Abstract

Using five-minute data, market volatility in the Dow Jones Industrial Average is examined in the presence of trading collars. A polynomial specification is used for capturing intraday seasonality. Results indicate that market volatility is 3.4% higher in declining markets when trading collars are in effect. Results also support a U-shaped intraday periodicity in volatility.
