SEC plans end to price swings
US securities regulators yesterday unveiled a long-awaited plan designed to protect the markets from volatile price swings, following the 6 May “flash crash”.
The so-called “limit up-limit down” proposal from the Securities and Exchange Commission, would require trades in US-listed stocks to be executed within a range tied to recent prices.
If approved, it would replace existing single-stock circuit breakers that were implemented through a pilot programme shortly after the flash crash.
