Dots mark the ranked managers' first reported quarters. Price is the split-adjusted quarter-end close, shown from Q3 2024. Coverage widened in Q3 2024 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 CMT, 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 split-adjusted changes in the quarter-end price, excluding dividends: exchange closes, checked quarter by quarter against the price the 13F filings themselves imply (value ÷ shares) and used only because they agree. They describe the stock over the period, not the return any manager earned. Phases are cut where the share of tracked managers holding CMT passed one third and two thirds of its peak.
