For long-horizon retirement investors, AbbVie Inc.

(ABBV) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β 0. 14), 2. 9% yield, +362. 2% 10Y return). Inventiva S. A. (IVA) carries a higher beta of 1. 59 — meaning larger drawdowns in market downturns, which matters significantly when you cannot wait years for a recovery. Both have compounded well over 10 years (ABBV: +362. 2%, IVA: -71. 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.

In terms of investment character: IVA is a small-cap quality compounder stock; ABBV is a large-cap quality compounder stock; MRK is a large-cap deep-value stock; SNY is a mid-cap income-oriented stock; JNJ is a large-cap quality compounder stock. ABBV, MRK, SNY, JNJ pay a dividend while IVA does not, making them suitable for different income and tax situations.
