Head-to-Head Comparison
AMKR and TSEM both thrive on semiconductor tailwinds but differ in business models: AMKR emphasizes OSAT for final chip assembly, while TSEM focuses on foundry fabrication of custom ICs. Growth drivers align on AI demand—AMKR via advanced packaging, TSEM through RF and photonics—yet TSEM shows stronger multi-year momentum. Recent relative performance favors TSEM's lower volatility (beta 0.85 vs. 2.31) and leaner balance sheet (less debt), but AMKR counters with higher revenue ($7.07B TTM vs. $1.57B) and cheaper valuation (P/E 44 vs. 109). Risk factors include cyclical downturns and supply chain dependencies for both, with TSEM facing litigation headwinds. Market sentiment tilts bullish on foundry scalability over packaging amid capacity constraints.
Tickeron AI Verdict
Tickeron’s AI currently favors TSEM due to superior trend consistency, explosive multi-year returns, lower beta for stability, and positioning in high-growth foundry niches like AI photonics. While AMKR offers value via earnings beats and scale, TSEM's relative momentum and catalysts suggest higher probability of outperformance in the near term, particularly if sector demand persists.

To compare these two companies we present long-term analysis, their fundamental ratings and make comparative short-term technical analysis which are presented below. The conclusion is AMKR is a Hold and TSEM is a Hold.
Long-Term Analysis
It is best to consider a long-term outlook for a ticker by using Fundamental Analysis (FA) ratings. The rating of 1 to 100, where 1 is best and 100 is worst, is divided into thirds. The first third (a green rating of 1-33) indicates that the ticker is undervalued; the second third (a grey number between 34 and 66) means that the ticker is valued fairly; and the last third (red number of 67 to 100) reflects that the ticker is undervalued. We use an FA Score to show how many ratings show the ticker to be undervalued (green) or overvalued (red).
AMKR’s FA Score shows that 2 FA rating(s) are green whileTSEM’s FA Score has 2 green FA rating(s).
- AMKR’s FA Score: 2 green, 3 red.
- TSEM’s FA Score: 2 green, 3 red.
Short-Term Analysis
It is best to consider a short-term outlook for a ticker by using Technical Analysis (TA) indicators. We use Odds of Success as the percentage of outcomes which confirm successful trade signals in the past.
If the Odds of Success (the likelihood of the continuation of a trend) for each indicator are greater than 50%, then the generated signal is confirmed. A green percentage from 90% to 51% indicates that the ticker is in a bullish trend. A red percentage from 90% - 51% indicates that the ticker is in a bearish trend. All grey percentages are below 50% and are considered not to confirm the trend signal.
AMKR’s TA Score shows that 3 TA indicator(s) are bullish while TSEM’s TA Score has 4 bullish TA indicator(s).
- AMKR’s TA Score: 3 bullish, 5 bearish.
- TSEM’s TA Score: 4 bullish, 4 bearish.
