What this means for BDSX
BDSX is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is a single insider acting alone. Who is buying. The most credible buyer in this window is a 10% Owner ($1M–$5M). That insider’s track record: past buys beat the S&P 500 3 of 4 times (avg +30% vs S&P over 6 mo). Overall credibility score: 21/100 (Low).
