Evaluation from another angle

The main story claims that STMicroelectronics’ fair value is overvalued by 58% at €27.52. However, the current P/S of 3.6x represents considerable value compared to the European semiconductor average of 4.7x, the average of peers of 4.1x, and the appropriate ratio of 6.1x where the market is likely to be headed. This begs the question of whether sentiment is ahead of the curve or whether multiples have yet to catch up.
