TSMC has always been my bellwether and for 2019 I think we need to pay careful attention. Bad economic news has been spreading inside the fabless semiconductor ecosystem (tool and IP budgets have been tightening) but I think it is a bit premature. Let’s take a look at the TSMC 2018 Q4 earnings call and talk more about it in the comments section:
 
- Q1 of $7.3B to $7.4B, down 14%
 - TSMC expects 2019 revenue to grow 1% to 3% compared to 6.5% in 2018
 - TSMC cites inventory congestion
 - TSMC expects weak demand until 2H19
