这个策略是我翻译网上的: (未名发帖也太烂了, 总是断行)
比如你50块买的股票, 现在跌到40了,你最好的挽救这艘沉船的方法
就是用ratio call spread策略. 这个策略适合你的损失从-10%到-50%不等.
如果下面股票开始涨了, 你能迅速回本, 但是继续跌的话, 就跟你原来持有一样.
也即买1个at the money, 40块的call, 同时卖2个45块的call(这个strike 45的
选择,一般是40加上你损失的一半(也即50-40=10的一半,5),
使得买/卖call的成本基本互相抵消.
之所以叫ratio call spread, 是因为买1份call, 卖2份call, 比例ratio是1:2,
叫spread,是因为有同时有买和卖.
一般从2个月到期的call开始选, 使得买卖call的成本相抵消,
最长到1年. 因为时间太短的话, 没法使买卖call的成本相互... 阅读全帖

Donald Trump’s protocol-breaking telephone call with Taiwan’s leader was
an intentionally provocative move that establishes the incoming president as
a break with the past, according to interviews with people involved in the
planning.
The historic communication — the first between leaders of the United States

我看了下昨天spy期权的收盘情况, spy收在128.4
Jul 15到期, strike=128的call收在2.5, put收在2.9
这个call的implied volatility是14%, put的iv是20%, 明显put高估
根据put-call parity等式: call+K/(1+r)=put + stock
所以就存在无风险套利:
short 128 put @2.9
buy 128 call @ 2.5, short stock @ 128.4
总共利润是 0.8 $ , 不管到期股价是多少
$0.8 / 128*12=9.3% 年化利润率
因为是无风险利润, 加杠杆!!!!

这样套利空间就压缩了, 大概只有0.2, 只适合大资金搞了

上次的期权风险初探从趋势上讨论了影响option价格的一些因素如方向(delta), 加速
度(gamma),振幅(vega)和时间(theta)等。我们在这里先量化delta: 它是指股
价变化对期权价格的影响。如果股票上涨$1, 某个Call 上涨80c,则该Call的delta为0
.80, 某个Put 下跌30c,则该Put的delta为-0.30。delta实际上是测量了期权价格和股
票价格的关联度,call的delta在0和1之间,而put的delta在-1和0之间。

今天遇到个bad line call的,以前就打过,知道他line call不怎么样。但是偶
实力强一些,所以就没怎么计较。有一个例子是偶一个界内6英寸左右的ace球
被他called out. 要知道偶一年才能发5个ace, 你们可以想象偶多郁闷。
今天开始,第一局一个压边线球就被他called out(他就在跟前)。然后2-2后
的一局,偶一个正手偶感觉是压底线的winner, 他问偶is it in. 偶说你的call.
他就called out. 然后同一局的破发点, 偶把他拉到反手侧后攻正手侧,球
落在线内,刚好没有压线的样子。他直接called out. 偶忍不住了,说it was
actually in, but it's your call. 这个是偶史上第一次抱怨line call.
然后他改了call, 不过感觉气氛有些紧张。偶也有些气,所以接下来很卖力的
连赢了几局到5-2.
后来好一段他的call都很好,知道第二盘快结束时候才又恢复了几个有争议
line calls. 偶不明白这个人是没有经验还是故意。

来自主题: Stock版 - 超快速估算ATM call的贵贱
上次我发了一个帖子, at the money call的iv可以用下面这个近似公式, Brenner and
Subrahmanyam (1988)
iv = sqrt (2*pi / t) * C / S
= 期权价格C / [ 0.4 * 正股价格S * sqrt(t) ]
最近我想到这个公式的一个直接的应用, 就是快速估算ATM call的价格是便宜还是贵,
也即call价格是spot price S的百分之多少.
因为C/S = iv / factor, 而其中的factor只跟t, 天数有关, factor(t)= 1 /
[0.4*sqrt(days/360)]
举例来说, 30天到期的ATM call,factor = 1/0.4/sqrt(30/360)= 8.7倍, 所以如果年
化的iv是30%的话, 30%/8.7=3.5%,那么这个call的价格就是spot价格的3.5%. 也就是说, 如
果你买的这个call到期不值钱的话, 就相当于你买正股, 并在entry price下面3.5%的地方放

