While the tech industry watches Taiwan Semiconductor Manufacturing Co. amid a global chip shortage, one of its neighbors has been a far better bet for investors.

United Microelectronics Corp. is a distant second to TSMC in the market for pure custom-manufacturing of chips in almost every measure: technology, capacity, revenue, margins. But in the metric that counts the most — share returns — the company has taken the crown. Its Taipei-listed shares have jumped more than 300% over the past year, double that of its rival. Both have done even better with their New York-traded depositary receipts.
