Please see below, the ‘Daily Investment Bulletin’ from Brooks Macdonald, covering the tech-led market rebound, AI investment and upcoming economic data – 12/11/2026
What has happened?
Markets rebounded over the past 24 hours, led once again by technology stocks. Strong results from CoreWeave (+24.71%) helped lift sentiment across the AI trade, with the Philadelphia Semiconductor Index (+5.66%) driving the S&P 500 (+1.31%) higher. European equities also participated in the rally, with the STOXX 600 (+0.72%) and Germany’s DAX (+1.20%) reaching fresh records. However, volatility in the technology sector has continued this morning following reports that Nvidia’s board is considering removing CEO Jensen Huang, sending shares -8.6% lower in after-hours trading. Oil prices also recovered after two consecutive declines, with Brent crude finishing +1.2% higher despite no obvious catalyst.
Investors are still hungry for AI
Anthropic’s bankers are reportedly considering a valuation of around $1.5tn for its upcoming IPO following robust investor demand, potentially allowing the company to raise more than $100bn. Meanwhile, OpenAI reportedly generated $10bn of quarterly revenue in the three months to September, up 50% from the previous quarter and taking annualised revenue to around $50bn. Taken together, the developments illustrate both the rapid commercial growth of leading AI businesses and the increasingly ambitious valuations investors are willing to support.
What does Brooks Macdonald think?
With the US holiday limiting fresh economic data and Federal Reserve commentary yesterday, investor attention is likely to shift back towards the macroeconomic backdrop. Today’s UK Q3 GDP release will provide an update on the health of the domestic economy, while tomorrow’s US producer price inflation report could prove more consequential for global markets. Expectations for interest rates remain an important influence on equity valuations, particularly in the technology sector where recent price swings have highlighted the sensitivity of markets to changes in sentiment.
