Dots mark the ranked managers' first reported quarters. Price is the quarter-end price implied by 13F filings, split-adjusted, shown from Q1 2026 where the series is continuous. Coverage widened in Q1 2026 from about a hundred managers to over a thousand, so holders and new holders are shown relative to the managers filing each quarter.
How this is calculated
13F filings are quarterly snapshots of long US-listed equity positions. They do not show exact purchase dates, intra-quarter trading, short positions, most derivatives, or a manager's actual performance. "First reported" is the first quarter-end filing that shows the position.
A manager is ranked only if we observed it filing, without BNR, within two quarters before its first position. Ranking is by the first quarter the position reached 1% of the manager's 13F book in a run of at least 2 filings, then by peak weight. "High conviction" means a peak weight of at least 5%.
Stock changes are the split-adjusted change in the quarter-end price implied by 13F filings, excluding dividends. They describe the stock over the period, not the return any manager earned. Phases are cut where the share of tracked managers holding BNR passed one third and two thirds of its peak.
