Finance & Markets News Today — October 17, 2026

US markets are bracing for a potentially tumultuous week ahead, with several major companies set to report earnings, including Capital One and Meta. The tech sector in particular is under scrutiny, with some analysts warning that recent dips in stock prices may not be a buying opportunity, citing signs of further downside risk. This caution is reflected in the continued slide of AI-related stocks, as well as a downgrade for one retail stock that had previously seen a significant comeback.

Beyond the stock market, there are concerns about the broader economic landscape, including a ballooning US budget deficit that has now reached almost $2 trillion. Against this backdrop, individual investors are grappling with complex financial decisions, such as when to take Social Security benefits in the face of uncertain health and financial futures. Meanwhile, some high-profile players, including Elon Musk, are taking steps that could reshape their businesses and influence the market. As earnings season continues, investors will be watching for clues about the health of major companies and the economy as a whole.
