If Brian Mast still holds everything they disclosed buying. Disclosures do not report sales proceeds or current positions, so a stake sold last year still counts here — this is an upper bound, not a profit. Purchases are sized at the midpoint of the disclosed bracket, and dividends, fees and taxes are not included. 30 purchases have no market price and are left out. More on the limits.

A backtest, not a forecast. Every purchase gets the same stake because filings disclose a range, not a size. It ignores their sales, dividends, fees and taxes — each of which flatters the result, and 30 purchases could not be priced and are excluded.
