ridge Penalty](https://term.greeks.live/definition/l2-ridge-penalty/) - [Netting](https://term.greeks.live/definition/netting/) - [Asset Class Decoupling](https://term.greeks.live/definition/asset-class-decoupling/) - [Order Flow Imbalance Analysis](https://term.greeks.live/definition/order-flow-imbalance-analysis/) - [Market-Neutral Strategy Design](https://term.greeks.live/definition/market-neutral-strategy-design/) - [Trigger Price](https://term.greeks.live/definition/trigger-price/) - [Initial Margin Requirements](https://term.greeks.live/definition/initial-margin-requirements/) ## Discover More ### [Strategic Interaction Analysis](https://term.greeks.live/term/strategic-interaction-analysis/) ![A detailed cross-section reveals the internal workings of a precision mechanism, where brass and silver gears interlock on a central shaft within a dark casing.
