People are very excited about the future of AI and how it will change our lives. Because of this, many people want to buy shares (pieces) of Taiwan Semi, making its price go up a lot.

Taiwan Semi is building new factories all around the world to make more AI chips for big tech companies like Amazon, Microsoft, and Apple, who also believe in the power of AI. Read from source...

1. The title of the article is misleading and sensationalized, as it implies that Nvidia Supplier Taiwan Semi's global expansion and AI revenue growth are in focus despite some negative signals or challenges. However, the article does not provide any concrete evidence or data to support this claim, nor does it explain what these overbought signals are or how they affect the company's performance.
2. The article uses vague and ambiguous language throughout, such as "signs", "speculation", "concern", "questioning" without providing any clear definitions, sources, or references to back up their claims. This makes the article seem unprofessional and unreliable.
