How this is scored

Direction correct: 50 points. Move error of up to 0.5 / 1 / 2 / 3 / 5 percentage points earns 50 / 45 / 35 / 25 / 10 magnitude points; larger errors earn 0. A wrong direction can still earn magnitude points. A flat close matches neither direction. Points are not returns.

Thesis

Rubrik (RBRK) closed Sep 14 at $100.20 (+15.6%, vol 5.5M) in the cybersecurity rotation as Anthropic/OpenAI CEOs urged an AI development slowdown and investors bid AI-threat defense (CRWD/PANW also double-digit). Strong Buy consensus PT ~$118.70 (~18% gap) and cyber-resilience/AI-ops positioning leave room for a 3D hold-and-grind after Tue premarket ~$97.64 (-2.6%) digests the spike. Invalidation: break under Mon low $89.12 / prior close $86.65, or a sharp unwind of the cyber bid into the Fed decision.
