As a small investor, I am more and more concerned about my investment interest which are not properly protected. Specifically, I have a huge problem with large investors who put my account into tremendous risks. And there is no enough regulations to protect me and many other small investors. For example, the institutional and large investors are able to day trade without ANY limit. If they blow out a brokerage firm, many accounts of small investors go down with it. Why there is no sufficient regulation? Why? Mr. new SEC chairman, you vowed to protect small investors. Now it is time to act!
