Wait — supporting gate not met yet. Price is at or below entry $1228.95 but weak momentum still blocks BUY_NOW. Key risks: Sector modifier (Technology): -0.8; Negative momentum. Chart setup: No clear chart pattern; technical signals are mixed. Growth is cheap relative to earnings, but the technical setup has not yet produced a breakout above resistance (PEG 0.92, quality 8.3/10, growth 10.0/10). Score 6.4/10, moderate confidence.
Passes 7/8 gates (favorable risk/reward ratio, clean insider activity, no SEC red flags, news events none recent, earnings proximity 55d clear, semi cycle peak clear, materials cycle peak clear). Fails on weak momentum. Suitability: aggressive.
