What is a cashtag?

A cashtag is a symbol (the "$" sign followed by a stock ticker symbol) used on social media platforms, particularly Twitter, to identify and track discussions and mentions of a specific publicly traded company. It allows users to easily search for and follow conversations related to a particular company's stock. Cashtags are similar to hashtags, which are used to categorize and organize content on social media. They are often used by investors, traders, and financial professionals to stay informed about market trends and news related to specific companies.
