Could you provide me with some data that shows that they are losing market share and/or are seeing pricing pressure? It's not evident from their gross profit margins or their revenue.
In a research note, IC Insights said that TSMC is expected to post US$28.57 billion in sales for 2016, up 8 percent from a year earlier. Despite the sales growth, TSMC's market share for 2016 is likely to fall one percentage point from a year earlier, IC Insights added.
The foundry market in general is growing and, even though consolidation in the foundry business is still taking place, TSMC is not the winner. We'll see what happens once foundry competition rises in the 14nm and 10nm space.
But you're right, it's still a bit early to call. It's just what I think is happening.
