Stock market today: Dow, S&P 500, Nasdaq futures sink as Iran launches strikes in face of Trump warning

The S&P 500 is experiencing a compounding bearish signal: a pre-existing technical downtrend from 6946 to 6506 (-6.4% over ~3 weeks) is now layered with a high-severity geopolitical shock as Iran launches strikes despite Trump warnings. The combination of technical deterioration and event-driven risk typically produces gap-down opens followed by elevated intraday volatility. Monthly sigma of 1.22% appears understated given current conditions — geopolitical shocks historically compress implied vol estimates while realized vol spikes 2-4x. The current price at 6506 is approaching a key zone where 2025 breakout consolidation occurred (~6400-6500), and a breach would open a technical target toward 6200-6300. ⚡ DEEP SONNET: For short/hedge positions: current levels acceptable with geopolitical premium embedded; for defensive long entry, wait for stabilization near 6300-6400 with confirmed volume capitulation. Avoid chasing gap-downs at open. | TP:4.5% SL:2.5% | 3-10 trading days for geopolitical resolution or escalation clarity | Risk:HIGH — Triple risk overlay: (1) geopolitical escalation uncertainty with Iran strikes potentially drawing broader regional conflict, (2) existing technical downtrend already in force before this catalyst, (3) elevated starting valuations limit defensive buying support. De-escalation remains a tail risk to the downside thesis, capable of triggering sharp +2-3% reversal within 24-48 hours. | Sizing:CONSERVATIVE
