Call Price vs: Stock Price: Understanding the Link update - FasterCapital

 

Options reflect expectations about the underlying asset, and options are commonly priced using the Black-Scholes model:

Black Scholes equation

N(d1) and N(d2) are probability functions, S is the spot (current) price of the asset, K is the strike price, r is the risk free rate, and T-t represents time to maturity. Without getting into the mathematics, it suffices to say that higher volatility or expectation of volatility increases the perceived riskiness of the asset, so call options are priced lower and put options are priced higher.

Think about it intuitively. If the stock is more likely to go downwards, then there's an increased chance that the call option expires worthless, so call options must be priced lower to accommodate the relative change in expected value of the option.

Puts are priced similarly, but they move inversely with respect to call option prices due to Put-Call parity. So if call option prices are falling, then put option prices are rising (Note, however, that call prices falling does not cause put prices to rise. The inverse relationship exists because of changes in the underlying factors and how pricing works.)

So the option action signifies that the market believes the stock is headed lower (in the given time frame). That does not mean it will go lower, and option traders assume risk whenever they take a particular position. Bottom line: gotta do your own homework!

Best of luck.

Option Price vs. Stock Price - AskMen

Intrinsic Value vs. Time Value: The intrinsic value is the difference between the underlying stock price and the exercise price. The time value is a premium allocated to the value of the option for its duration period. The total value of the option is the sum of the intrinsic value and the time value. Once it expires, the value of the option is only the intrinsic value.

  • At-the-Money: Term used to explain that the option is neutral. This means the exercise price is equal to the underlying stock price for a call option, or that the exercise price is equal to the underlying stock price for a put option.

    relationship option vs stock price


    An option's price is the result of properties that belong to both the underlying stock and the terms set out in the option. The major factors are:

  •  
  •  
  •  
  •  
  •  
  •  
  •  
  •  
  •  
  •  
  •  
  • The market price of the underlying stock: If the stock price is far below or far above the striking price, the other factors have little influence. On expiration day, only the stock price and the striking price of the option determine the option's value. At this time, an option is worth only its intrinsic value.

  • Striking Price of the Option itself: The closer the strike price is to the underlying stock price, the higher the value of the option, because your chances of making money are greater than if the strike price is far from the underlying price.

    I hope that I clarified options a little better for the average investor. As you can see, options are not that complicated. Anyone with half a brain can use options to increase the value of their portfolio. Now all you have to do is read up a little more on options, and soon you'll be buying your first Ferrari.

或大跌,可以根据FA或news提前做一些准备。我在crwd和pltr宣布要加入sp 500那2个

期权的价格贵不贵,不能只看绝对值,而是要看iv和iv percentile(或iv rank),更讲究

一点还要关注iv skew。 所以我自己做了个iv percentile排行榜小工具 (

如果margin要求太高,可以卖put spread

 
 
回答: 今天比较惨 由 aloevera 于 2025-01-03 17:06:33

spread的资金利用率高很多。

例如卖下周五的410-390的put spread, 消耗margin 2000,credit  8左右。 可以用卖一个

410P的margin卖多组这样的put spreads (不过还是不要一下子卖太多,不要让可能的max

loss成为负担)。

再来看资金利用率, 如果下周五收410以上,spread 无价值过期, 相当于单周收益率 4%

(=800/2000)。 

如果下跌到390以下, max loss是1200 (当然会有后手,不会让max loss这么直接发生,

最简单的就是在合适时机往后roll, 争取net even or small debit/credit,时间换空间),

不过这时你的CC就救回来了 :)。

最近tsla IV 比较高, iv rank和iv percentile都在高位,卖有保护的期权其实还是比较划算的,

相应的卖naked就会很危险。 我现在仓位就有不少短期的short call和short put spreads,

再加一些长期leap calls。这样涨跌都高兴。

在本文中,我们将解释什么是牛市看涨价差 (spread),提供详细的示例,讨论其优点

和缺点,并回答一些常见问题。

什么是牛市看涨价差 (spread)?

牛市看涨价差 (spread)是一种期权交易策略,旨在从标的资产价格适度上涨中利润。

该策略涉及以较低的执行价格购买 看涨期权 ,同时以较高的执行价格出售另一份到

期日相同的看涨期权。主要目标是减少支付的净溢价,从而降低交易成本。

牛市价差 (spread)限制了潜在利润和潜在损失,最大利润为执行价格减去净支付的

权利金后的差额,最大损失则限制在净支付的权利金以内。

牛市看涨价差 (spread)示例

为了更好地理解牛市看涨价差 (spread)的工作原理,让我们考虑一个例子:

假设交易者认为 XYZ 公司的股票(目前交易价为 50 美元)近期将升至 60 美元。

交易者可以按如下方式实施牛市看涨价差 (spread):

  1. 购买执行价格为 50 美元的看涨期权,每股支付 5 美元的溢价。
  2. 出售看涨期权,执行价格为 60 美元,每股溢价 2 美元。

支付的净溢价为每股 3 美元(支付 5 美元 - 收到 2 美元)。由于每个期权合约通常

代表 100 股,因此支付的净溢价总额为 300 美元。

场景:

