BREAKING DOWN 'Curbs In'
Trading curbs are usually used to reduce the sudden movement of a security's price. This is done to reduce the volatility of the market. Some people believe that curbs actually increase uncertainty and limit the ability of the market to reach an equilibrium price. Taking curbs out, they think, would allow the price to fall or rise to a market-determined level.
