The tickers These are alphanumeric codes that uniquely identify each stock on the stock market. But how did this practice originate?
The beginnings:
- Manual communication: In the early days of stock exchanges, information about stock prices was communicated by shouting or using blackboards. It was a chaotic and inefficient system, especially as the number of listed companies began to grow.
- The teletype machine: In the mid-19th century, the teletypewriter was introduced, an electromechanical device that allowed messages to be transmitted over long distances. This innovation revolutionized stock market communication, allowing stock prices to be transmitted more quickly and accurately.
The birth of tickers:
- Need for abbreviations: With the increasing number of publicly traded companies, a more concise way to identify each stock became necessary. Thus, tickers, which are abbreviations of the company's name, emerged.
- The characteristic sound: Early teletype machines produced a distinctive sound when printing characters, similar to the ticking of a clock. This is where the term "ticker" comes from.
- Standardization: Over time, standards for assigning tickers were established, ensuring that each stock had a unique and recognizable code.
Evolution of tickers:
- From teletype machines to screens: With the advancement of technology, ticker machines were replaced by electronic screens that displayed stock prices in real time. However, tickers remained the standard way of identifying securities.
- The digital age: Today, tickers are used in online trading platforms, mobile applications, and financial information systems. Despite technological advances, the ticker concept remains fundamental to stock market trading.
Why are tickers important?
- Unique identification: Each ticker is a unique identifier that distinguishes one stock from another.
- Efficiency: Tickers streamline stock buying and selling operations.
- Condensed information: By knowing a company's ticker, you can quickly access relevant information about its stock, news, and analysis.
In short, tickers emerged as a practical necessity to efficiently identify stocks in an ever-growing stock market. From their origins as abbreviations transmitted by teletype machines, tickers have become an essential tool for investors worldwide.
