3x versus Packaging Corporation of America at 26. 2x. On forward P/E, Sonoco Products Company is actually cheaper at 8. 9x — notably different from the trailing picture, reflecting expected earnings growth. 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 -18. 8% for Sealed Air Corporation (SEE). 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.

Higher growth typically commands a higher valuation multiple — check whether the premium P/E or P/S is justified by the growth rate using the PEG ratio.

By this metric, Sonoco Products Company (SON) is the more undervalued stock at a PEG of 0. 62x versus Sealed Air Corporation's 9. 73x.

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.

31), 1. 9% yield). Both have compounded well over 10 years (SEE: +4. 4%, SLGN: +80. 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.
