The ISEPT Framework Explained
ISEPT represents a paradigm shift in pair trading by integrating visual data and continuous learning. Instead of relying on raw price series, it transforms OHLC data into candlestick chart images. These images, rich in visual patterns, are then processed by a Convolutional Autoencoder (CAE) to extract compact, meaningful latent vectors representing individual stock behavior.
These stock-level latent vectors are concatenated for each potential pair and fed into a Multilayer Perceptron (MLP). The MLP is trained to predict the next month's Sharpe ratio, a key metric for risk-adjusted returns. A distinctive feature is the Sharpe-ratio-driven feedback loop, where actual trading results from the previous month are used to retrain the MLP, allowing the model to adapt continuously to evolving market conditions. This self-correcting mechanism significantly reduces overfitting and enhances long-term robustness.
Robustness Across Market Conditions
Empirical tests conducted over a 20-year period (2004-2024) on S&P 500 constituents demonstrate ISEPT's superior performance. When combined with classic trading rules (e.g., GATEV or VIDYAMURTHY), ISEPT consistently outperforms traditional statistical baselines across all key metrics.
For instance, the Annualized Return on Investment (ROI) for ISEPT+GATEV reached 18.97%, significantly higher than the 3.52% of the standalone GATEV method. Similarly, Sharpe ratios improved markedly, indicating better risk-adjusted returns. Crucially, ISEPT maintained strong performance even during severe market stress, such as the Global Financial Crisis (2007-2009) and the COVID-19 pandemic (2020), showcasing its resilience and adaptive capabilities in turbulent times. This robustness stems from its ability to capture dynamic cross-asset interactions through image data and its continuous learning loop.

Resilience in Crisis: Global Financial Crisis (2007-2009)
During the Global Financial Crisis, ISEPT+GATEV achieved an impressive 51.63% ROI and a Sharpe Ratio of 1.24, significantly outperforming traditional methods (ROI 9.55%, Sharpe 0.50). This demonstrates the framework's ability to adapt and generate profits even in severe market downturns.
Similarly, during the COVID-19 pandemic, ISEPT+GATEV delivered 45.45% ROI and a Sharpe Ratio of 0.90, highlighting the consistent outperformance and robustness across various forms of market turbulence.
