What Is The Market Telling Us

Illumina’s shares are very volatile and have had 20 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 19 days ago when the stock dropped 3.2% on the news that reports emerged of increased competition from a Chinese rival and news of a significant legal settlement. The negative sentiment was fueled by a report stating that Chinese biotech firm MGI's DNA sequencers are gaining market share, posing a direct challenge to Illumina's core business. Compounding the pressure, the stock was also impacted by a recent settlement with the Department of Justice (DOJ) to resolve a whistleblower lawsuit. This resolution involves a significant financial payout by the company, raising investor concerns about the financial and reputational implications of the legal challenges, overshadowing any recent positive financial results.

Illumina is down 21.9% since the beginning of the year, and at $102.26 per share, it is trading 34.1% 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 $330.29.