怎么WRITE a covered calls/naked calls.
是不是自己先要有那个股票,或者要用市场价买CALL的股票,然后才能WRITE A CALL。
以后就不用管了,等到期的时候或者之前,CALL的买家执行CALL的时候,就自动把股票
按CALL的STRIKE PRICE卖给CALL的买家?
covered calls/naked calls又有啥区别呢。

来自主题: Tennis版 - 比赛中line call的一个盲点
打了很多single比赛,关于line call的感受当然很多
基本上看清楚的in or out都会call的很清楚,看不清楚也就不叫了
但是发现从底线附近call 边界球其实是一件很tricky的事情
尤其是被调动到一个角而看到对方的回球飞向自己另一侧的边线时
如果是on the line,眼睛看到的却是“很明显”的out
这样的情况出现了三四次,有一次我call了对方out,对方提出质疑(记不清是不是改
判),之后对方又call了我同样的球,而我是直线球所以看得很清楚。我俩应该都是
call的很松的人。
还有一次是对手几乎是我见到call的最松的,却也在这个位置出现了call球失误。
again,因为我打的直线球,所以我看的相当清楚,而他站在底线另一边。
我想应该是视觉上的一个误差,在擦线球上会出现很明显的误判,感觉直线球的call
失误率更高
结论:从底线一侧call另一侧出界球,只要不是“看到”出界两个球距离就不要call
out.
不同意的可以扔转~

"同时covered call卖一个DEC 15的 160 call (卖Call得15.89*100)"
你卖的call 是12/19/2015 expired 160 strike 的call, right?
如果到了12/19/2015, SPY close at 161, 你的SPY share 就会被call 走。 在这个
日子之前, 虽然SPY option 是American Style option, 但只要这个call 还有 time
value, 你的broker一般不会assign 你的call, 也就是说你的SPY 会一直保留。 除
非SPY飙涨, 你的160 strike 的call变成 deep ITM, 你的broker也许会为了吃SPY的
dividend, 提前assign。 但这时这个call 一定没有time value 了

(1) 你的问题其实应该到股版去问
(2) option 被call 走 = 就是指把我手上的100股SPY拿走,我也不用买回来了此前
卖掉的Call了。 你的case, 现在broker不会call走你的SPY,这个call全是time vaule
, 没人那么傻。

的LEAPS 好呢,还是卖下个月或者2-3个月的Call好呢(这种Option都是做Hedge为目的
的)"..
Hedge 都是买put 来hedge 你手上的equities, 卖call是为了赚call 的time vaule。
(4) Covered call 的gain 是limited。 当hit 你的max gain时, 你要么一起close
(卖stock + 买回卖掉的call), 要么买put 来protect 你手上的stock, 以防
stock 突然掉很多。

这个策略是我翻译网上的: (未名发帖也太烂了, 总是断行)
比如你50块买的股票, 现在跌到40了,你最好的挽救这艘沉船的方法
就是用ratio call spread策略. 这个策略适合你的损失从-10%到-50%不等.
如果下面股票开始涨了, 你能迅速回本, 但是继续跌的话, 就跟你原来持有一样.
也即买1个at the money, 40块的call, 同时卖2个45块的call(这个strike 45的
选择,一般是40加上你损失的一半(也即50-40=10的一半,5),
使得买/卖call的成本基本互相抵消.
之所以叫ratio call spread, 是因为买1份call, 卖2份call, 比例ratio是1:2,
叫spread,是因为有同时有买和卖.
一般从2个月到期的call开始选, 使得买卖call的成本相抵消,
最长到1年. 因为时间太短的话, 没法使买卖call的成本相互抵消.
下面是pay off的图. 原来你不用这次策略,只等反弹的话, 需要50,才能回本(虚线在50块
才和零轴相交), 但是采取这个策略后, 股票涨到45就能回本了.
所以你看到黑线是... 阅读全帖

