Key insights

  • The SEC is proposing to scrap the 'best price' rules from 2005, which mandated trading platforms to ensure retail investors receive the best possible prices. Critics, like BetterMarkets, argue this will harm retail investors. The potential removal of these protections could lead to less favorable execution prices for individual traders, potentially impacting market fairness and retail investor returns. This regulatory shift may introduce increased volatility or reduced confidence among retail participants.
