Each disclosed stock purchase buys the midpoint of its reported range at that day's close, and sales sell it; returns are time-weighted and include dividends. Members report ranges rather than exact amounts and can file up to 45 days after a trade, so this is an estimate, not Blumenthal's actual return. Based on 6 holdings as of Nov 11, 2026.
