Strategy Fragility Assessment

Strategy fragility assessment is the process of evaluating how likely a trading model is to fail under stress or changing conditions. It involves identifying the "breaking points" of a strategy, such as its reliance on specific liquidity levels or its inability to handle high-volatility spikes.

In the context of derivatives, a strategy might be fragile if it assumes constant liquidity or fails to account for the impact of its own trades on the market. By intentionally trying to "break" the strategy in simulation, developers can uncover hidden weaknesses before they lead to real losses.

This assessment is a critical component of professional risk management. It forces a realistic look at the limitations of the model.

A robust strategy is one that has been thoroughly tested for fragility and found to be resilient. It is the opposite of an over-fitted, fragile model.
