I would like to encourage you to restrict retail investors access on leveraged and inverse exchange traded funds.

S7-24-15 would drive retail investors to options and short positions in order to achieve a similar risk profile. Retail investors in the options market may very well trade options at incorrectly priced levels.

As a mathematician, I expect that I will be able to profit form these retail investors buying and selling options at incorrect valuations.

Also I will be offering a service similar to inverse and leveraged funds. This regulation will help me capture the value that inverse and leveraged funds provide.
