4% yield), MRK (2. 9% yield), AMGN (2. 9% yield), LLY (0. 6% yield) pay a dividend. ERAS does not pay a meaningful dividend and should not be held primarily for income.

71), 0. 6% yield, +1238% 10Y return). Both have compounded well over 10 years (LLY: +1238%, ERAS: -40. 3%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections.

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

In terms of investment character: ERAS is a small-cap quality compounder stock; LLY is a large-cap high-growth stock; MRK is a large-cap deep-value stock; BMY is a mid-cap deep-value stock; AMGN is a mid-cap quality compounder stock. LLY, MRK, BMY, AMGN pay a dividend while ERAS does not, making them suitable for different income and tax situations.
