问题 单项选择题

关于试点初期保证金的计算原则,下列原则不正确的是()

A.以较大可能性覆盖连续两个交易日的违约风险

B.对实值期权在收取保证金时考虑减掉实值部分

C.同时平衡违约风险和市场爆炒风险

D.结算参与人向投资者收取的保证金不得低于登记公司向结算参与人收取的保证金数量

答案

参考答案:B

解析:试点初期,保证金计算原则:原则一:以较大可能性覆盖连续两个交易日的违约风险。原则二:对虚值期权在收取保证金时考虑减掉虚值部分,提高资金效率。原则三:结算参与人向投资者收取的保证金不得低于登记公司向结算参与人收取的保证金数量。原则四:同时平衡违约风险和市场爆炒风险。保证金的收取直接影响出现卖方违约的风险,间接影响市场爆炒的风险。保证金收取高,则违约风险小,但深度虚值期权的卖方成本高可能导致供给不足,市场爆炒风险大;保证金收取低,卖方力量充足市场不易爆炒,但卖方违约成本低,违约风险大。设计时同时平衡这对矛盾。

When Julio Diaz stepped off the subway after work one night, he was simply planning to go to his favorite local diner for a meal. But when a teenage boy approached him with a knife, Diaz knew the evening was about to take a more dramatic(巨大而突然的) turn.

The young man demanded Diaz’s wallet, and Diaz passed it over without objection(异议). But just as he turned to walk away, Diaz called, “Hey, wait a minute. You forgot something.”

The young man turned around, surprised.

“If you’re going to rob people for the rest of the night, you might as well take my coat to keep warm.”

The teenager looked at Diaz in disbelief, and asked why he would do such a thing. Diaz replied, “If you’re willing to risk your freedom for a few dollars, I guess you must really need the money.”He said he was heading out for dinner, and that he would be happy to take someone with him.

The young man decided to take Diaz up on his offer. As they were sitting at the table, the manager, dishwashers and waiters all stopped over to say hello to Diaz, and the young man was amazed at his popularity.

“Haven’t you been taught that you should be nice to everybody?”Diaz asked him.

“Yeah, but I didn’t think people actually behaved that way,” the teenager replied. Thanks to Diaz, he was beginning to see that kindness wasn’t so strange, after all.

When the bill came, Diaz told the teen that he’d have to get the check. After all, he still had Diaz’s wallet.

But the teenager put the wallet on the table without a moment’s thought, and Diaz treated him to dinner. Diaz also gave the would-be robber a $20 bill — in exchange for his knife. “I figure, you know, if you treat people right, you can only hope that they treat you right,” Diaz said.
