Bruker’s $30M Trim: When a Stock Slide Becomes a Social Catastrophe

Grandeur Peak didn’t just trim a position – they committed a cardinal sin of investment etiquette. You don’t just leave a 3.69% holding in a life sciences darling. You don’t reduce your stake to 0.15% and expect to be invited back to the 13F AUM mixer. It’s like showing up to a wedding in a tank top – technically allowed, spiritually offensive. Now Bruker’s relegated to the “also bought a toaster” section of their portfolio, while NASDAQ:MPWR gets 8.05% of assets like it’s the guest of honor.
