Both have compounded well over 10 years (CAH: +158. 8%, TDOC: -38. 7%), 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: YI is a small-cap quality compounder stock; OPRX is a small-cap high-growth stock; TDOC is a small-cap quality compounder stock; MCK is a mid-cap quality compounder stock; CAH is a mid-cap quality compounder stock. CAH pays a dividend while YI, OPRX, TDOC, MCK do not, making them suitable for different income and tax situations.