  • 股票价格上涨至 60 美元以上: 两种期权均被行使,交易者获得最大利
  • 润。最大利润为 700 美元 [(执行价差 10 美元 x 100 股)- 支付的净
  • 溢价 300 美元]。
  • 股价保持在 50 美元至 60 美元之间: 买入的看涨期权升值,而卖出的
  • 看涨期权抵消部分收益。如果股价超过 53 美元,利润将低于最大值但
  • 大于零。
  • 股票价格仍低于 50 美元: 两种期权均到期作废,交易者损失已支付
  • 的净溢价,即 300 美元。

牛市价差 (spread)的优缺点

了解牛市看涨价差 (spread)的优点和局限性可以帮助交易者决定何时使用该策略。

优点 缺点
有限风险: 潜在损失仅限于预先知道的净支付保费。

有限利润: 最高利润上限为执

行价格减去支付的净溢价之间

的差额。

成本更低: 与购买单个看涨期权相比,卖出看涨期权可降低交易的总成本。

复杂性: 比简单地买入或卖

出单一期权更复杂。

从适度上涨中利润: 允许交易者从标的资产价格适度上涨中利润。

保证金要求: 由于看涨期权

的风险,这可能需要大量的保证金。

概括

对于预期标的资产价格温和上涨的交易者来说,牛市看涨价差 (spread)是一种有用的策略。通过了

解如何实施和管理这一策略,交易者可以限制风险,同时从市场上涨中获利。将牛市看涨

价差与其他期权策略例如熊市看涨价差进行比较,有助于交易者根据其市场前景选择最合

适的策略。

常见问题解答

1. 什么是牛市看涨价差 (spread)?

牛市看涨价差 (spread)是一种期权策略,涉及以较低的执行价格买入看涨期权并以较高

的执行价格卖出另一个看涨期权,以从标的资产价格适度上涨中利润。

2. 牛市看涨价差 (spread)如何运作?

该策略要求支付净溢价来建立交易,最大利润为执行价格减去支付的净溢价之间的差额。

最大损失仅限于支付的净溢价。

3. 牛市价差 (spread)的优点和缺点是什么?

优点包括风险有限、与购买单个看涨期权相比成本较低,以及能够从适度的价格上涨中

利润。缺点包括利润有限、复杂性和潜在的保证金要求。

To buy a call option on a uptrend stock, you can:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  1. Choose a strike price and expiration date.
  2. Pay more for an in-the-money (ITM) call option if you want some intrinsic value.
  3. Buy an out-of-the-money (OTM) option for a cheaper price if you are feeling extra bullish12.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Buy stocks which are already in an uptrend to improve your performance.

 
 

Buy stocks which are already in an uptrend

Most retail investors follow the "buy low, sell higher" rule and buy a stock when its price falls. Let us carefully examine the first part - "Buy low" doesn't necessarily mean to buy a stock when its price is at a discount. Although this strategy may work in some situations, many investors incur huge losses by buying stocks in a downtrend. For example, a stock drops from $100 to $50, and you bought some shares thinking the price may not go any lower. The stock price may recover and start trending up, but what if it drops to $40? Do you buy more shares and average down? What if the stock price further plummets to $20? No matter how good a company is, its stock price can still go lower. Stock market history provides many instances where stocks of once great companies went to Zero, and averaging down will wipe out your capital.

Imagine you are running a fashion boutique with ten green and ten red dresses in the store. For whatever reason, consumers are eagerly buying red dresses compared to green ones. Now, if you want to re-stock your store, which dresses would you order more - green or red? The red ones, because they are in huge demand and selling out quickly. And what happens to the existing green dresses in the store? - you would offer a discount to sell out the low-demand merchandise to make space for the ones in high demand(red). Similar to the fashion boutique situation, as a stock trader, the goal is to buy stocks having high demand and sell them for a higher price to book profits. But, the price of a product with high demand will never go from $100 to $50. Instead, it will be trending upwards to greater than $100. That's why you don't buy stocks in a price downtrend. A downtrend implies lower demand. Change your mindset to follow the "buy high, sell higher" rule. Buy high means looking for stocks that are in an uptrend.

If you avoid buying/averaging down stocks in decline and only purchase stocks which are in uptrend, your results will improve significantly.

Hope this helps someone and let me know if you have any questions or doubts about this.

所谓操作级别,实质上包含着二层含义,一是时间周期,二是走势空间。 时间同期是指操作的时间,如1分、5分、30、一小时、四小时、日线、周线等等;走势空间是指该时间周期行情走势的一笔。 如30分周期的一笔走势就是该周期的操作级别。 明白了操作级别的概念后,在实战交易过程中,如果你是做30分操作级别的,那么出现五分级别的回调,你是不应该轻易平仓的,而是等待走完30分钟一笔,即五分走势类型出现背驰,才会平仓。 假如五分钟走势类型没有背驰,那么,表明30分一笔没有结束,等待五分钟最终出现背驰终结。 如果你是做五分钟级别的,那么当五分钟一笔结束就应该平仓了结。

 

 

生于安逸,死于忧患

 
 

忧愁的人早死,快乐的人晚死。因此“生于安逸,死于忧患”。不能在此刻快乐的人,

其实并不矛盾。与世界打交道用正逻辑。根据客观世界的规律,有可能要对一些事情未雨

绸缪,提前防备。如果忽略了,将被自然规律惩罚。例如忽略即将倒塌的房屋,漏水的
