Growth + cash flow

Century Aluminum Company is a rare growth stock that's already generating positive cash flow while growing at 20%. The Winston Score doesn't fully credit this transition from "burner" to "earner."

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
