In which fields are the company’s products mainly applied (consumer electronics, automotive, industrial, data centers, AI, new energy, etc.)? How is the demand in these downstream fields?

4. Pay Attention to Industry Trends and Policies:

Domestic substitution, breakthroughs in advanced processes, demand for AI chips, electrification and intelligence of automobiles, and third-generation semiconductors (SiC, GaN) are all important trends. National policy support is also a key factor.

5. Research Financial Conditions:

Revenue growth, profitability (gross margin, net margin), R&D investment ratio, cash flow status, etc., are all very important. The semiconductor industry requires heavy R&D investment.

6. Assess Valuation Levels:

Based on the company’s growth potential, profitability, and industry position, determine whether the current stock price valuation (PE, PEG, PS, etc.) is reasonable. Semiconductor stock valuations tend to fluctuate significantly.

7. Pay Attention to Management and Corporate Governance: Excellent management is key to the long-term development of the company.
