What Is The Market Telling Us
Illumina’s shares are very volatile and have had 20 moves greater than 5% over the last year. But moves this big are rare even for Illumina and indicate this news significantly impacted the market’s perception of the business.
The previous big move we wrote about was 21 days ago when the stock dropped 3.4% 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.
Illumina is down 7.6% since the beginning of the year, and at $121 per share, it is trading 22% below its 52-week high of $155.15 from November 2024. Investors who bought $1,000 worth of Illumina’s shares 5 years ago would now be looking at an investment worth $413.14.
