Now what

The chipmaker saw strong orders for high-margin chips that go into such tech as 5G smartphones and high-performance computing systems of the enterprise-class variety. The richer product mix explains how TSMC generated a positive bottom-line surprise despite its slight miss on the revenue line. These trends should continue in the next reporting period.

The automotive computing sector is also staging a comeback in early 2021, and management promised to prioritize automotive chip orders in the near term, supporting the industry's recovery process.

"In TSMC, this is our top priority and we are working closely with our automotive customer to resolve the capacity support issue," CEO C.C. Wei said on the earnings call.

Investors were quick to embrace TSMC's solid results and promising outlook. The stock set a new all-time high Thursday, having gained 98% over the last 52 weeks.
