Insight and Analysis has a detailed analysis of Cypress Semiconductor here. Here is an excerpt:

“With $1.9 billion revenues, Cypress Semiconductor ranked number 22 of all the companies in the U.S. semiconductor industry.There were a total of 70 public companies in the U.S. semiconductor industry that had revenues greater than $50 million during 2017.”


Here is a recent Seeking Alpha assessment of the company by tech analyst David Barbalas:

“Cypress Semiconductors (NASDAQ: CY) is a leading American semiconductor company focusing on the development and manufacturing of memory modules, micro-controllers, all-in-one chip solutions and integrated circuits. Started by several engineers from AMD in 1982, it has strong roots in developing memory and integrated chip solutions.

“The prospects for this corporation lie primarily in the developments in the Internet of Things (IoT) products and wearable technologies. By utilizing the synergistic effect of their wide range of memory products, we can expect CY to further leverage their holdings in IoT into the near future. Aside from their IoT products, Cypress also maintains a presence in touchscreen controllers. While Apple and Samsung have developed in-house products for their applications in mobile devices, there are still applications for infotainment systems and touchscreen interfaces for instruments and electronic devices.

“I believe that Cypress Semiconductors has the potential to be a good pick for those who want another good pick in the semiconductor industry. While Micron (NASDAQ: MU) has been an outstanding stock pick in this sector in the past few months, I believe that Cypress Semiconductors will likely outpace industry stalwart, Intel (NASDAQ: INTC) in the near future and be a good choice for those investors seeking short-term gains and long-term growth.”
