14 breakers
When the market has fallen to a certain extent, the measures taken to suspend stock and stock-stock transactions are usually based on a percentage decline over a given period of time. For example, under the new breaker introduced by the new york stock exchange in spring 1998, stock exchanges were suspended when the dow jones industry average index fell by 10, 20 and 30 per cent. On the first day of january, april, july and october, the new york stock exchange made quarterly adjustments to the required drop point levels. The breaker was first introduced after “black monday” in 1987 and was revised after the market collapsed in 1989. Breakers are subject to frequent changes, but usually include suspension of transactions and price restrictions on stock-indicated futures transactions. The purpose of circuit breakers is to prevent a sharp fall in the market by rebalancing purchase orders。
