In terms of investment character: NEOV is a small-cap high-growth stock; TSLA is a mega-cap quality compounder stock; ENPH is a small-cap quality compounder stock; SEDG is a small-cap high-growth stock. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
