The PEG ratio (P/E divided by earnings growth rate) is the most growth-adjusted single valuation metric: Digi International Inc. wins at 0. 87x versus LSI Industries Inc.

2%, compared to -9. 3% for Calix, Inc. (CALX). Over 10 years, the gap is even starker: CIEN returned +32. 3% versus LYTS's +108. 5%. Past returns do not guarantee future results, and the stock with the higher historical return may already have its best growth priced in.

(CALX) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 99), +513. 0% 10Y return). Ciena Corporation (CIEN) carries a higher beta of 2. 46 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (CALX: +513. 0%, CIEN: +32. 3%), 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.
