(UFPI) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 92), 1. 7% yield, +230. 6% 10Y return).

Both have compounded well over 10 years (UFPI: +230. 6%, ASPN: +13. 6%), 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 (ASPN (Industrials) and KALU (Basic Materials) and UFPI (Basic Materials) and MTRN (Basic Materials) and OC (Industrials)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.
