I applaud the SEC for taking proactive action on the large trader stock swing issue. New technologies require new ways of dealing with change. The only issue I have is the United States has a tendency, sometimes, to think stock market issues of the United States only need to be dealt with internally inside the United States. However, we have a global financial system, and every country in the world also needs to see what happened here, and enact similar protections within their stock markets. Without that, global stockmarkets could totter each other in a domino effect, and nothing we do with our own regulations will help in this situation. Now that our financial systems are extemely interlocked, our regulatory bodies also need to become interlocked.
