There is no hedge fund involved with IFUS. hedge funds follow a strict procedure forbidding investment in anything under $5 per share and, for most hedge funds, $10 per share. Your comment about a "wash trade" is totally preposterous and only made out of abject ignorance or malicious intent. Wash trades do not occur in 100,000 share blocks.
That big a trade is almost certainly a dump by an insider getting rid of their now unrestricted shares. The only IFUS financials DO NOT show any increase in sales or revenue, but a substantial decrease. In fact, revenue is down 19% from 2023. Since Walther will not get the reports audited, it6 may be down substantially more than that.
BTW, where are the "Scientific reports" you want us all to swallow?
