What Happened?

Shares of digital advertising platform Magnite (NASDAQ:MGNI) jumped 5.4% in the after-market session after the company announced the expansion of its high-impact ad solutions with the introduction of new Pause Ads for leading streaming providers. 

The new format will be available across major platforms including DIRECTV, DISH Media, and Fubo. Pause Ads are designed to offer contextually relevant and seamlessly integrated opportunities that improve viewer engagement for advertisers and increase value for publishers. This initiative builds on the momentum from Magnite's other ad formats like Home Screen and Tiles. Key buyers and DSPs (Demand-Side Platforms), which are systems that allow buyers of digital advertising inventory to manage multiple ad exchange accounts, set to leverage the new ads include KERV.ai, MNTN, and Yahoo DSP.

After the initial pop the shares cooled down to $25.60, up 1.9% from previous close.

What Is The Market Telling Us

Magnite’s shares are extremely volatile and have had 33 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 2 days ago when the stock gained 5.3% on the news that the company's stock reached a 52-week high, signaling strong investor confidence and continued positive momentum. The advertising technology firm's shares touched $25.30, marking a significant milestone that reflects the stock's appreciation of over 75% in the previous year. The surge highlights the company's robust performance and strong investor confidence.

Magnite is up 59% since the beginning of the year, and at $25.60 per share, has set a new 52-week high. Investors who bought $1,000 worth of Magnite’s shares 5 years ago would now be looking at an investment worth $3,464.

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.
