Holdings

Market-wide 13F leaderboards for a quarter — which stocks were most bought, most sold, most initiated or most exited across all 13F filers versus the prior quarter. Mover deltas are restated onto today's split basis; ordering is by change in published position value. Values normally use report-date closing prices, may fall back to filer values, and can be zero when unavailable; the delta therefore includes price movement, not just net buying or selling.

bucketstring nullable

The requested leaderboard: top-buys, top-sells, new-positions or sold-out-positions.

reportDatestring date
previousReportDatestring date

The prior available report quarter; omitted when no earlier row exists.

coverageStartDatestring date

The first report quarter with complete 13F corpus coverage.

isWithinCoverageboolean

False when the requested report date predates complete corpus coverage.

comparisonAvailableboolean

True when both the target and prior report dates are inside complete coverage.

isRankingAvailableboolean

True when this comparative leaderboard can be returned for the requested quarter.

comparisonUnavailableReasonstring nullable

Why comparison data is unavailable; null when comparisonAvailable is true.

True while the target quarter's 13F filing window is still open. Figures then use a combined view: filed funds contribute their current rows, while non-filers carry prior-quarter rows at zero delta so only reported moves rank.
