   Taming the Greeks: Option Portfolios with Inductive Biases

   Wee Ling Tan, Stephen Roberts, Stefan Zohren · ARXIV · Options momentum and Greek-constrained portfolio optimization

   quant relevance 0.98

   The paper trains position signals for a systematic equity-options strategy while penalizing unwanted portfolio Greek exposure. Its reported out-of-sample performance and exposure results are relevant, but our test would use a shorter period and an approximate large-cap universe rather than historical Nasdaq 100 membership.

   Taming the Option Factor Zoo: A High-Dimensional Analysis

   Alexander Walter, Lukas Zimmer, Maxim Ulrich · ARXIV · Option-implied equity factors

   we backtested it — Sharpe -0.19 · quant relevance 0.92

   The paper tests whether option-implied characteristics add useful dimensions to long-short U.S. stock factors after controlling for equity factors. Most appear redundant in-sample, though several tail, kurtosis, and implied-volatility-convexity factors retain significant loadings. Its reported Sharpe-ratio improvement is not statistically significant.

   Self-Evolving Multi-Agent Symbolic Discovery for Financial Fundamental Analysis

   Kelvin J. L. Koa, Filip Orestav, Shengqiong Wu et al. · ARXIV · Fundamental Value

   we backtested it — Sharpe 0.41 · quant relevance 0.87

   The paper discovers interpretable fundamental valuation equations intended to identify undervalued stocks. It reports valuation-forecasting accuracy rather than measured trading returns. An investment strategy using U.S. equities can be backtested with available data, but such a test would not reproduce the paper’s cross-country evaluation.
