Stock Ticker Lookup is a convenient way to view information about a highlighted stock ticker on a webpage.

This handy extension for Chrome is built with ease of use in mind. Just highlight the ticker, then click on the extension to view key details like the ticker’s last traded price and current volume.

The extension works by fetching information from the Alpha Vantage API, which is a free, real-time source for data. The API rate limits are meant to keep your rate of data usage in check and prevent abuse, so it's not intended for use by heavy data users.
