SPX OPTION对一般人没有限制,根本就不是机构专用,你不要在这里误导。另外,SPX
premium和SPY都是一样的,根本不存在SPY premium更多这一说,请你不要误导。cash
settled european style option是优势。SPX option一周至少三次,多于SPY。SPY
是SPX的十分之一,操作SPX option对资金是有点要求,但是要求也不是太高。你自己
愿意操作哪个是你的自由,但是最好不要误导别人。

举个例子,比如TWTR,在上周季报之后TWTR大涨,一下子涨到了16块多。我认为TWTR短
期内还会再涨,所以就买了一些TWTR的call option。上周TWTR当天涨到了16块多,我
准备long TWTR。我买了5/5到期的TWTR 15的call,属于ITM call。买15块钱的call是
因为发现当时15块钱的CALL extrinsic value只有0.1 - 0.2之间,而我认为TWTR要涨
肯定不会只涨这么一点0.1 - 0.2基本上处于在日内波动范围之内,所以我花1.4买了5/
5到期的TWTR 15的call,大部分都是intrinsic value,基本上等同于我只用1.4美元一
股买了16块多一股的TWTR股票。几天TWTR涨到了18.3一股,而我买的5/5到期的TWTR 15
的call也涨到了>3.3。这个基本上相当于短期内应用了超过10倍的杠杆(16/1.4>10)
long TWTR股票。同时最大损失也不过就1.4美元一股。其实就是相当于long TWTR with
protective put。
当然也可以选择买OTM option,价格更便宜。... 阅读全帖

其实特别简单。
就是吃一段中间肉。
option定价原则基本就是time + 各种parameter,date to expiration是一个基本原则
,越近,time越骤减,而越近,risk越高。
他的策略就是,
我搞一段50天的,然后吃30天,20天就close,这样不会hit被强行执行。赚的premium
就是那些有volatility,但是慢慢小。
这个策略理论上面不错,缺点:
1. 如果是单边行情,比如一直涨,一直跌,这个30天就搞挂你。
2. 如果是earning date靠近,越靠近earning date,option越贵,那么short premium
是跟你自己走反。
独家秘笈:
这种策略在没有波澜下比较合适,不适合接近earning的。
然后!最重要的。
option定价有趋势,某个parameter突然高了,是代表了一种趋势,某个option突然
large volume,是趋势!

“IV固定的情况下,options定价太高” 这个说法不正确。
IV (implied volatility) 实际是 volatility implied by option prices...
供不应求、买方把某个 strike 的 option price 给 bid 高了,
该 strike 的 IV 就升高了。IV 就是 option price 的反映。

我有twtr的股票仓位,从16块hold到现在,因为觉得股票还有上涨的可能,但是觉得$
25价位是个坎不是那么容易越过,担心股价有可能短期下跌,所以今天买了点put
option来保护,我的心里卖价是$25,所以strike price就是定的$25,OE是1月19日,
如果股价涨到$27刀,我打算出掉半仓股票,option的cost就当是花钱买平安,如果股
价跌倒25以下,option上赚的钱就当是弥补股价下跌带来的损失。第一次option操作,
真心请教各位大牛是否合理。谢谢!🙏

那个$1是指strike price. 就是你以后可以在一定时间内(比如十年)以$1/股的价格认
购公司股票.
这个具体说来有些复杂, 不是一句两句能说清, 简单来说:
startup的估值大约有两种
一种是按照fund raising的价格来估计每一股多少钱, 比如说某一轮融资, 某投资方投
30万获得10万股, 那么每股就是$3(注意这一般是preferred share价格, 不是common
shares, preferred share更值钱, 但是这里不细说这个区别).
另一种是409A valuation, 也就是一定意义上的客观估价. 员工拿option, strike
price好像都是按照409A的估价, 也就$1/一股.
假若若干年后, 你的option全部释放了, 当时股票是$10块钱一股, 那么你的option就
价值
5万股 x ($10 - $1) = $45万
这些option现在而言, 简单的价值计算就是
5万股 x ($3 - $1) = $10万. 当然这里还是忽略preferred share和common share的区别

Intuitively, people should be able to get an idea of the public opinion
about stock price in a month.
Assume at the money option, call option price is far expensive than put
option. which means everyone think the stock will go up so call at the money
cost more than sell at the money.
So the expected return should be positive.
But I heard prof. mentioned that option price only related to the volatility
, not depend on future return, so what's the rational behind it?

One option should be optimal:
1. Less transaction fees.
2. How the index is constructed is unknown here. The index might not be the
simple sum of the 30 stocks.
3. The index is likely to have higher liquidity than the individual stocks.
Thus, the option on the index is supposed to have higher liquidity than
options on individual stocks.
4. The relationship among 30 options could be very hard to explore.

the price of a binary option is the risk-neutral probability that the option

these call/put options have in-symmetric pay-off. When in the money, option
pays, when out of money, option pay 0.
So when vol increase, underlying price move more, more chance to in the
money, pay off linearly increase, also more chance to out of money, but out
of money is 0 payoff anyway. So, overall, the option price increase.
this applies to both call or puts.

I can understand your statement for the perpetual options. For the perpetual

就是说在无jump情况下,option价格=用来hedge option的portfolio A价格=C(S_0, 0),
现在有jump了,portfolio A不能完全hedge了,会亏钱。
所以要在portfolio A的价格C(S_0, 0)上面加上一定的premium,
