1% yield), IMOS (1. 9% yield), LYTS (0. 8% yield) pay a dividend. GSIT, ONTO do not pay a meaningful dividend and should not be held primarily for income.

For long-horizon retirement investors, ChipMOS TECHNOLOGIES Inc.

(IMOS) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (1. 9% yield, +301. 1% 10Y return). GSI Technology, Inc. (GSIT) carries a higher beta of 3. 02 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (IMOS: +301. 1%, GSIT: +126. 1%), 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 (GSIT (Technology) and LYTS (Technology) and ACCO (Industrials) and IMOS (Technology) and ONTO (Technology)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

In terms of investment character: GSIT is a small-cap quality compounder stock; LYTS is a small-cap high-growth stock; ACCO is a small-cap deep-value stock; IMOS is a small-cap quality compounder stock; ONTO is a mid-cap quality compounder stock. LYTS, ACCO, IMOS pay a dividend while GSIT, ONTO do not, making them suitable for different income and tax situations.
