24), 1. 2% yield, +375. 2% 10Y return). Caterpillar Inc. (CAT) carries a higher beta of 1. 54 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (LIN: +375. 2%, CAT: +1228%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

These companies operate in different sectors (ARMN (Basic Materials) and LIN (Basic Materials) and CAT (Industrials) and APD (Basic Materials)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

LIN, CAT, APD pay a dividend while ARMN does not, making them suitable for different income and tax situations.
