UnitedHealth (UNH) is attracting a wave of institutional buying in Q2. Berkshire Hathaway (Warren Buffett) added roughly 5.03 million shares, Dodge & Cox about 4.73 million, David Tepper’s fund near 2.27 million (some sources show 2.45 million), and Renaissance Technologies about 1.35 million. Michael Burry and Saudi Arabia’s Public Investment Fund appear to have bought call options — a leveraged way to express upside. With Q2 13F filings still streaming in, this pattern suggests major investors see durable cash flows from UNH’s Optum and insurance franchises. But 13Fs lag and are an incomplete record; use them as a research starting point.

Reader Reaction: Why Timely 13F Updates Matter
Several readers thanked Vivek for the 13F updates , a reminder that timely, curated SEC filing summaries are valuable to retail investors and journalists. Form 13F shows long U.S. equity holdings reported by institutional managers each quarter, offering glimpses of who is rotating into or out of sectors. The catch: filings are quarterly and filed within 45 days of quarter-end, so they reflect past positions rather than real-time trades. They also don’t show shorts or many derivatives, and managers can hold positions in multiple vehicles. Use 13F alerts as idea generators, then verify with the raw filings and company fundamentals before acting.
The Count Debate: Berkshire vs Appaloosa and How Filings Vary
A reader corrected the thread, pointing out Berkshire holds 5.03 million UNH shares and Appaloosa shows 2.45 million , a useful reminder that aggregated totals can differ. Discrepancies arise because aggregators interpret 13F data differently, rounding rules vary, and managers sometimes report via multiple funds or subsidiaries. Amendments and late filings also change totals. When precise share counts matter , for ownership percentages, dilution calculations and governance narratives , check the original SEC 13F filing on EDGAR. For broader trend-spotting, a few hundred thousand shares rarely flip the headline: institutions are clearly leaning into UnitedHealth.
Tracking the Whales: Using WhaleWisdom and SEC Filings
The thread referenced WhaleWisdom, a popular tool for parsing 13F data. Sites like WhaleWisdom, Dataroma, and GuruFocus consolidate quarterly SEC filings and let you track which funds bought or sold a stock. They make it easy to spot trends, sort by change in position, and peek at net values, but they each refresh at slightly different times and may interpret data differently. For final verification, use SEC EDGAR and the raw 13F filings; if you trade on this intelligence, combine it with earnings, fundamentals and risk analysis. Remember: aggregated data creates narratives, but due diligence confirms them.
