Dynamic Graphs Predict Institutional Equity Holdings with High Accuracy

Summary

Researchers introduce the first benchmark for institutional equity holdings prediction using temporal graph machine learning, framing it as node affinity prediction. The NAVIS model achieves state-of-the-art accuracy, outperforming other dynamic graph and heuristic methods, with temporal and structural signals being key.

This paper establishes the first benchmark for predicting institutional equity holdings by leveraging temporal graph machine learning. The task is framed as node affinity prediction on a discrete-time temporal bipartite graph, constructed from SEC Form 13F filings that detail investment managers' portfolio decisions and securities. Using a dataset of 99 managers and S&P 500 stocks over 48 quarters, the Node Affinity prediction model using Virtual State (NAVIS) achieved a state-of-the-art Normalized Discounted Cumulative Gain (NDCG) of 0.9127. This significantly outperforms all other dynamic graph representation learning competitors and heuristic methods. Interestingly, domain-specific node features provided only marginal gains, suggesting that the temporal and structural signals within the 13F ownership graph are the primary drivers of predictable information, highlighting the strong persistence in institutional portfolios.

Why it matters

Investment professionals and quantitative analysts can gain a significant edge in forecasting institutional capital flows and modeling future demand for securities, leading to more informed investment strategies and risk management.

How to implement this in your domain

  1. 1Explore the NAVIS model and temporal graph machine learning techniques for portfolio allocation and holdings prediction.
  2. 2Integrate SEC Form 13F data into a dynamic graph database for analysis.
  3. 3Develop predictive models based on node affinity prediction to forecast institutional investment behavior.
  4. 4Benchmark current forecasting methods against temporal graph models like NAVIS for improved accuracy.
