Weekly Momentum Watch: Top and Bottom UK & US Stocks

Below is a snapshot of top and bottom momentum stocks for the week, separated by UK and US companies.

🇬🇧 UK Momentum Stocks

Among the top UK momentum stocks this week, Hochschild Mining and Fresnillo continued to benefit from broader strength in commodities markets, with precious metals and base-metal price movements supporting mining sector performance. Precious-metals and copper miners generally saw rebounds as metal prices recovered from earlier dips, underpinning gains in major resource names on the FTSE 100. Continued industry-wide metals support was noted in market reports tracking mining equities.

Relx Plc is among the lower momentum names this week, and some analysts believe developments in AI are not going to help the company but rather threaten to hinder its performance.

🇺🇸 US Momentum Stocks

In the US, top momentum stocks were predominantly in the technology and semiconductor space. Western Digital reported fiscal Q2 2026 revenue of roughly $3.0 billion, up about 25 % year-over-year, supported by demand for data storage products, while gross margins and operating income also improved.

Micron Technology continued to show strength linked to elevated memory demand as the company focuses on AI and data-centre markets.

Among the bottom momentum names in the US, Tyler Technologies recently reported 2026 revenue expectations slightly below consensus estimates.
