Wait for pullback to $78.35. Weak momentum; also below 200-day MA (death cross), recent C-suite change — blocks BUY_NOW at $82.90. Engine's entry $78.35 (Default 5pct Sticky) is the shallowest technical level that clears the 2:1 A.R:R minimum. Key risks: Concentration risk — Customer: top-5 customers (66.0%); Sector modifier (Technology): -0.8. Chart setup: Death cross, below all MAs, RSI 39, MACD bearish. Growth is cheap relative to earnings, but the technical setup has not yet produced a breakout above resistance (PEG 0.38, quality 8.2/10, growth 9.1/10). Score 6.5/10, moderate confidence.
Passes 6/9 gates (favorable risk/reward ratio, clean insider activity, news events none recent, earnings proximity 88d clear, semi cycle peak clear, materials cycle peak clear). Fails on weak momentum and death cross (50MA < 200MA). Suitability: speculative.
