Amkor Technology's 15min chart shows Bollinger Bands narrowing, KDJ death cross.

The 15-minute chart for Amkor Technology has recently exhibited Bollinger Bands Narrowing, accompanied by a KDJ Death Cross at 08/18/2025 15:00. This suggests a diminution in the magnitude of stock price fluctuations, as well as a shift in momentum towards the downside, potentially leading to further decreases in the stock's value.

Amkor Technology's 15-minute chart has recently exhibited significant technical indicators suggesting a potential downward trend in its stock price. On August 18, 2025, at 15:00, the Bollinger Bands narrowed, indicating a decrease in the magnitude of stock price fluctuations [1]. Concurrently, the Keltner Directional Indicator (KDJ) crossed below its signal line, a development known as the KDJ Death Cross, indicating a shift in momentum towards the downside [1].

These indicators, along with the previous MACD and KDJ Death Cross signals on August 8, 2025 [2], suggest that Amkor Technology's stock price may continue to decline. The MACD indicator, a trend-following momentum oscillator, shows the relationship between two moving averages of a security's price, and its recent crossing below the signal line reinforces the bearish trend.

The company's insiders have also shown confidence in the stock, with significant purchases reported. Kim David D, a member of the 10% owner group, acquired 441,589 shares on August 1, 2025, at $21.85 per share, totaling $9.6 million [3]. This purchase comes as the stock has shown significant volatility, declining 11.6% in the past week. Despite this, the stock has shown resilience, with recent earnings beating expectations and analysts maintaining a mixed outlook.

Amkor Technology, an OSAT (outsourced semiconductor assembly and test) service provider, has seen positive revenue growth of 3.42% over the past three months, but its gross margin remains low at 12.04%, indicating potential cost efficiency issues. The company's P/E ratio of 18.17 and EV/EBITDA ratio of 4.82 suggest that the stock may be undervalued, making it an attractive option for value-focused investors [4].

On a positive note, Amkor Technology declared a $0.0827/share quarterly dividend, in line with previous declarations [2]. The forward yield is 1.33%, payable on September 23, for shareholders of record on September 3, with an ex-div date of September 3.

Investors should monitor these technical indicators and insider transactions closely, as they can provide valuable insights into the stock's future performance. However, it is essential to consider other factors, such as the company's financial health and overall market conditions, before making investment decisions.
