Homebuilder stocks rallied after the election even as analysts expected weak demand and a subdued housing market through year-end.

The brief

Stocks initially rallied on hopes for divided government, then reversed as investors reassessed economic policy and the election’s implications for the AI boom.

Nasdaq, S&P 500, Dow Jones Industrial Average, and oil prices fell for the week as support for data-center restrictions raised concerns about future AI investment.

Semiconductor stocks suffered one of their worst weeks on record, while changing sentiment around artificial intelligence put Anthropic’s proposed $1.5 trillion valuation under pressure.

Elon Musk’s political spending and administration role could face greater scrutiny from a Democratic-controlled Congress as Tesla and SpaceX encounter business pressure.

Homebuilder stocks rallied on hopes that policy changes could ease mortgage rates, inflation, fuel costs, and labor shortages, despite expectations for weak housing demand.

The episode’s central tension is a market betting on friendlier policy while investors remain wary of AI spending and housing fundamentals.
