there is no long term sustainable competitive advantage for any of them. And not for SWKS . If you think long term means at least a decade. But the stock market does not think a decade ahead.
Linear Technology (LLTC) seemed to have a strong competitive edge in 2000 when it hit $55 or so. Despite decent business it is lower now 16 years later. But the P/E of SWKS is not sky high and I suspect it’s advantage will last a few years.
I don’t follow LLTC, but a quick look at their financial demonstrates that they do indeed have a long term competitive advantage. For how else could they maintain such impressive ROE, ROA, and net margins year after year after year? Where are all the capitalist-loving competitors entering the business, dragging margins and returns down toward the cost of capital??
Even in the matter of growth, they’ve grown free cash flow per share at about 5% per year over the past decade. The problem isn’t with LLTC as a business, nor with the sustainability of their competitive advantage, but rather with the absurd prices people were paying for a fractional share of the business in 2000. The best business in the world can be a failure if you pay a stupid price. On the flip side, given that Skyworks has a current earnings yield of 10%, if it grows 5% CAGR for the next decade (mirroring LLTC), it will be a phenomenal investment. And odds are enormously high that the growth will be higher, given that they’re in a much higher growth industry than LLTC was a decade ago…as they say “mobile is eating the world”, and Skyworks (and the couple other businesses that can do what they do) are empowering that.
So, if anything, the persistence of LLTC’s moat in it’s particular analog business strengthens the case for the likes of SWKS and QRVO.
