Answer:
7%
Step-by-step explanation:
In Microeconomics, circuit breaker can be defined as a financial regulatory measure or instrument used by stock exchange organizations to temporarily halt trading on an exchange and to prevent stock market crash. The circuit breaker is also referred to as trading curb and it is used to curb panic selling in the stock markets, which eventually prevents collosal losses and speculative profits in a very short period of time.
The "circuit breaker" on the domestic equities markets to reduce price volatility is INITIATED when the Standard and Poor's 500 Index falls by 7%. The circuit breaker rule states that, if the Standard and Poor's 500 Index falls by 7% from the closing price of the previous day: the listed equity on the domestic equities markets will be shut down for 15 minutes, so as to mitigate price volatility. The 7% is the level one (1) of the circuit breaker levels for the the Standard and Poor's 500 Index (S&P 500 Index) on the stock markets.
