Why is the S&P 500 today reacting to the Chagos Islands deal?

Markets price policy risk. The Chagos Islands deal and talk of tariffs on NATO allies raise odds of trade frictions that can cut margins and slow capex. That weighs on earnings multiples. Even without immediate changes, uncertainty adds a risk premium until leaders provide clear timelines, carve-outs, or confirm no new duties.

How could possible Trump UK tariffs affect Australian investors?

Tariffs can dent global demand and complicate supply chains. That often hits cyclicals and exporters first, then risk currencies like AUD. For Australians, consider keeping a quality tilt, watching U.S. earnings guidance, and using simple currency hedges. If rhetoric fades, risk assets can rebound, but position sizing and stop levels help manage surprises.

Is the index still in an uptrend despite the drop?

The S&P 500 today remains above the 200-day average at 6,355.80, which supports a longer-term uptrend. Short term is mixed. RSI and MACD are positive, but ADX shows a weak trend. A close back above the 50-day at 6,829.72 would improve momentum, while a break under 6,752 would warn of further downside.

What levels should I track this week?

Watch 6,752 to 6,980 as a key band from Bollinger levels. The 50-day at 6,829.72 is a pivot, and the 200-day at 6,355.80 is major support. Intraday, a push over 6,866 to 6,880 can ease pressure. Also track tariff headlines and any Diego Garcia updates for sentiment shifts.
