Both have compounded well over 10 years (INSP: +70. 9%, NYXH: -94. 2%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.

These companies operate in different sectors (NYXH (Healthcare) and INSP (Healthcare) and LIVN (Healthcare) and AVAV (Industrials) and NVCR (Healthcare)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: NYXH is a small-cap high-growth stock; INSP is a small-cap deep-value stock; LIVN is a small-cap quality compounder stock; AVAV is a small-cap quality compounder stock; NVCR is a small-cap quality compounder 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.
