The world is being “digitized,” and besides software, semiconductors are the "nuts and bolts" making it all happen (in datacenters, on devices, in the cloud and just about everywhere else too, considering the expansive "Internet of Things" ("IoT")). In this report, we share data on 40+ top semiconductor stocks, ranked by net profit margins (a particularly important metric in the currently challenging macroeconomic environment). We have a special focus on Monolithic Power Systems (MPWR) an "offense-and-defense" chip stock, including a review of its business, financials, valuation and risks. We conclude with our strong opinion on investing in semiconductors in general, and Monolithic Power in particular.
