(TER) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (+1833% 10Y return). Applied Materials, Inc.

Both have compounded well over 10 years (TER: +1833%, AMAT: +21. 4%), 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: LRCX is a large-cap high-growth stock; TER is a mid-cap quality compounder stock; AMAT is a large-cap quality compounder stock; KLAC is a large-cap high-growth stock; COHU is a small-cap quality compounder stock.
