Democrat Midterm Sweep Impacts Investment Strategies
After the Democrats secured majorities in both the House and Senate in the U.S. midterm elections, equity markets experienced sharp initial volatility before stabilizing. Wall Street strategists advise investors not to overreact, citing a strong earnings trajectory. Key areas of concern include AI and data center stocks, which may face regulatory headwinds under Democratic leadership, and defense stocks, which could see reduced spending. Conversely, renewable energy stocks gained on expectations of supportive policies. The debt ceiling and the ongoing Iran war are additional wildcards. Analysts from UBS, Allianz, JPMorgan, and HSBC provide varied perspectives, suggesting that while near-term volatility is possible, the medium-term outlook remains largely unchanged.

Amazon App Reveals Personal Inferences to Users
The Amazon app includes a hidden 'About You' page where the company lists inferences about customers based on purchase history, Alexa interactions, reviews, and search queries. A US customer, 'fangirlinmegan', discovered this feature and shared her profile on Threads, which showed surprisingly specific attributes like 'has a flat butt' and assumptions about Kindle ownership. The post went viral, prompting other users to share their own inferred profiles, which often included remarkably accurate personal traits. Amazon states this data is used to provide relevant product recommendations and allows users to view and edit such preferences. However, this feature is not available in Germany; German users can only manually enter preferences, though data collection continues. The story highlights the extent of consumer data profiling by major e-commerce platforms.
