[求助]这种是什么期权（option）呢？

<p>is this a short position of a regular option?</p><p>but it is strange that it costs nothing.</p><p>an option should cost some money.</p><p>an executive stock option costs nothing(?)</p><p></p><p>i don't know</p>

<p>有个疑问,所需返的"部分钱"是指哪一部分.是S-K的一部分吗?</p><p>这个期权行权时是以K的价格从期权的卖方那里买标的资产吗?</p><p></p>

这不就是简单的看涨期权的空头头寸么？

<p>s&gt;k我一定要给钱吗？？？那我免费拿这个权正，我又能赚什么呢？？</p>

是不是相当于我们是卖方了？那不就好解释了

maybe a kind of conditional put option. if S&lt;K, it has no value and you have no incentive to excise it, so you need to pay a part of option fee; if S&gt;K, the holder will excise the option, and in this case the company undertake the option fee and you&nbsp;just share the benifit with the company. the company is an agency in stead of an underwriter. u and the company mutually share the cost and the benifit.&nbsp;

binary option or digital option

谢谢，大家的回答，我自己认为应该就是bs里面的digital option的一种应用，但有不完全类似的一种产品。不想再追它了。谢谢大家了。
