发帖数: 724 | 3 很简单啊，132-134视为一个long spread(花了1.2，最大亏损是成本价-1.2,最大盈利
是0.8)，134-136视为一个short spread(花了-0.7,也就是收进0.7，最大亏损-1.3,最
大盈利是收进来的0.7).
低于132时，前者全亏，后者全赢，-1.2+0.7=-0.5
高于136时，前者全赢，后者全亏，0.8-1.3=-0.5
134时，两者全赢，所以盈利是0.8+0.7=1.5
132-134时，能拿回来的钱即132的call的in the money价格，只有超过原本获得这个组
合所付出的0.5时才算盈利，所以价格需高于132.5
134-136时，能拿回来的钱即前者的2.0再减去134的call 的in the money价格，必须大
于0.5才能弥补成本价，所以134的call的in the money价格不能超过1.5,也就是说最终
价格不能超过135.5。
以上都是以6月期权到期日close价格为最终结算价。 |

发帖数: 5901 | 5 The chart is based on price at expiration. Clearly, if that price is above
50, the call spread will be losing.
If you close the position before expiration, you have to consider time
value. In that senatorial you may lose.
Actually, I think if you buy at money and out of the money calls with the
same amount of money, the out of the money calls will always have greater
combined delta than the at money calls. That means your call spread will
have negative net delta. |

j***b
发帖数: 5901 | 6 That delta is already there without you doing anything. I'm looking at the
added call spread. You said it will benefit you if there is a short term
bounce. I just showed you that's not the case, because if there is a short
term bounce, you will have to lose money on the call spread if you want to
close it. And if you don't close it, you have before expiration to lose
more money on it. |

我的option spread order （sell)的 net credit 用的是ask price （买）和bid price （卖）。也就是说是我最吃亏的价格了。为什么optionshouse还是不给fill？太气人了。
我的账号不能裸卖option。请问能不能自己先买option然后再自己卖相应的option来做spread？虽然这样手续费会亏一点，但是起码能fill。还有什么别的办法么？ |

发帖数: 1357 | 11 请问各位有经验的大大：在实际操作中，持有spread时候是怎样交易的
我主要关心的问题是spread是否会自动按组交易，以及到期日的情况
打个比方，假设long call @L, short call @H, 到期日一样，1:1
1. 一般情况下，股价如果超过H，short leg就可能被行权（当然也要考虑call的成本
），那么在过期前，股价接近H（或者稍大于）的时候是否需要关注short leg的情况，
以免被行权后还单独持有long leg呢？还是说这个时候broker会自动帮我把long leg也
行权掉？
2. 如果到期日结束没有行权，broker是否会按照当时股价和strike price自动处理？
比如股价大于H，则自动把2个leg的差价(H-L)算好打给我？还是说没有行权的option就
作废了？
3. 如果到期未行权是不作废，那么假如到期日结束时股价刚好落在2个leg之间，且没
有行权，broker是会把相应的股票按行权价卖给我，还是会直接把差价给我？
以上^

发帖数: 6806 | 12 首先，options不到最后几分钟基本是不会有人exercise的，除非傻子。
如果short提前被别人exercise,应该高兴
short到期了没有被行权，盯好after hours 股价，星期六中午expire就不用管了。
long到期了，如果itm,就会在4PM被brokers直接exercise, 有可能直接margin call,
不盯的话，星期一低开就亏大了，得特别注意。
如果otm，盯after hours股价，有可能变成itm, 那就exercise.

现在我在optionshouse有两个TSLA Mar 14 $220(long) to $235(short) call spread
现在看是赚了些不过还没赚完全，两个option很有可能都end up in-the-money
账户里只有1万多块空余资金所以单独exercise一侧是不够的， 如果我什么也不做
optionshouse说是automatically settle---这个是什么意思？我的position自动变成$
3000 cash - exercise cost么，还是会弄砸？
或者最好等周五自己把call spread卖掉更合理？

发帖数: 3320 | 21 看熊。其实sell naked call更好，但是需要比较大的margin，如果strike price价格
定的太高，卖不了多少钱，所以需要sell spread，主要目的不是为了控制风险，而是
为了更大的buying power，就是说你可以sell 更多，卖更多的钱。因为要控制风险，
所以尽量要卖的strike price高一些，就是说要卖到你认为涨不到的价格，最好卖的近
一些，5天之内到期，SPX 下周有29， 30 还有1号到期的call。目前VIX到了25，
option很贵，就是说你可以卖到好的价钱，或者卖到striking price很高任然能盈利。
你定的strike price高，所以成功率非常高，为了更好的盈利，你用spread可以卖的更
多，增加了leverage，成功率不变，但是如果市场反转到了strike price，那么你会有
巨大亏损，所以股市没有免费的午餐,控制仓位非常重要。 option的好处就是如果市场
向你预期相反的方向走，你可以调整，给自己更多的时间。 无论如何，记住一点，高
盈利必然伴随着高风险。 |

发帖数: 1148 | 26 看了下年底 Dec15 的 SPX quotes
2400-2500 的 SPX Bull Put Spread：
max gain = premium ~= 42 (if SPX > 2500)
max loss ~= 100 - 42 = 58 (if SPX < 2400)
breakeven = 2400 + 58 = 2458
negative reward-risk ratio (max gain < max loss)
2500-2600 spread (both legs are ITM):
max gain = premium ~= 66 (if SPX > 2600)
max loss ~= 100 - 66 = 34 (if SPX < 2500)
breakeven = 2500 + 34 = 2534
positive reward-risk ratio
现在 SPX 是 2436

d*******g
发帖数: 8992 | 29 嗯嗯，这是我一直在考虑的问题
我的一个call spread到期之前，很可能一条腿是价内，一条价外。
我不想留股，所以不想被assigned正股，考虑在到期之前卖掉。
现在在考虑的就是到期之前多久卖合适。
价内的离到期太远了还起起伏伏，要是原来价外的变回价内可能就被执行了。
近的话，是不是到期当天东部4点之前就可以？
也怕太近了卖不掉被assign。
所以以前我有时保险点把spread整个提前卖掉，亏一点点，因为价外的还有点时间价值
，而对于变化比较大的股票，有时价外的时间价值损失没那么快。 |

发帖数: 12 | 38 很多人计算interest spread来测度信用风险，尤其是最近次债危机以来，这种spread
显著飙升。我对金融不太熟悉，有的东西心里没有把握，特此请教，谢谢！
我计算了两个利差的长时间序列:
TED利差：3个月欧洲美元利率（即银行间利率）减去3个月国债利率。
Baa利差：10年期穆迪Baa级Corporate Bond利率减10年期国债利率，Michalel Bordo（
2008)就是用的这个。
我是否可以说，TED利差主要是测度银行间的信用风险；而Baa主要测度公司的信用风险
?对前一个还有点把握，但后者我就没底了（所谓Corportate Bond是不是也包括银行发
行的债券）？
从数据上看我发现两个利差波动趋势有一定差别，2001年衰退的时候，Baa利差加大，
但TED利差基本没有变，因此我想推断2001年当时公司信用风险很大，但银行间信用没
有出现问题。
如能点拨一二，非常感谢！很多文献都是拿这两个利差直接用，都没有给出解释，如能点拨这方面的相关背景资料，也非常感谢。

Can I say that the TED spread measures the credit risk among banks or

issued by ordinary corporates, such as Walmart and Microsoft etc)
If I am right, maybe I can say that in 2001 there is credit risk among
corporates, but there is no credit risk among banks.
