三心三意:

2025-2-13: NVDA 138



我估计英伟达在财报前会摸到140附近去补缺口,我准备
1: 建立 ratio call spread 140-150 (1:2) at $0 credit/debit, 同时建立 put spread 140/125 (1:1), 大概 $4-$5 debit.
2: 当英伟达财报前波动到135, 再一次卖出125 put, 估计$3-$4 credit。这样和#1的put spread 在一起就成 ratio put spread 140/125 (1:2) at $0 credit/debit.
财报后如果英伟达涨,最坏结果是我的1/3仓位被160卖掉。如果英伟达只涨到150,这1/3仓位多赚10点。 如果英伟达掉,1/3的仓位在125以上的损失都被ratio put spread 保护。如果大掉,最坏结果是在110又买入1/3的仓位。
整个组合cost $0 premium.


2024-12-19 QQQ hedge


One common hedging method is using put options, though there are other strategies available. To reduce the cost of buying puts, sometimes, put spread could be used. An example is the recent QQQ trade with a 25 point put spread with a cost of $4–$5 per share. This translates to a 1% premium to protect against a 25-point drop in QQQ (say, from 540 to 515). For a hypothetical portfolio of $1M in QQQ, the cost of the premium would be $10K. If QQQ continues to drop below 515, the put spread can be rolled lower to a new spread (e.g., 515/490). Also, you dont have to protect the entire porfolio, you could, for instance, only cover 3/4 of the position, which would also reduce the premium cost.

2024-12-19 PLTR

Let's say you have decided to sell the shares and about to pull the trigger (for example, PLTR is at 75 now and you just can't see it go any higher).
Instead of selling PLTR at 75,  you can literally buy ATM  put which is likely to be expensive, let's say it costs you $8 to enter a put hedge.
Then you wait for a day or 2, and one of 2 things will almost certain take place
1: PLTR going down as you have expected, in this case, your put hedge instantly become profitable
or
2: PLTR goes up from 75 to 80. While you have a loss on your put at this point, you can sell covered call for strike price of 80, which is likely also $8 (because PLTR price has gone up)
From now on, if PLTR continues to rise, your covered call will evenutally be called away, but at price of 80, so you are eseentially selling your shares at 80. If PLTR turn around and crash, your put will still protect you, but since you have sold covered call, your premium on the put is 0.
In either case, it is better than selling shares at 75 outright.

OPST:



我卖了2年多CC,发现不管怎么小心选时间点、选strike,市场总会给我意外。那种股价扬长而去的感觉很不好。所以后来改卖call spread(卖出otm call, 买入同等数量的更otm的call),收的premium会少很多。但如果股价上涨太多,至少long leg可以带来不错的收入。

最近我又喜欢上另一种卖法了,即卖出 call ratio spread。具体操作是买入atm call,卖出2倍数量的otm call。这样收到的premium更少,甚至基本持平。 但这个好处是股价只要有稍微上涨,long leg就能有收获。 所以在股价缓慢上涨的时候,心态跟单纯卖CC很不一样,你会乐于见到股价再涨一点。

这个策略在任何时候都可以open (但IV不要太低,要不然卖不出好价钱),而不用像卖普通CC那样希望只在股价高点时才卖。 因为股价在低点的时候,反转上涨概率也大, long leg正好能发挥作用。

这个策略是负gamma正theta的,希望股价缓慢温和上涨。 如果open以后股价急速上涨,需要及时调整。一种调整方法是股价在即将达到short strike时,一点点buy to close short leg,把比例从1:2降到1:1.8或1:1.5或更低。 这样能把负gamma降下来。
举个例子, nvda现在129, 我可能会买入1倍Feb21 C130, 卖出2倍C135, 每组credit 1.5左右。 也可能卖出C136,这样credit会小于1 。可以看到premium比单纯卖出135少很多。但这个组合保留了额外获利(max gain 5)的希望 :)。 这个组合的BE点在141.5,超过141.5就亏损了。 但如果单纯卖出C135, BE点是138.8。所以各有利弊。
btw,这个策略选过期日的时候不要选ER那一两周。 ER周iv很高,表面上卖的时候能收更多premium,但被击穿BE点的概率更大,不值得冒险。

如果单纯卖135 CC, credit 3.8, BE 138.8;
如果单纯卖140 CC, credit 2.4, BE 142.4;
130-135这个ratio spread,credit 1.5,BE 141.5,跟卖140CC 相差不多,但留有额外再盈利5的希望。
看个人的风险偏好了。



这是Collar]这是Collar]为什么选择Sell Call strike price @425?
1:目前SPY收盘于420,比目前盈利稍高]1:目前SPY收盘于420,比目前盈利稍高]2:Sell Call strike price @425的另一个目的同时可以回答你的第二个问题,就是可以把Sell Call Credit to Buy Put strike price @ 410而不用pay anything out-of-pocket,即0费用达到对冲的目的。
3:Sell]3:Sell]如果市场不如预期,持续上涨,到那个价格会止损?
不会止损,如果SPY以425的价格卖掉,半年内YTD有12%左右。当然可以满意。这时候有两个选择:
<span]不会止损,如果SPY以425的价格卖掉,半年内YTD有12%左右。当然可以满意。这时候有两个选择:
<span]1:耐心地等,直到市场回调,再以心仪地价格把SPY买回来。Patience Pays Off。
2:不那么耐心地话,通过Sell SPY Weekly Put(Strike price lower than 420以保证有赚)的方式赚取premium,直到市场回调,再以心仪地价格把SPY买回来。市场总会回调的,as always。
