Excelente análise, celtiberian.
Uma coisa interessante dessas empresas dos EUA é que elas são obrigadas a elencar os riscos que antecipam para seus negócios nos relatórios anuais. A leitura desses riscos dá uma visão muito boa dos problemas que podem impactar os lucros da empresa.
No relatório anual do ano passado dessa empresa aqui (

"The electronics industries and semiconductor market are cyclical and subject to significant and often rapid increases and decreases in product demand. Our semiconductor foundry business is affected by market conditions in such highly cyclical electronics and semiconductor industries."
"Over the years, our customer profile and the nature of our customers’ business have changed dramatically. While we generate revenue from hundreds of customers worldwide, our ten largest customers in 2014, 2015, and 2016 accounted for approximately 63%, 63% and 69% of our net revenue in the respective year. Our largest customer in 2014, 2015, and 2016 accounted for 21%, 16% and 17% of our net revenue in the respective year. Our second largest customer in 2014, 2015, and 2016 accounted for 9%, 16% and 11% of our net revenue in the respective year."
"The markets for our foundry services are highly competitive. We compete with other foundry service providers, as well as integrated device manufacturers that devote a significant portion of their manufacturing capacity to foundry operations. Some of these companies may have access to more advanced technologies and greater financial and other resources than us, such as the possibility of receiving direct or indirect government
bailout/economic stimulus funds or other incentives that may be unavailable to us. For example, China companies are expected to be the key
drivers of new semiconductor fab development and fab equipment spending through 2020. In 2016 alone, it was reported that over twenty new semiconductor fab projects have been announced or being developed within China due to various incentives provided by China government."
