5% yield), ZYXI (0. 5% yield) pay a dividend. STIM, ELMD, NVCR do not pay a meaningful dividend and should not be held primarily for income.

25), 2. 5% yield, +173. 7% 10Y return). NovoCure Limited (NVCR) carries a higher beta of 2. 20 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (ABT: +173. 7%, NVCR: +30. 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.

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