马上interview season就要开始了。刚开始肯定觉得各种call和专业术语眼花缭乱，而

1. traditional long call：就是传统的30小时call,就是从7点到第二天中午12点。再
这期间管病人，收病人。每个地方的cap 都不一样。cap就是最多收多少，有的地方没
有cap. go imagine
2. long call: 一般是早7点到晚8点，有的地方到9点。通常只在5点之后收病人，因为
白天有很多resident team,一般大家都分摊了，不至于让你一个人收。但周末除外。
3. Night float: 就是有一组resident/intern晚上8／9点到第二天7点。负责cover病
人，加收病人。还有就是有无cap。
4. short call：一般是周末cross cover同组另外一个intern的病人。一般会有

对于buy call或者buy put的party我可以理解他们通过call或者put
的杠杆作用来赚钱。
但我不明白的是sell call或者sell put的party是什么心理呢？
他们收获的只是卖出call或者put的钱，而一旦卖出call后股票涨价
或者卖出put后股票降价，他们都可能损失巨大，
这种明显处于倒杠杆地位的事情为什么还要做呢？
那么sell call或者sell put还能有什么其他的作用？

发帖数: 176 | 17 请教一下用covered call做高回报长期投资的可行性。
如果每个月卖一次，是不是就能获取稳定的高回报？
比如最近买了$10的xlf，卖下个月的$12 covered call，大概$0.3
这样每个月回报是3%，一年不就36%？
除去手续费，也有30%左右。
如果xlf跌了(不会再腰斩了吧)，估计卖不到0.3, 就找个稍低点的。
如果xlf涨了，甚至被call走，收益更高。接着买xlf，再卖call。
这样比401k里hold股票强的多啊。
不知道以上方法可行吗。如果可行，岂不是太容易了。
一般401k和ira都不能卖call吧。华尔街太坏了。
如果上述方法可行，还不如不放401k，税后自己投资好了。 |

发帖数: 176 | 18 我是觉得那些大机构长期持有股票，肯定卖call，每月有固定收入。几乎白拿啊。
可是我知道一些学校的基金，他们持有的股票就不卖call。有点奇怪了。
当然他们说买股票就买，说卖马上就卖了。
对于一些基金，只要没有赎回，就算股票跌了，可以继续持有，接着卖call。
个人投资为啥算了？看不起这点回报？
对于长期持有，买了股票卖call，和为了卖call买股票，好像差别不大啊。呵呵
前提是觉得现在是接近底部。 |

发帖数: 868 | 19 不停卖covered call根本就不是在“投资”股票，而是相当于在开保险公司，你持有股
票就是你所需要的本金，每年偶发事故出现时的赔付（股票暴跌你亏的钱）减去你卖
call收的钱就是你提供保险服务赚的premium。
options是一种流动性非常好的保险，人人都能提供，所以它的premium非常低，你作为
保险提供方如果不上leverage的话（你卖covered call的话就只是1:1而已）估计根本
连银行利息都beat不了。
大机构之所以能卖options赚钱是因为人家能上leverage，人家手上有1B本钱就敢卖5B
甚至10B面值的各种call和put，总是东方不亮西方亮的，最后实在不行大不了破产，你
这个私人小作坊型保险公司怎么跟人家竞争？
你如果真的能看准现在是接近底部，当然是坚决hold股票，卖call的话可不合算。 |

前提：除去分红因素，也不考虑由于流动性问题带来的spread损失。
买1个call和买100股stock加一个put，是否等价？假设行权价格相当。
我的理解是等价的：call上的time value decy和put对冲，而call的上升潜力等于
stock，call的downside risk limit等于put的保护作用。
但如果是这样，买后一种组合岂不是很亏？因为是双份commission，还多占了很多资金

赚到了额外premium，而且你还可以继续写call
但是如果股价上升超过了strike price，那么你的股票可能会被call走，你损失的就是

首先声明，这个技术只适合于指数股，ETF，不适合个股。
前面15天，第二个月的out of money的CALL，这样的CALL贬值快，而且价格适中。
后面15天，换成当月的at the money的CALL，这样的CALL贬值快。
前面15天，就好比是一辆新车的第1-2年，价格飞快贬值。
后面15天，就好比是mortgage 的后期，Balance 成指数函数下降。

发帖数: 5901 | 31 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. |

Let's see the latter separately.
covered call(45): sacrifies the potential benefit(ref-price is more than 45)
with the compensation of option premium.
Bull call(40,45) spread: has limited loss and benefit. If ref-price goes
down(until 40), he will lose more on this spread for sure. However, if ref-price goes

发帖数: 1136 | 37 希望不等于现实。如果你认为downside protection一文不值，那是十分错误的。
在大萧条时跳楼的破产投资人们肯定不同意。他们付出了生命的代价。
事实上，买call是很好的投资方法。如果你用options来投资，那一定记住，市场是有
偏差的。大部分投资者会卖covered call来提高回报，或者买put限制亏损。因为这样
的bias，使得call的价格偏低，而put的价格偏高。所以反着去做，买call和卖put会使
期望回报率上升一到两个百分点。Goldman去年有一篇研究报告说的就是这样的
strategy。
另外，你关于强制止损的论点不全面。假设这个100元的股票先掉到80，然后涨到150，
你如果强制止损了，那绝拿不到最后。可是买call的话，就没有问题。
