Why Is AMKOR TECHNOLOGY INC (AMKR) Stock Down Today?

Why AMKR stock is down today

Amkor Technology Inc (AMKR) fell 24.72% to $45.70 in a volatile session marked by a sharp intraday decline and elevated trading volume. The stock opened with a 7.7% gap down from the previous close and continued to fall throughout the session as investors reacted to the company's Q3 revenue guidance, which fell below expectations despite record Q2 results.

What Happened

The stock's sharp decline came after Amkor reported Q2 2026 results that included a revenue beat and strong margins, but its Q3 revenue guidance failed to meet Wall Street expectations. The company's guidance for the next quarter was seen as a key factor in the sell-off, as it signaled potential near-term headwinds. Additionally, Amkor's stock has been under pressure for four consecutive sessions, with its recent performance reflecting ongoing investor skepticism about the sustainability of its growth. The stock's drop also occurred amid broader market uncertainty, with S&P 500 futures trading flat in premarket hours and other technology stocks like Corning also lagging.

What The Data Shows

The intraday session showed a steep decline, with the stock falling from an opening price of $56.03 to a low of $45.22. The session volume of 8.8 million shares is 1.8 times the 3-month daily average, indicating heightened investor activity. Over the last eight sessions, AMKR has fallen 26.7% from $62.94 to $46.14. Recent insider transactions also show selling pressure, with 7 sales totaling $6.2 million reported in the last 90 days. The stock's fundamentals include a P/E ratio of 34.9 and a net margin of 6.2%, but its beta of 2.21 indicates it is more volatile than the broader market.

What To Watch

The next key event for Amkor investors will be the company's upcoming earnings report, which will provide further insight into its performance and guidance. Investors should also monitor coverage breadth and any changes in analyst sentiment, particularly given the recent lowering of the price target by B. Riley Securities to $65.
