Nancy Pelosi's stock tracker lit up social media on Monday, this time shining a spotlight on Senator Markwayne Mullin (R-Okla.) and his timely purchases of Amkor Technology Inc. (Amkor Technology (AMKR)) stock. The tracker noted that Mullin "is on a roll," having bought up to $150,000 in Amkor shares twice in 2026—once on January 5 and again on February 4. The transactions were reported to the public on February 4 and March 2, respectively, meaning there was a lag of weeks between the trades and their disclosure.
What makes this particularly interesting is Mullin's role on the Senate Armed Services Committee, which oversees the military supply chain and military installations. As the tracker pointed out, that committee has direct oversight of defense contractors and semiconductor supply chains—and Amkor is a key player in chip packaging and testing. The implication is that Mullin may have had access to non-public information about defense-related semiconductor demand, though there's no evidence of wrongdoing.
Since those purchases, Amkor's stock has climbed roughly 60%. That's a pretty nice return for a few months of waiting.
Amkor Rides the Semiconductor Wave
Amkor isn't just benefiting from one senator's buying spree. The company is riding a massive wave in the semiconductor industry, driven by AI-related demand. Analyst Adam Parker recently called semiconductors his "North Star," arguing that the AI buildout is real and not a bubble. Amkor, as a packaging and testing specialist, is well-positioned to benefit as chipmakers ramp up production.
The company's first-quarter results were upbeat, with earnings of 33 cents per share on revenue of $1.69 billion—both beating expectations. For the second quarter, Amkor guided for earnings between 42 and 52 cents per share, well above the previous estimate of 31 cents, and revenue of $1.75 billion to $1.85 billion. Analysts responded by lifting their price targets.
Insider Confidence
It's not just politicians who are bullish on Amkor. Board member Robert R. Morse exercised stock options for 20,000 shares in early April, a transaction worth over $1 million. Insider buying like that often signals confidence in the company's prospects.
MarketDash's stock rankings show that AMKR has strong price trends across short, medium, and long timeframes, with a Growth score in the 91st percentile and a Momentum score in the 98th percentile. That's about as good as it gets.
Mullin did not immediately respond to a request for comment.
