Compare individually
Data note. Position percentages are derived from each investor's most recent SEC Form 13F filing (45-day lag), filtered to disclosed long positions only. 13F filings exclude short positions, options (mostly), foreign-domiciled holdings, and positions below the reporting threshold. Joint conviction is a descriptive sum, not a recommendation. Per HoldLens compliance: this page is factual portfolio comparison, not investment advice. Always verify against the source filing before acting.
