Sell if holding. At $8.49, A.R:R 0.9:1 is below the 1.5:1 minimum. Reward from here is too thin for a buy — the engine flags exit. Additional concerns: V7 low-quality RISK_OFF penalty: -0.5 (Q=4.2); Sector modifier (Basic Materials): -0.1. Chart setup: Death cross, below all MAs, RSI 35, MACD bearish. Score 4.7/10, high confidence.

Passes 6/9 gates (clean insider activity, no SEC red flags, news events none recent, earnings proximity 28d clear, semi cycle peak clear, materials cycle peak clear). Fails on weak momentum and favorable risk/reward ratio and death cross (50MA < 200MA). Suitability: speculative.
