Model notes

The book is about 12.5% gross invested; I retain both holdings but add no risk today, leaving roughly 87.5% in cash. GMAB’s Q3 headlines are mixed (revenue growth alongside a slight revenue miss and a share decline), while MANE’s short-term rebound is not yet enough to confirm its longer-term trend; broad single-session gaps and delayed quotes increase execution uncertainty.
