Date: 02/15/2000 1:52 PM Subject: Proposed Margin Changes I am writing to voice my strong objection to the proposed margin regulation changes. I am a very active investor and I think that the changes that will affect when margin calls will be generated and how they would be covered is unnecessarily punitive to active traders. Furthermore, it does not reduce risk in any way. Under the proposed changes one could trade all day without exceeding his buying power. But if that investor exceeded his buying power near the end of the day by just a few dollars, his margin call would not be based on the amount by which he exceeded the buying power but instead on the cumulative amount of the initiation costs of his transactions. It would be possible under this system to generate a multi-million dollar margin call for a trader that has less than one hundred thousand dollars in his account. This is in spite of the fact that his risk was never greater than one hundred thousand dollars plus the amount by which the buying power was exceeded. In addition that investor would have no time to transfer the funds to meet the call if it were due the same day. It is just not feasible to make the calls due without time to make the transactions necessary to produce the funds. In addition, the money deposited to cover the call need not stay in the account more than one day. Once the position that generated the call has been liquidated the risk to the account ceases to exist. I could give many other examples that highlight how unfair these changes would be but I will not take up any more of your time. Please consider my objection to these proposed rule changes which are unfair and merely serve to punish active investors. Sincerely, Matthew Panza
