炒股學習筆記(8)--hedge(ratio call spread, ratio put spread)

(2025-02-13 19:49:12) 下一個

(5)第四種策略

https://bbs.wenxuecity.com/tzlc/2011244.html

When NVDA is 150, sell its 150 call + sell 145 put 

You are likely to collect $15 on the call, and $10 on the put for a total of $25 credit.

In this case, NVDA drops right after it hits 5th wave high. Anytime NVDA stays above 120, you essentially end up owning more at 120 for a profit (because you have that $25 cedit) --- You are going to buy more shares anyway. When NVDA dropped below 120 due to deepseek, you can sell more put at 120 for another $10.

In a unlikely case if NVDA keeps going up after 150, you are well covered all the way to 175 (also due to that $25 credit). Because this is 5th wave, it is very unlikely NVDA can go above 175.

最後說一句,這些各種各樣的Hedge,我的大方向都是避免股票被行權賣掉。因為股票才是最終的回報

問:opst 和三心,請教怎麽決定賣CC的時機,是看IV,theta這些嗎?

答:我很少隻賣cc. 我hedge的時間一般由2點決定:Big event such as ER, or 5th wave。去年QQQ around 540, 和TSLA460-480 都是因為5th wave 去hedge的

我現在用1 在英偉達上。如果它漲超過160我就認了(賣1/3的positiin) ,就是下麵兩張圖。特斯拉如果漲到400上方,我會用3

(4) 第三種方法(3):1,2是對前麵的重複性總結 3才是第三種方法。

首先,讓我們總結之前提到的兩個策略。

1:ratio call spread + ratio put spread 
該策略適用於你認為短期上漲空間有限的股票(比如說前2天NVDA的例子,它在財報後漲破160 unlikely),同時你願意在股價大幅下跌時買入更多(本例中,若跌至110)。

2: Bull put spread -- 你認為某隻股票當前價格有吸引力,但擔心進一步下跌風險。建立 Bull put spread允許你在股價上漲時獲利,同時如果股價大幅下跌,你也能以較小的風險獲得該股票。

3: Now let's look into 3rd scenario: 如果你想保護股票的下行風險,但又不確定股票的上漲空間。你不想使用(Covered Call) -- 因為如果股價持續大漲,你可能會失去所有股票,該怎麽辦?

例如,如果 TSLA 下周漲到 400,你感到非常擔憂,但又不想直接在 400 賣出Covered Call。 在這種情況下,你可以考慮 Bear Call Spread + Ratio Put Spread。

Bear Call Spread: Sell TSLA 400 call and Buy TSLA 420 call, with a credit of $9
Ratio Put Spread: Buy TSLA 400 Put and Sell 2 TSLA 360 put, with a debit of $9
在這個組合策略中,你利用 Call Spread 的credit 收入來覆蓋Put Spread的成本。

如果 TSLA 繼續上漲,你最多損失 $20 的利潤(從 400 到 420),但即使 TSLA 漲到 450 或 480,你仍能保留其餘所有利潤。
如果 TSLA 繼續下跌,你在360 之前都有完整的保護,並且在 320 附近實現盈虧平衡(也就是說,相當於沒有進行對衝)。但是,你必須願意在 320 附近額外買入更多股票。
如果你對在 320 買入額外股份感到不適,那麽可以把Ratio Put Spread改為普通的Put Spread,避免承擔額外買入的義務。
這個策略最大的優點就是,你不用擔心簡單的covered call 所照成的股票被call 走的情況

(3)第一種方法。兩個例子 (2、15、20250)

(2)一個複雜的hedge (2/13/2025) by 三心三意

https://bbs.wenxuecity.com/tzlc/2010040.html

我估計英偉達在財報前會摸到140附近去補缺口,我準備

1: 建立 ratio call spread 140-150 (1:2) at $0 credit/debit, 同時建立 put spread 140/125 (1:1), 大概 $4 debit.

2: 當英偉達財報前波動到135, 再一次賣出125 put, 估計$3-$4 credit。這樣和#1的put spread 在一起就成 ratio put spread 140/125 (1:2) at $0 credit/debit.

財報後如果英偉達漲,最壞結果是我的1/3倉位被160賣掉。如果英偉達隻漲到150,這1/3倉位多賺10點。 如果英偉達掉,1/3的倉位在125以上的損失都被ratio put spread 保護。如果大掉,最壞結果是在110又買入1/3的倉位。

整個組合cost $0 premium

(1)play call ratio spread on TSLA (2/13/2025)by 三心三意

https://bbs.wenxuecity.com/tzlc/2009226.html

For example, if you hold 100 shares of Tesla, you could

1: Buy 1 March 14th 350 call for $19.5

2: Sell 2 March 14th 380 call for $9.5

The net cost of the above transaction is $0.

If Tesla rise to 380 before 3/14, you can take the max profit of all the spread, which is $3000. You breakeven point would be 410 --- the loss on the covered call will equal to the gain on the spread. In this case, you just close both positions with no profit, but the underline stock is now 410 so you are still better off. 

This strategy allows you to essentially buy the call spread with zero cost for this short term bounce.

I did this yesterday on 340/370, but I think it is not too late to play 350/380
