Amkor Technology's 15min chart shows RSI Overbought and KDJ Death Cross signals.

Based on Amkor Technology's 15-minute chart, we observe a number of indicators that suggest the stock is experiencing an overbought condition, as evidenced by a reading on the Relative Strength Index (RSI) that exceeds its upper threshold. Furthermore, the Keltner's Directional Indicator (KDJ) has recently crossed below its signal line, a phenomenon known as a "death cross," which is a bearish signal that indicates a shift in momentum towards the downside. This suggests that the stock price has risen too rapidly and is now unsupported by fundamental analysis, with a high likelihood of further decreases in the near term.
