What Happened:

Shares of semiconductor packaging and testing company Amkor Technology (NASDAQ:AMKR) jumped 5.9% in the morning session after Needham analyst initiated coverage on the stock and assigned a $40 price target. The price target implied a potential 20% upside from where shares traded when the coverage was initiated. The analyst cited some reasons for the bullish outlook, adding, "Ultimately, we believe the stock represents a strong buying opportunity as it lacks deserved premiums for the company's limited geopolitical risk and its exposure to AI." After the initial pop the shares cooled down to $32.72, up 4.4% from previous close.

What is the market telling us:

Amkor's shares are very volatile and over the last year have had 12 moves greater than 5%. In context of that, today's move is indicating the market considers this news meaningful but not something that would fundamentally change its perception of the business. 

The biggest move we wrote about over the last year was 7 months ago, when the stock dropped 9.3% on the news that the company announced the launch of a secondary offering of 10 million shares of common stock by selling stockholders ( 915 Investments, LP). Note that the company's total base of shares is roughly 250 million. 915 Investments is an investment vehicle for members of the family of James J. Kim, the founder and executive chairman of the board of Amkor, and Susan Y. Kim, the executive vice chairman of the board. Following the sale, members of the Kim family and their affiliates will continue to own a majority of Amkor's shares. 

A secondary offering is when existing shareholders sell their shares to new investors. In the case of Amkor, the secondary offering is not being done by the company but by selling stockholders. This means that Amkor will not receive any proceeds from the sale. However, the offering could still have a negative impact on the company's stock price, as it could signal that existing shareholders believe the stock is overpriced or are not confident in the company's future prospects. This is not always the case, just a possibility.

Amkor is up 2.2% since the beginning of the year, but at $32.72 per share it is still trading 9.3% below its 52-week high of $36.09 from March 2024. Investors who bought $1,000 worth of Amkor's shares 5 years ago would now be looking at an investment worth $3,684.
