Both have compounded well over 10 years (SYNX: -67. 0%, SONO: -24. 4%), 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 (SYNX (Technology) and KOSS (Technology) and SONO (Technology) and SGRP (Industrials)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: SYNX is a small-cap high-growth stock; KOSS is a small-cap quality compounder stock; SONO is a small-cap quality compounder stock; SGRP 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.
