Why did the S&P 500 fall today?

An oil price spike tied to Middle East risks boosted inflation worries and pushed traders to price rate cuts later. That kept yields firm and hit equity multiples. A break below the 200-day moving average also weakened technical support, inviting systematic selling and fading dip demand.

What does the 200-day moving average break signal?

A sustained break below the 200-day moving average often signals a weaker trend and can trigger mechanical selling. It lowers confidence in rebounds and raises the bar for positive catalysts. We look for a quick reclaim on strong breadth and volume before adding risk meaningfully.

How do delayed rate cuts affect Canadian investors?

Delayed cuts can keep U.S. yields and the U.S. dollar firm, which pressures growth stocks and supports cash-generating cyclicals. In Canada, energy and materials may offset weakness in tech or rate-sensitive banks. Mortgage and borrowing costs could also stay higher for longer than hoped.

Which sectors look relatively resilient now?

Energy and materials appear better positioned if oil stays firm and input prices hold. Defensive growth with steady cash flow, healthcare, and dividend growers can also help. We are cautious on high-duration tech and small caps until yields ease or the index reclaims the 200-day moving average.
