Why did the S&P 500 fall today?

S&P 500 today slipped mainly because tech weakened. A Microsoft selloff on AI capex concerns hit mega-cap sentiment and pulled growth lower. Investors also waited for Apple’s results, which kept risk light. Outside tech, moves were more mixed, with defensives steadying and energy selective rather than strong.

How does Microsoft’s selloff affect the index?

Microsoft is a large S&P 500 weight, so big price swings have an outsized impact. When Microsoft falls on AI spending worries, other mega-cap tech often follows. That drags the overall index, narrows breadth, and can push investors toward value, dividends, and cash until earnings or guidance ease the concern.

What should Australian investors watch tonight?

Watch Apple’s results and guidance on demand, services, and capital plans. If tone is upbeat, tech may stabilise; if cautious, rotation to defensives could extend. Track key S&P 500 levels around 6,866 and 6,980. Also monitor the Aussie dollar, as currency moves can sway local returns on US assets.

Is this pullback a buying opportunity?

It can be, but timing matters. Look for evidence that selling is slowing, such as holds above support near 6,866 and improving breadth. Consider scaling in rather than going all-in. Focus on quality names and diversified ETFs. If Nasdaq declines continue, patience and staged entries can reduce regret.
