What Happened?

Shares of semiconductor packaging and testing company Amkor Technology (NASDAQ: AMKR) jumped 2.9% in the afternoon session after B. Riley raised its price target on the stock and investors anticipated the company's upcoming earnings report, which saw positive estimate revisions. 

The analyst firm increased its price target on Amkor to $29 from $24, while keeping a Neutral rating. The positive sentiment came just before the company was scheduled to release its third-quarter 2025 earnings results. Fuelling the optimism, analysts had already lifted their financial forecasts for the company. Over the previous 90 days, full-year revenue estimates for 2025 were increased from $6.22 billion to $6.60 billion. In a similar vein, earnings per share estimates for the full year 2025 also rose from $1.09 to $1.13.

After the initial pop the shares cooled down to $32.90, up 2.9% from previous close.

What Is The Market Telling Us

Amkor’s shares are quite volatile and have had 19 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 11 days ago when the stock gained 7.3% on the news that investor fears eased as President Trump softened his tone regarding trade relations with China. Following a sharp selloff late last week fueled by threats of an additional 100% tariff on Chinese goods, the president's more conciliatory weekend message that "it will all be fine" sparked a broad market rally. The semiconductor sector, which is particularly sensitive to international trade policies due to its global supply chains, was among the biggest beneficiaries of the improved sentiment. Chipmakers had posted significant declines during the previous week amid escalating tariff concerns. The reversal in tone helped these stocks recover a substantial portion of their recent losses as investors bought back into the sector, relieved that trade tensions might not escalate further.

Amkor is up 26.5% since the beginning of the year, and at $32.90 per share, has set a new 52-week high. Investors who bought $1,000 worth of Amkor’s shares 5 years ago would now be looking at an investment worth $2,457.
