How do US-Iran tensions affect stocks in the short term?

US-Iran tensions typically raise risk premia and volatility. Investors rotate toward defensives, while cyclical and oil-sensitive sectors often lag if crude firms. Liquidity can thin and spreads widen around headlines. We watch support and resistance near recent bands and use limit orders, modest size, and predefined stops to manage intraday swings.

What are the key signposts beyond Iran nuclear talks headlines?

Track official statements, verified intelligence updates, and energy supply indicators. Watch crude term structure, shipping insurance costs, and US yields. On equities, monitor breadth, volume versus average, and reactions at Bollinger bands and moving averages. A sustained break with confirmation at the close often matters more than the first headline print.

How should Hong Kong investors think about oil prices today?

Higher oil can pressure transport and consumer margins while supporting energy producers. For HKD portfolios, consider staggered entries, reduce leverage, and use energy-linked funds to hedge exposure. Avoid market orders during volatile windows. We reassess after closes near key index levels, adjusting sector weights as crude and yields stabilize or extend moves.

Is ^GSPC still in an uptrend despite geopolitical risk?

Medium term, the index trades above its 200-day average, which supports an up-bias. However, RSI near neutral and ADX showing no strong trend point to range behavior. We respect support near 6850-6800 and resistance near 6950-7000. Escalation in US-Iran tensions could break the range, so confirmation at the close is key.
