What is Stock Peek?
Stock Peek is a free Windows and Mac desktop stock widget designed for checking a watchlist without switching away from your current work.
Move the mouse to the left or right screen edge and Stock Peek reveals US, Korean, Japanese, Indian and Saudi watchlist quotes, three-month price charts, and portfolio profit and loss.
Core features
- The panel appears at the screen edge and automatically hides when you move the cursor away.
- Search US stocks and ETFs from major exchanges, Korean stocks from KOSPI and KOSDAQ, Japanese stocks from the Tokyo Stock Exchange, Indian stocks from the NSE, and Saudi stocks from Tadawul.
- Enter shares and average purchase price to view current portfolio profit and loss.
- View a compact chart based on the last three months of daily prices.
- Place the panel on the left or right edge of any connected monitor.
- Keep the app in the system tray (menu bar on Mac) and optionally launch it at login.
How to install and use it
- Download the installer: Get the latest installer from GitHub Releases and run it: `.exe` for Windows, `.dmg` for Mac.
- Add your watchlist: Search by company name or ticker. Optionally enter shares and average purchase price.
- Move to the screen edge: Move the cursor to the configured edge. The panel appears and hides when you move away.
Because the independent app is not code-signed, Windows SmartScreen may display a warning. Choose “More info” and then “Run anyway” to continue. On a Mac (macOS 12 or later), open the downloaded file and move the app to Applications. It isn’t notarized by Apple, so if the first launch is blocked, go to System Settings → Privacy & Security and click “Open Anyway”.
Quote sources and refresh timing
Korean quotes come from Naver Finance and US, Japanese, Indian and Saudi quotes from Yahoo Finance public data; Japanese quotes are delayed 20 minutes and Saudi quotes 15 minutes. The app checks every 3 seconds during market hours and every 60 seconds after close. Exchange and provider policies may cause delays.
Privacy and local storage
Stock Peek does not connect to a brokerage account or place orders. Watchlist items, shares, average purchase prices, language, and panel position are stored on the user's PC.
See the privacy and data handling page for details.
