Stock Market Summary – February 20, 2026

The stock market saw a volatile session on Friday, sparked by President Donald Trump’s reaction to the Supreme Court ruling against his emergency tariffs. Despite Trump’s subsequent declaration of a 10% global tariff under Section 122, the S&P 500 ended on a high.

Shares in companies negatively affected by tariffs, such as Nike, initially surged following the ruling, before dropping due to concerns Trump would impose further tariffs. The news also impacted cybersecurity stocks, including CrowdStrike and Palo Alto Networks, which fell after Anthropic announced its new tool Claude Code Security.

In the e-commerce sector, shares in Amazon, Etsy, Shopify, Wayfair, eBay, and Pinduoduo Holdings were boosted by the ruling. Trump’s tariffs have severely impacted e-commerce, leading to layoffs, price increases, and radical alterations of supply chains.

Despite an initial setback, Tesla shares were not unduly affected by the company’s unsuccessful bid to overturn a $243 million verdict in a fatal Autopilot crash suit. Meanwhile, student loan delinquencies escalated under Trump’s leadership, rising to almost 25%, compared to 9% in 2019.

Overall, the week ahead promises more earnings reports, key economic data, as well as potential repercussions from Trump’s newly declared tariffs. The current figures for Dow, S&P, and Nasdaq are not provided in these articles.
