BIIB support and resistance levels

Price found a floor near $195.91 about 6 weeks ago and has been climbing since. On the weekly chart, the next ceiling overhead sits near $400.97 — still about 82% away.

Traders commonly watch $400.97 as a target (its 78.6% extension) — think of it as a sensible next stop, not a guarantee.
That ceiling is the first place the climb might pause — worth watching how price behaves as it gets there.
There's nothing to act on here — the spot to watch was the $195.91 floor about 6 weeks ago, when price bounced there, but price has already pulled higher. What's left is the climb playing out, not a fresh starting point.
