خيارات الأسهم: دليل مبتدئ لتداول الحقوق
خيارات الأسهم هي أدوات مالية تمنح صاحبها الحق، وليس الالتزام، بشراء أو بيع سهم أساسي (عادةً أسهم شركة) بسعر محدد مسبقًا في أو قبل تاريخ محدد. هذا الحق، على عكس الالتزام المتأصل في عقد العقود الآجلة، يوفر مرونة وقوة رافعة محتملة، ولكنه يحمل أيضًا مخاطر كبيرة. إن فهم هذه الأدوات أمر بالغ الأهمية لأي شخص يفكر في إضافتها إلى محفظة استثماراته.
أساسيات خيارات الأسهم:
يمثل عقد خيار الأسهم عقدًا بين طرفين: المشتري (صاحب الخيار) والبائع (كاتب الخيار). هناك نوعان رئيسيان من الخيارات:
خيارات الشراء (Call Options): تمنح المشتري الحق، وليس الالتزام، بشراء السهم الأساسي بسعر محدد (سعر الإضراب) في أو قبل تاريخ محدد (تاريخ انتهاء الصلاحية). يكسب المشتري إذا ارتفع سعر السهم فوق سعر الإضراب قبل انتهاء الصلاحية. يكسب البائع إذا ظل سعر السهم دون سعر الإضراب حتى انتهاء الصلاحية.
خيارات البيع (Put Options): تمنح المشتري الحق، وليس الالتزام، ببيع السهم الأساسي بسعر محدد (سعر الإضراب) في أو قبل تاريخ محدد (تاريخ انتهاء الصلاحية). يكسب المشتري إذا انخفض سعر السهم دون سعر الإضراب قبل انتهاء الصلاحية. يكسب البائع إذا ظل سعر السهم فوق سعر الإضراب حتى انتهاء الصلاحية.
المصطلحات الرئيسية:
إن فهم المصطلحات التالية أمر بالغ الأهمية لفهم خيارات الأسهم:
- سعر الإضراب (Strike Price): السعر الذي يمكن لصاحب الخيار أن يشتري به (خيار الشراء) أو يبيع به (خيار البيع) السهم الأساسي.
- تاريخ انتهاء الصلاحية (Expiration Date): آخر يوم يمكن فيه ممارسة الخيار.
- الأجرة (Premium): السعر الذي يدفعه المشتري للحصول على عقد الخيار. هذه هي تكلفة الحق، وليس تكلفة السهم الأساسي نفسه.
- في السوق (In-the-money): يكون الخيار في السوق عندما يؤدي ممارسته إلى تحقيق ربح على الفور. بالنسبة لخيار الشراء، هذا يعني أن سعر السوق للسهم الأساسي أعلى من سعر الإضراب. بالنسبة لخيار البيع، هذا يعني أن سعر السوق أقل من سعر الإضراب.
- خارج السوق (Out-of-the-money): يكون الخيار خارج السوق عندما يؤدي ممارسته إلى خسارة فورية.
- في سعر السوق (At-the-money): يكون الخيار في سعر السوق عندما يكون سعر السوق للسهم الأساسي مساويًا لسعر الإضراب.
لماذا تداول خيارات الأسهم؟
توفر الخيارات العديد من المزايا:
- الرافعة المالية (Leverage): تسمح الخيارات للمستثمرين بالتحكم في مركز أكبر في السهم الأساسي برأس مال أصغر مقارنة بشراء الأسهم مباشرة.
- التحوط (Hedging): يمكن استخدام الخيارات لحماية ضد الخسائر المحتملة في مركز أسهم موجود. على سبيل المثال، يمكن أن يعمل خيار البيع كنوع من التأمين ضد انخفاض قيمة السهم الذي تملكه.
- توليد الدخل (Income Generation): يمكن أن يؤدي بيع الخيارات (كتابة خيارات الشراء المغطاة أو خيارات البيع المضمونة نقدًا) إلى توليد الدخل. ومع ذلك، فإن هذه الاستراتيجية تحمل مخاطر كبيرة إذا تحرك السهم الأساسي ضد مركز البائع.
- المضاربة (Speculation): يمكن استخدام الخيارات للمضاربة على اتجاه السوق.
مخاطر تداول خيارات الأسهم:
يحمل تداول الخيارات مخاطر كبيرة:
- انخفاض القيمة مع مرور الوقت (Time Decay): تنخفض قيمة الخيار مع اقتراب تاريخ انتهاء صلاحيته، حتى لو ظل سعر السهم الأساسي دون تغيير.
