Tesla was one of the heaviest weights on the market and sank 3.9 per cent as it unveiled more affordable models of its Model Y SUV and its Model 3 sedan. That, though, gave back only a portion of its 5.4 per cent leap from Monday, when speculation rose that the electric-vehicle maker may be set to announce a new car.

Oracle also dragged the market lower. It fell 2.3 per cent after a news report suggested it’s making thin profit margins on a key line of business related to artificial-intelligence technology.

The frenzy around AI has been one of the biggest trends guiding Wall Street to record after record recently. It’s been so strong that it’s raised worries that prices have potentially shot too high across the market.

Overnight, IBM rose 1.7 per cent after announcing a partnership that will integrate Anthropic’s Claude AI chatbot into some of its software products. Advanced Micro Devices rallied another 3.4 per cent to add to its surge from Monday, when it announced a deal where OpenAI will use its chips to power AI infrastructure. Dell rose 3.7 per cent after executives talked up the company’s opportunity for growth because of AI at an investment conference.