来自主题: TexasHoldem版 - Made a Hero call yesterday.
My first super hero call since playing Electro. Only about 100$ in the
pot , have to call a near 400$ all in with only pure bluff catcher. But
going through the logical process, only thing he can have is missed draw. If
you have a monster ,why bet so small on the turn with 2 opp in the pot and
the board is draw heavy. I usually do not like
this kind of call since bad risk/reward, but this one I decide to trust my

这一年多以来迷上了Stevie Wonder。熟悉他的童鞋自然知道他的江湖地位,不熟悉的
去wiki,反正就是现代流行界数得着的顶级的几个吧。
很喜欢他很多歌,很想唱,想唱系列。但是,太太太难了…………高音是一方面,那个
味道,节奏,转音,腔调,情绪。只能追求完成度,就算加点表达面,也是自己的,没
法模仿。当年iTolduso说,你胆儿太肥了,敢唱他的?我说,我就是随便一说,真不敢
承认……
这个系列从他最出名的一首街歌开始,唱出来这个,也不知道另外其他的能不能完成,
弄一首是一首吧。
小心,有鬼哭狼嚎,实在是高,高过D3,就是求不破而已,避雷针自带。
I Just Called To Say I Love You

No chocolate covered candy hearts to give away

来自主题: Investment版 - 新手请教个Covered Call的问题
哇,太感谢了!码了这么多字!
是的,是12/19/2015 expired 160 strike 的call。
我忘记在哪里看到说如果SPY分dividend,就一定会被Call走。请问这里assign我的call
,是不是就是指把我手上的100股SPY拿走,我也不用买回来了此前卖掉的Call了。
另外,如果想波段操作SPY,就是买在自己认为的阶段低点,同时是卖这种OTM的LEAPS
好呢
,还是卖下个月或者2-3个月的Call好呢(这种Option都是做Hedge为目的的)。
同时如果过段时间,SPY涨了,我想抛了,也同时想了结此前卖掉的Call,那就要卖SPY
,买回来同一个Strike,Expiration的Call对不?但此时之前的Call就ITM了,虽然
Time value会小下去,但有没有可能说,我做这个波段还不如不做,因为有可能买回来
的Call会特别贵?
问的问题很入门,谢谢pooh的讲解!

来自主题: Stock版 - 请教一个Reg T Call的问题
收到了一个Reg T call,不明白为什么会被call,因为我的账户还有buying power,也
还可以买。以前收到Maintenance call都是因为buying power为负了。问了broker,但
还是不明白。麻烦明白Reg T call的帮忙解释一下。我的是margin账号,那天我先是
cover了一个short position,然后又买了一个股票。现在Reg T call的就是那天买那
个股票的金额。
以前收到Maintenance call,只要卖点股票或者一些带margin的股票涨起来,buying
power变正了,就可以解决了。但这个Reg T call只有以下两种方法来解决:
* Deposit of Cash in the entire amount of the call.
* Deposit of Margin eligible security(ies) valued at 2 times the amount
of the call.
请问这种情况是不是卖股票都不行,只有靠转钱(或者转股票
?)进去才能解决?谢谢答复!!!

来自主题: Stock版 - 新手问一个covered call的问题
还有问题,望大牛赐教!
我用的scottrade,卖了一个股票的covered call。结果卖了之后,股票价格在不断上
涨,带动了call的价格也在上涨,然后我卖的这个call本身开始亏钱了。
以前从来没有卖过covered call,不知道从现在开始到OE day,这个call option的图
形大致是怎样的啊?如果股票一直飚,我卖的这个covered call就会越亏越厉害啊?我
理解如果到OE那天如果股票价格没有达到strike price,我就白赚了卖covered call的
premium。
可是如果股价真的hit甚至超过了strike price,我的利润真的是(stock price -
strike price)*shares + 我卖covered call的premium - 各种手续费么?搞不清楚
covered call本身价值岁市场的变动会对我的最终利润有什么影响...

