(RCAT) carries a higher beta of 3. 31 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (UMAC: +345. 5%, RCAT: -97. 8%), 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 (PRZO (Industrials) and UMAC (Financial Services) and RCAT (Technology) and JOBY (Industrials)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

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.
