I have been trading inverse and leveraged ETF's for at least 6 years. I have read the prospectus and FULLY understood how these instruments work. I believe most investors that use these instruments have done the same homework that I have.

I believe if you add new regulations that make it harder for brokerage firms to offer these, then they may not offer them, or offer fewer of them.

I would request that you don't punish the many that know how and when to use these instruments for the few that don't.

Thank you for your time,

Sincerely yours,

Thomas Chun
