Researchers developed WaveLSFormer, a wavelet-based Transformer model that directly generates market-neutral long/short trading portfolios from financial time series data. The AI system achieved a 60.7% cumulative return and 2.16 Sharpe ratio across six industry groups, significantly outperforming traditional ML models like LSTM and standard Transformers.
Researchers developed a new portfolio reinforcement learning method called macro-conditioned scenario-context rollout (SCR) that addresses market regime shifts and distribution changes. The approach generates plausible return scenarios under stress events and improves portfolio performance by up to 76% in Sharpe ratio and reduces maximum drawdown by 53%.
Researchers introduced TradeFM, a 524M-parameter generative AI model that learns from billions of trade events across 9,000+ equities to understand market microstructure. The model can generate synthetic market data and generalizes across different markets without asset-specific calibration, potentially enabling new applications in trading and market simulation.
