Why does US geopolitical risk matter for Australian portfolios?

It can move the US dollar, oil, and global credit spreads, which flow into local prices. A weaker AUD can lift unhedged offshore returns, while higher energy costs can hit margins. Policy shocks also raise equity risk premia, pulling down valuations even before earnings change.

What S&P 500 levels should I watch now?

Initial support sits near the 50-day at 6,816.70, then the lower band around 6,752. Resistance is close to 6,980.35 and the year high at 6,978.36. If ATR stays near 59, expect wide intraday ranges and plan entries and stops around those levels.

How can I reduce risk without exiting the market?

Trim high-beta positions, shift toward quality cash flows, and stagger orders. Use modest index or ETF puts as insurance, not a bet. Set alerts at key levels and respect stops. Keep position sizes aligned with volatility so a typical day does not force reactive decisions.

Does a stronger US dollar help or hurt Australians with US shares?

It can help unhedged investors by lifting AUD returns when the currency weakens, partly offsetting equity declines. Hedged investors may not get that cushion. Decide on a hedge ratio that matches your spending needs and review it regularly as policy headlines change.
