Sources say the SEC is looking to replace the circuit-breaker system that briefly halts trading in a stock if its price rapidly rises or falls by a certain percentage with a "limit up/down" system that would allow trading to continue within the allowed range. The proposal would help in situations where a circuit breaker is triggered by an aberrant trade rather than a fundamental breakdown.
