The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Sonoco Products Company wins at 0. 62x versus Sealed Air Corporation's 9. 73x — a PEG below 1. 0 traditionally signals the market is underpricing earnings growth.

1%, compared to -33. 2% for Graphic Packaging Holding Company (GPK). Over 10 years, the gap is even starker: AMCR returned +417. 0% versus SEE's +4. 4%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

Amcor plc (AMCR) offers the highest yield at 6. 6%, versus 1. 9% for Sealed Air Corporation (SEE).

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

32), 1. 9% yield). Both have compounded well over 10 years (SEE: +4. 4%, GPK: +12. 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.
