Semiconductor sales volumes inevitably vary depending on a company's business environment and interests.
Depending on the type of semiconductor, the variables that determine the business environment or stock price movement of a semiconductor company may vary.
If you understand the characteristics of semiconductor companies, you will be able to develop various cycle investment strategies.

The PC industry is already considered to have reached its peak growth in the 2000s.
However, as PC performance advances day by day, the performance of semiconductor chips is also steadily improving.
Therefore, let's focus on technological change rather than industrial growth potential.
It's also worth noting what new transistor structures and manufacturing processes Intel, AMD, and TSMC are developing.

In addition to Anapass, MagnaChip has been aggressively expanding its DDI business, and Wonik Group is expected to enter the DDI market starting in 2023, signaling fierce competition. The DDI market is expected to evolve toward rapid development of DDIs optimized for new displays to maintain the lead over rapidly catching up Chinese companies and avoid losing market share to domestic competitors.

The smartphone market expanded from focusing on high-end products to focusing on mid- to low-end products, and as the number of smartphones increased, the number of related semiconductors also increased.
Some companies, such as DB HiTek, benefited from this process.
These benefits could be repeated in the future as wearable devices that complement smartphones increase in number.

As non-memory semiconductors become more important, the role of memory semiconductors also grows. Just as the CPU, GPU, and FPGA markets are monopolized by Nvidia, Intel, and AMD, the memory semiconductor market is dominated by Samsung Electronics, SK Hynix, and US memory semiconductor manufacturer Micron.
These companies benefit significantly.

The automotive semiconductor industry must consider not only the companies that manufacture automotive semiconductors, but also the changes in vehicle functionality.
For example, in the past, even implementing the function of folding and unfolding side mirrors while parking required a dedicated processor. While the PC, smartphone, and server industries often see single companies developing semiconductors across these industries, the automotive semiconductor industry is uniquely characterized by a significant number of companies focused solely on automotive semiconductors.
This is why we need to pay more attention to changes in vehicle trends.

One of the most important trends in the semiconductor industry today is the vertical integration of multiple chips, centered around high-performance chips.
Efforts to address this will continue in the coming years, leading to rapid technological change.
Given the massive trend in the semiconductor industry, long-term investment may seem advantageous. However, in principle, the more rapidly technological change occurs in an area, the more advantageous it is to make mid-term investments rather than simply holding onto the stocks of related companies for the long term.
