Both have compounded well over 10 years (IDCC: +404. 7%, MARA: -63. 7%), 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 (VHC (Technology) and ACTG (Industrials) and MARA (Financial Services) and IDCC (Technology) and XOMA (Healthcare)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.
