Large trades were already exempt from fully fixed commissions before May 1, 1975. The SEC had phased in negotiated rates for big orders years earlier, so a 100,000-share trade did not necessarily pay a completely fixed commission right up to May Day.

Full reasoning

This overstates how universal fixed commissions still were by May 1, 1975.

The historical record shows that large orders had already been partially or fully "unfixed" before May Day:

  • The SEC Historical Society says the SEC had already ended fixed commissions on transactions above $500,000 in 1972.
  • Its broader market-structure history says the SEC's phased approach began in 1971 for orders above $500,000 and continued in 1972 for orders above $300,000.
  • Contemporary legal summaries likewise note that the SEC had already allowed a high-dollar breakpoint below which fixed rates could remain, meaning very large institutional trades were not all paying a single non-negotiable schedule until May 1, 1975.

So the article's claim is too absolute. Small investors generally still faced fixed-rate schedules, but very large trades were already subject to negotiated commissions before May Day.
