Shares of medical technology company Inspire Medical Systems (NYSE: INSP) jumped 3.9% in the afternoon session after the company published promising clinical data for its next-generation Inspire V system designed to treat obstructive sleep apnea (OSA).

The data, presented at medical meetings, came from a study in Singapore and a limited market release in the U.S. The results showed significant improvements, including a 20% reduction in surgical times compared to the previous model. Patient outcomes were also strong, with the Apnea Hypopnea Index, a key measure of sleep apnea severity, falling from 34.4 events per hour to 8.3. Additionally, patient adherence to the therapy was high, averaging over six hours per night. The U.S. study, which included 101 patients, reported no serious adverse events, confirming the system's safety.

The shares closed the day at $77.68, up 3.3% from previous close.

What Is The Market Telling Us

Inspire Medical Systems’s shares are extremely volatile and have had 32 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 3 days ago when the stock dropped 5.3% on the news that worries over worsening trade relations with China were triggered by critical comments from President Donald Trump. The president's tone and the suggestion of canceling a meeting with President Xi caused a rapid sell-off in the market. The trade dispute flared up after China imposed export controls on rare earth minerals, which are critical components for high-tech manufacturing. The escalation of the trade war raises concerns about supply chain disruptions and increased costs for technology companies, which are heavily reliant on global trade, leading to a broad sell-off in the sector.

Inspire Medical Systems is down 58.9% since the beginning of the year, and at $77.68 per share, it is trading 63.9% below its 52-week high of $215.42 from January 2025. Investors who bought $1,000 worth of Inspire Medical Systems’s shares 5 years ago would now be looking at an investment worth $603.90.
