8% yield) pays a dividend. INVA does not pay a meaningful dividend and should not be held primarily for income.

67), 1. 8% yield, +290. 3% 10Y return). Both have compounded well over 10 years (AZN: +290. 3%, INVA: +90. 5%), 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: INVA is a small-cap high-growth stock; AZN is a large-cap quality compounder stock. AZN pays a dividend while INVA does not, making them suitable for different income and tax situations. These fundamental differences mean investors should not choose between them on a single metric — the "better stock" depends entirely on which of these characteristics aligns with your investment strategy.
