Which hedge funds and institutional investors hold UNP?

Accepted Answer

StonkWhisper tracks 13F filings submitted to the SEC by institutional investment managers with over $100 million in assets. The whale tracker for UNP shows which major funds hold positions, their portfolio weight, share counts, and how those positions changed quarter over quarter.

Question 2

What does conviction level mean for UNP whale holdings?
