By the Top Tier Newswire AI Desk · July 29, 2026 at 5:29 AM ET · reviewed against 6 wire stories

AMKOR TECHNOLOGY INC (AMKR) is drawing unusual attention today. Our newswire has captured 6 stories on AMKR across 4 sources in the last 36 hours, with AI sentiment reading mixed (avg 57/100).

Why AMKR stock is down today

Amkor Technology Inc (AMKR) fell 24.74% to $45.69 in the session, marking one of the largest declines in recent weeks. The sharp drop followed the company's Q2 earnings report, which included a record revenue of $1.9 billion but was accompanied by weaker-than-expected guidance for the next quarter. Analysts and investors focused on the cautious outlook, which overshadowed the strong performance in AI-driven growth and led to immediate selling pressure.

What Happened

Amkor reported its highest quarterly revenue ever, up 26% year-over-year to $1.9 billion with earnings per share of $0.70, exceeding expectations. However, the company’s Q3 revenue guidance of $1.95 billion to $2.05 billion failed to meet investor expectations, prompting a sharp selloff. The stock closed down for a fourth consecutive session, with Barron's reporting a 23% drop. B. Riley highlighted near-term challenges, including program delays and AI sentiment pressure, as potential sources of continued volatility. Morgan Stanley recently raised its price target to $70 but maintained an equal-weight rating, suggesting a neutral stance despite the recent decline.

What The Data Shows

The stock has fallen 26.7% over the last eight sessions, from $62.94 to $46.14. Insiders have sold $6.2 million worth of shares in the past 90 days, with no insider purchases recorded. Recent transactions include sales by EVP Mark Rogers and CFO Megan Faust. The stock is now trading below its 200-day moving average for the first time in nearly a year. With a beta of 2.21, AMKR has been more volatile than the broader market. The stock’s 52-week range is $20.86 to $96.68, and its P/E ratio of 34.9 suggests it is trading at a premium relative to earnings.

What To Watch

The company’s next earnings report will be a key event to monitor. Until then, investors should watch for shifts in coverage and analyst sentiment, particularly as AI sector dynamics and supply chain developments could influence Amkor’s performance.
