Does Alpha and Omega Semiconductor have an economic moat?
Not clearly

The numbers behind it
Return on invested capital, average of recent years9.4%
Return on invested capital, latest year-4.8%
Gross margin23.1%Share of each sale left after production costs
Net margin-13.9%
How we decide
A moat shows up in the numbers as high returns that last. We call it likely when the average return on invested capital over recent years is at least 15% and the gross margin at least 40%, and possible from 10%. The numbers can't show where a moat comes from (brand, network, patents), only that one seems to exist.
