Another View on Lumentum Holdings Valuation

The earlier work based on fair value estimates presents Lumentum Holdings as heavily undervalued. The picture changes when you look at the price to sales ratio. Lumentum trades on a P/S of 25.7x versus 12.8x for peers and 2.5x for the wider US Communications industry, while the fair ratio is 22.4x. That leaves the stock priced well above both the sector and the level the market could move toward if sentiment cools, which increases the risk of sharp multiple compression if expectations slip even slightly.