- إمكانية ربح محدودة (للمشترين): بينما تكون إمكانية الربح غير محدودة نظريًا بالنسبة لمشتري خيارات الشراء في سوق صاعدة ومشتري خيارات البيع في سوق هابطة، إلا أن أقصى خسارة تقتصر على الأجرة المدفوعة.
- إمكانية خسارة غير محدودة (للبائعين): الخسارة المحتملة للبائع غير محدودة نظريًا للمراكز غير المغطاة (بيع خيارات الشراء أو البيع بدون امتلاك السهم الأساسي أو ما يكفي من النقد لشرائه).
الخاتمة:
خيارات الأسهم أدوات قوية للمستثمرين المتمرسين، حيث توفر مرونة ورافعة مالية. ومع ذلك، فإن تعقيدها ومخاطرها المتأصلة تتطلب فهمًا دقيقًا قبل الانخراط في التداول. من المهم إجراء بحث شامل، والنظر في تحملك للمخاطر، وربما طلب المشورة المالية المهنية قبل دمج الخيارات في استراتيجيتك الاستثمارية. بينما توفر هذه المقالة نظرة عامة أساسية، فإن الدراسة الإضافية ضرورية لأي شخص يتطلع إلى التنقل في تعقيدات سوق الخيارات.

Scenario: You own 100 shares of XYZ Corp. stock, currently trading at $50 per share. You are concerned about a potential market downturn and want to protect your investment. You consider buying put options with a strike price of $45 and an expiration date one month from now. The premium for each put option contract (covering 100 shares) is $200.
Tasks:
- Describe how buying these put options would act as a hedge against a decline in XYZ Corp.'s stock price.
- Calculate your maximum loss and maximum profit if you buy these put options.
- What would be your overall profit or loss (including the cost of the put options) if the price of XYZ Corp. stock drops to $40 per share at expiration?
Exercice Correction
1. Hedging: Buying put options acts as insurance. If the stock price falls below $45 before expiration, you can exercise your put options, selling your 100 shares at $45 each, limiting your losses. Without the puts, you'd be forced to sell at the lower market price.
2. Maximum Loss and Profit:
- Maximum Loss: The maximum loss is the total premium paid, which is $200. This is because even if the stock price goes to zero, you are only out the cost of the option contracts.
- Maximum Profit: Your maximum profit would be limited by the difference between the strike price ($45) and the premium paid ($200/$100 shares = $2 per share). If the stock drops to $0, you could exercise your options and sell at $45 but would net $43 per share after paying the premium ($45 - $2). For 100 shares, your profit would be $4300.
3. Profit/Loss at $40 Stock Price:
If the stock drops to $40, you would exercise your put options and sell your 100 shares at $45. Your profit from selling the shares would be ($45 - $40) * 100 = $500. However, you paid $200 in premiums, so your net profit would be $500 - $200 = $300.

Techniques
Unpacking Equity Options: A Beginner's Guide to Trading Rights
Chapter 1: Techniques
This chapter delves into the various techniques employed when trading equity options. We'll explore both buying and selling strategies, highlighting their respective risks and rewards.
Buying Options:
- Buying Call Options: This bullish strategy profits when the underlying stock price rises above the strike price before expiration. We'll discuss different scenarios, including early exercise and assignment.
- Buying Put Options: This bearish strategy profits when the underlying stock price falls below the strike price before expiration. We will analyze various market conditions impacting this strategy.
- Option Spreads: This involves simultaneously buying and selling options contracts to define risk and profit parameters. We will examine various spread strategies, such as bull call spreads, bear put spreads, iron condors, and straddles, detailing their mechanics and risk profiles.
- Option Combinations: These strategies involve combining multiple options contracts of different types (calls and puts) and strikes to create complex trading positions with specific risk-reward profiles.
Selling Options (Writing Options):
- Writing Covered Calls: This involves selling call options on stock you already own, generating income but limiting potential upside. We will examine the risks and benefits of this strategy, including early assignment.
- Writing Cash-Secured Puts: This involves selling put options, requiring the seller to have enough cash to buy the underlying stock if the option is exercised. We'll analyze the break-even points and risk/reward profiles.
- Naked Options: This is a high-risk strategy involving selling options without owning the underlying asset or sufficient cash to cover potential losses. We will emphasize the significant risks involved and strongly caution against this approach for inexperienced traders.
