The 10% owner's near-total liquidation dwarfs the director's sale and is a rare, high-conviction signal of fundamental concern or strategic exit. Monitor for a formal 13D amendment or press release explaining the sale; the stock may face sustained selling pressure as the market absorbs the overhang.
