Reconstructed holdings
The portfolio reconstructed from this member's disclosed Purchase and Sale trades: net shares valued at the latest close (2026-07-10). Sizes come from disclosed amount ranges, so share counts, values, and weights are all estimates.
Net worth
Estimated from the ranges in the member's annual financial disclosures: the band runs from the sum of disclosed asset minimums less liability maximums up to the sum of asset maximums less liability minimums. Only electronically filed reports are read — a missing year means no electronic filing, not zero net worth.
