Which stock was the most purchased by institutional investors and funds in December 2025, January 20...

The question regarding the most purchased stock by institutional investors and funds in December 2025 and January 2026 touches on a critical aspect of institutional ownership data: reporting lag.

Institutional Buying Data Availability

Comprehensive data on net institutional buying for December 2025 and January 2026 is not yet available. Institutional investors, particularly those managing over $100 million in assets, are required to file Form 13F with the SEC to disclose their equity holdings. These filings are submitted on a quarterly basis, 45 days after the end of each calendar quarter.

• December 2025: Data reflecting holdings as of December 31, 2025 (Q4 2025) will become available as funds submit their 13F filings, with the deadline being February 14, 2026. Therefore, a complete picture of institutional buying for December 2025 will not emerge until mid-February 2026.
• January 2026: As of today, January 10, 2026, January is still in progress. Even after the month concludes, data for Q1 2026 (holdings as of March 31, 2026) will not be due until May 15, 2026.

Fintel's platform tracks these 13F filings as they are submitted, allowing users to monitor institutional activity. Once the Q4 2025 filings begin to arrive in February, Fintel's "Top Institutional Buys" and "Net Institutional Buying" screens will aggregate this data to identify the stocks with the highest net purchases.

Monitor Fintel's 13F filings page for initial Q4 2025 submissions starting in early February 2026.

Monitoring Fintel's 13F filings page as submissions for Q4 2025 begin in early February is indeed the most effective way to gain insights into institutional buying trends. While the official deadline for these filings is February 14, 2026, many institutions submit their reports earlier, offering a preliminary look into their activity.

Understanding 13F Data Release

Fintel's platform is designed to aggregate and analyze these disclosures as they become available. Each 13F filing provides a snapshot of an institution's equity holdings at the end of the quarter, detailing positions, changes, and new or closed positions.1

• Early Insights: The first wave of filings can sometimes reveal significant shifts or new positions taken by prominent funds, providing an early indication of potential market sentiment.
• Aggregated Analysis: Fintel processes these individual filings to generate broader metrics such as the "Fund Sentiment Score," which identifies companies with high levels of institutional accumulation based on factors like the increase in disclosed owners and changes in portfolio allocations.1
• Full Picture: It's important to remember that a comprehensive understanding of Q4 2025 institutional buying will only solidify as the majority of filings are processed closer to and just after the February 14th deadline. This aggregated data will then be reflected in Fintel's "Top Institutional Buys" screens and other ownership analysis tools.

By actively monitoring the Fintel 13F filings page, users can observe real-time updates and leverage the platform's analytical tools to identify emerging institutional trends and potentially uncover opportunities.
