Many “free” stock apps for macOS are free to download and then ask for a subscription. These are the ones that are free for real, plus one whose free tier is usable, with exactly what you get without paying.
Facts checked on from each app's US Mac App Store listing.

If you only check prices now and then, Apple's Stocks app is already installed. If you want them always visible, you need a menu bar app: StockDock, Stox and Stock Ticker cost nothing and have no paid tier listed. Uptick's free version is a good fit only for 3 symbols or fewer; positions and alerts are Pro.
