Easy fix - put in more effective circuit breakers. Right now they are limited to the indices and certain hours of the day. http://www.nasdaqtrader.com/trader.aspx?id=CircuitBreaker

Make it so circuit breakers apply to individual stocks, and for all hours of the trading day.

For example, commodities have a 'limit up': http://www.investopedia.com/terms/l/limitup.asp

easy, and perhaps a bit naive. it is possible you may cause more market turmoil by halting only certain stocks which would push volume into ETFs, futures, options, and other stocks in the same sectors.

The markets are very interconnected and very fast moving. 'simple' solutions rarely work.
