Technology brings together some of the world's most profitable businesses —software, semiconductors, internet— but also the most demanding valuations. High margins, sustained growth and a hard-to-copy moat matter most here; the investor's challenge is not to overpay for future growth.
This ranking sorts by fundamental quality, not by whether a stock is cheap or expensive: an excellent company can be expensive. To find the fair price, enter its quote in the analyzer. The scores recompute on their own with each new SEC filing.
