Sinclair, Wiley, Napco, Jabil, and Mirion Stocks Trade Down, What You Need To Know

What Happened?

A number of stocks fell in the afternoon session after investors rotated out of AI-linked high-flyers following underwhelming earnings updates from Oracle and Broadcom as the core thesis shifted from "growth at any cost" to "prove the returns." 

Oracle triggered the alarm by missing revenue estimates while simultaneously hiking capital expenditures by $15 billion. This reignited fears that AI infrastructure spending is outpacing actual monetization. Broadcom compounded the anxiety; despite beating earnings, its stock fell as CFO Kirsten Spears cautioned that gross margins may come under pressure as product mix shifts further toward system-level AI sales. This sparked a macro rotation away from AI infrastructure and power plays.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Mirion (MIR)

Mirion’s shares are very volatile and have had 21 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 11 days ago when the stock dropped 2.6% on the news that a director, Lawrence D. Kingsley, sold 300,000 shares of the company's stock. 

The shares were sold for a total value of about $7.15 million. This sale represented a notable transaction by a key insider. Following the sale, the director's direct ownership in the company was reduced. Significant stock sales by company insiders can sometimes cause concern among investors regarding the company's outlook, contributing to downward pressure on the stock price.

Mirion is up 47.2% since the beginning of the year, but at $24.90 per share, it is still trading 16.3% below its 52-week high of $29.75 from October 2025. Investors who bought $1,000 worth of Mirion’s shares 5 years ago would now be looking at an investment worth $2,371.
