9% yield), MCK (0. 4% yield) pay a dividend. GDS, VNET, AMZN do not pay a meaningful dividend and should not be held primarily for income.

(COR) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 13), 0. 9% yield, +269. 7% 10Y return). VNET Group, Inc. (VNET) carries a higher beta of 2. 70 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (COR: +269. 7%, VNET: -36. 8%), 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 (GDS (Technology) and COR (Healthcare) and MCK (Healthcare) and VNET (Technology) and AMZN (Consumer Cyclical)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.
