Why Roku (ROKU) Stock Is Trading Up Today

What Happened?

Shares of streaming TV platform Roku (NASDAQ: ROKU) jumped 4% in the afternoon session after the company announced the launch of its connected TV advertising platform in Brazil and unveiled a series of product updates, including new AI-powered voice features.

Alongside the expansion, Roku rolled out software updates that introduced artificial intelligence to its voice search, allowing users to ask more complex questions about shows and movies. The platform also added new sports features, such as live scores and game reminders. Additionally, Roku released new hardware, including new streaming sticks and a new Roku-powered projector available at Walmart.

The shares closed the day at $98.56, up 4.5% from previous close.

What Is The Market Telling Us

Roku’s shares are very volatile and have had 29 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 5 days ago when the stock dropped 3.5% on the news that President Donald Trump threatened to impose 'massive' new tariffs on Chinese goods. 

In a post on his Truth Social network, Trump stated that his administration is calculating a 'massive increase of Tariffs on Chinese products.' Trump targeted China's tightening controls on rare earth metals, which are vital components in many technology products from electric vehicles to defense systems. The threat immediately impacted the market, with the tech-heavy Nasdaq sinking 2.4% and the broader S&P 500 falling 1.7%. Such tariffs could significantly disrupt the global supply chains that many technology companies rely on for manufacturing and components. The policy uncertainty also raises fears of retaliatory measures from China, which could impact sales in a key international market for many U.S. tech firms, leading to investor concern over future profitability. 

Earlier in the week, China announced new export controls on the critical minerals. Beijing's Commerce Ministry stated that foreign suppliers now need government approval to export products containing certain rare-earth materials. These materials are essential for producing high-tech goods, including computer chips, electric vehicles, and defense technology. Analysts viewed the move as a strategic assertion of China's dominance in the global rare earth supply chain, particularly amid ongoing trade tensions.

Roku is up 32.3% since the beginning of the year, and at $98.58 per share, it is trading close to its 52-week high of $104.84 from October 2025. Investors who bought $1,000 worth of Roku’s shares 5 years ago would now be looking at an investment worth $435.29.

Unless you’ve been living under a rock, it should be obvious by now that generative AI is going to have a huge impact on how large corporations do business. While Nvidia and AMD are trading close to all-time highs, we prefer a lesser-known (but still profitable) semiconductor stock benefiting from the rise of AI.
