In this comparison, NNN (5.

3% yield), O (5. 2% yield), PDM (2. 9% yield), VNO (2. 3% yield) pay a dividend. SPG does not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, Realty Income Corporation (O) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0.

09), 5. 2% yield). Both have compounded well over 10 years (O: +45. 1%, VNO: -34. 5%), 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.

Both stocks operate in the Real Estate sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: PDM is a small-cap quality compounder stock; O is a mid-cap income-oriented stock; NNN is a small-cap income-oriented stock; VNO is a small-cap deep-value stock; SPG is a mid-cap deep-value stock. PDM, O, NNN, VNO pay a dividend while SPG does not, making them suitable for different income and tax situations. 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.
