Highlights

  • End of Fixed Commissions – May 1, 1975, marked the end of mandatory brokerage commission rates.
  • Increased Competition – Brokers could set their own fees, leading to lower costs for investors.
  • Birth of Discount Brokers – The change paved the way for discount brokerage firms and modern trading.

May Day, referring to May 1, 1975, was a pivotal moment in the history of financial markets. On this date, the U.S. Securities and Exchange Commission (SEC) abolished fixed brokerage commission rates, allowing brokers to charge competitive fees instead of a standardized rate. This marked a fundamental shift in the way securities were traded, increasing accessibility and affordability for investors.

Prior to May Day, brokerage firms operated under a fixed-commission structure, which limited competition and kept trading costs high. With deregulation, firms were free to determine their own commission rates, sparking intense competition and the emergence of discount brokerage firms. This development significantly reduced transaction costs, making stock market participation more attractive to a broader range of investors.

The impact of May Day was profound, reshaping the financial industry and setting the stage for innovations in electronic trading and online brokerage platforms. Over time, the move toward lower fees and commission-free trading models has democratized investing, benefiting both retail and institutional investors.

Conclusion

May Day revolutionized the brokerage industry by eliminating fixed commissions, fostering competition, and making investing more accessible. This historic change laid the foundation for the modern trading environment, ultimately empowering investors with lower costs and greater market participation.
