0% yield), IMOS (1. 9% yield) pay a dividend. GFS, INTC do not pay a meaningful dividend and should not be held primarily for income.

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

90), 3. 0% yield, +895. 3% 10Y return). GLOBALFOUNDRIES Inc. (GFS) carries a higher beta of 1. 85 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (UMC: +895. 3%, GFS: +52. 9%), 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 Technology sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.

In terms of investment character: GFS is a mid-cap quality compounder stock; UMC is a mid-cap income-oriented stock; IMOS is a small-cap quality compounder stock; INTC is a large-cap quality compounder stock.

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.
