The idea worth investigating
A small-cap research paper reports a 100.1% cumulative net return and a 2.33 Sharpe ratio for its selected 2025 configuration, with an 18.3% maximum drawdown. It combines news sentiment with macro signals and holds positions for 40 trading days. The interesting question is whether the stock-selection rule adds more than the language model.
Authors’ simulation, one 2025 test year; best row selected across multiple configurations. Includes the paper’s 100 bp cost scenario plus fixed 5 bp one-way slippage.