上次讨论了短期策略利用DOTM (Deep Out Of The Money) Call来赌 ER。当然赌
earning report的各种各样的期货玩法。赌剧烈运动的可以bet大涨 (long call),大
跌 (long put), 大涨或大跌 (long strangle/straddle 或 short iron codor),
也可以bet小幅波动 (short strangle/straddle 或 long iron condor)。请牢记无
论选择那种玩法,您的对手(买方/卖方),Market Makers一定计算好了的赔率并设定了
对他有利的价格,笑到最后的很可能是他们。
在短期策略中, theta (time decay) 对call持有者是个巨大的威胁,股票必需在很短
的时间内快速上扬。这里theta用来表示时间对期权价格的影响。如果theta指为-0.80

前文讨论了利用Near The Money Call在股票维持上涨动能时盈利, 提到了自创的3M理
论来pick,即 Momentum, Multiple non-correlated evidences 和 Market。
1)Momentum(动能): 股票正处于突破后的上升趋势中, 有良好的TA指标和基本面。
2) Multiple non-correlated evidences (多个互不关联的证据),如:
大牛, Investors Business Daily 或 Barron’s 推荐, 如 stock on IBD Top 50 or
section leader
客观观察到的经济现象: 如CMG要排长队,LD最近爱到Nordstrom 扫货,街上和
parking lot里某种牌子的电动车大增,隔壁某公司忽然大举扩张(通常是并购前兆)等。
Outperforming sectors: 如去年的新能源,生物科技和互联网等

前些天由大牛指教买入了UNH的的call,周五出了。尝到了些甜头,想请大牛们帮忙分析
下买call的风险
UNH
2月9日 股价为107.xx, Mar 20 $110 call 我以$1.80的价格买了10个
2月20日,股价为112.xx, 我在$3.70的价格卖了,当然后来价格去到了4块。也就是说
我在2星期内投入翻番了。
那现在分析下买call和买股票的区别
同样,如果在9号买UNH 100股,投入需要$10700元,在20号卖出,利润$500
买call要达到相同的利润的话, 只需要投入$540,买3个call,连个零头都不到。
大家买股票自然是希望股票涨,但如果股票跌了,哪个损失大呢?
假设两周股票内跌了5块,也就是损失500,但是call的损失最多也就是完全损失掉了,
也就是500.
如果股票不动了,call就完全的损失掉了,而股票的价值还在。但这种情况可以通过
put spread补一点钱回来。
买股票投入的资金太大了,像什么AAPL, TSLA, XOM,SPY,IBB都好贵, 小账户折腾不起
啊,只有买点call了。
不知道我分析得对不对。请大牛指点。谢谢。

自己总是不想动脑筋,老是痴心妄想,不劳而获,或者少花力气,赚钱,也就是傻瓜赚
钱。
傻瓜赚钱法之一,就是买VXX,然后买VXX的COVERED CALL。
本人胆小,因为VXX大起大落,不敢买太多,就一千股VXX,价格28.11,每周卖一次
COVERED CALL。
第一周,卖了价位28的VXX COVERED CALL,价格五毛,到期时,VXX价格低于28。
第二周,运气比较好,VXX COVERED CALL卖了八毛五,这个周五如果VXX价格还是低于
28的话,还可以卖第三周的COVERED CALL。
到目前为止,五毛加八毛五,总共进帐一块三毛五,乘以一千股,就是一千三百五十,
除去交易费,总要赚一千多。
可以找一个大起大落的股票,买进,然后出卖该股票的COVERED CALL,大不了被CALL走
,如果不被CALL走,可以每一周继续卖COVERED CALL。
算是本傻瓜赚钱法之一。
请大家不要见笑,赌博投机股市,赚钱第一。
是不?
