Biogen: first window hit, breakeven stop — next target is week 8

Biogen is at week 6 of a buy signal with a +1.62% gain since entry and the stop now at breakeven: trade risk is technically zeroed out. The first model window has been reached this week; the next — a 20% trim — is scheduled at week 8. The setup profile is balanced but not an acceleration: medium strength, limited room before a key resistance overhead.
