06), 2. 2% yield, +132. 3% 10Y return). AbCellera Biologics Inc.

Both have compounded well over 10 years (JNJ: +132. 3%, ABCL: -91. 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.

Both stocks operate in the Healthcare sector, making this a peer-level intra-sector comparison — the same macro tailwinds and headwinds will affect both.
