Holder counts are more reliable. Implied quarter-end price ≈ $0.82. Options: 2 managers hold calls ($52.6k notional), 0 hold puts (—).

Their holding: how much the trade added to or took from the insider's holding (direct, or the trust or fund named). The same trade is sometimes reported by more than one insider, such as a fund and the director who represents it; totals count it once. A value is left blank where the reported price is far from the market price (usually a typo).
