Dans le monde dynamique des marchés financiers, l'incertitude règne en maître. Les mouvements de prix sont souvent dictés par un ensemble de facteurs, rendant les prédictions précises difficiles. C'est là qu'intervient le concept de stratégie « dans les deux cas », souvent lié au trading d'options et à d'autres instruments dérivés. Essentiellement, une approche « dans les deux cas » vise à réaliser un profit que le prix de l'actif sous-jacent monte ou baisse, capitalisant sur la volatilité plutôt que sur une certitude directionnelle.
Comprendre les stratégies « dans les deux cas » :
Une stratégie « dans les deux cas » ne consiste pas à prédire la direction d'un mouvement de prix, mais plutôt à parier sur l'ampleur du mouvement. Ceci est réalisé grâce à diverses techniques, notamment :
Straddles et Strangles : Ces stratégies d'options impliquent l'achat simultané d'une option d'achat et d'une option de vente avec le même prix d'exercice (straddle) ou des prix d'exercice différents (strangle). Le profit est maximisé lorsque le prix de l'actif sous-jacent évolue significativement dans l'un ou l'autre sens, dépassant le coût combiné des options. Plus l'amplitude du mouvement des prix est importante, plus le profit potentiel est élevé. Inversement, si le prix reste relativement stable autour du prix d'exercice, l'investisseur perd la totalité de la prime payée pour les options.
Stratégies Collar : Ces stratégies consistent à détenir l'actif sous-jacent et à acheter simultanément une option de vente (protection contre le risque baissier) et à vendre une option d'achat (génération de revenus). Cela limite les gains potentiels à la hausse, mais protège contre des pertes importantes. C'est une approche « dans les deux cas » en ce sens qu'elle profite d'une stabilité modérée des prix ou d'une baisse limitée, tout en atténuant les mouvements importants à la hausse.
Trading de la volatilité : Certains investisseurs se concentrent sur le trading de la volatilité elle-même, souvent en utilisant des indices de volatilité comme le VIX. Ils peuvent tirer profit des augmentations de volatilité, que le marché sous-jacent monte ou baisse. Il s'agit d'une approche plus sophistiquée qui nécessite une compréhension approfondie de la dynamique de la volatilité et de la gestion des risques.
Prix de seuil et sa relation avec les stratégies « dans les deux cas » :
Le « prix de seuil », parfois appelé « prix de rentabilité », est un élément crucial pour comprendre la rentabilité d'une stratégie « dans les deux cas ». Il représente le niveau de prix auquel la stratégie devient rentable. Pour un straddle, le prix de seuil est le prix d'exercice plus la prime totale payée. Pour un strangle, le calcul du prix de seuil est plus complexe, variant en fonction des prix d'exercice des options d'achat et de vente.
La distance entre le prix de seuil et le prix actuel du marché indique le potentiel de profit. Une distance plus grande suggère des gains potentiels plus importants, mais implique également un risque plus élevé, car le prix doit bouger significativement pour atteindre la rentabilité.
Risques associés aux stratégies « dans les deux cas » :
Bien que les stratégies « dans les deux cas » puissent être lucratives, elles comportent des risques importants :
Erosion temporelle : Les options perdent de la valeur à mesure que leur date d'expiration approche (érosion temporelle). Cela peut réduire considérablement la rentabilité si l'actif sous-jacent ne bouge pas suffisamment.
Risque illimité (dans certains cas) : Certaines stratégies, comme les straddles et les strangles longs, peuvent entraîner des pertes illimitées si le prix de l'actif sous-jacent évolue considérablement contre la position de l'investisseur.
Primes élevées : L'achat d'options implique le paiement d'une prime initiale, ce qui peut réduire les profits si le marché ne bouge pas substantiellement.
Résumé :
Les stratégies « dans les deux cas » sur les marchés financiers permettent de capitaliser sur la volatilité des prix plutôt que de prédire les mouvements directionnels. Elles offrent un potentiel de profits importants, mais comportent également des risques substantiels. Comprendre les mécanismes des différentes stratégies, y compris le prix de seuil et l'impact de l'érosion temporelle, est crucial pour une mise en œuvre réussie. Ces stratégies sont mieux adaptées aux investisseurs expérimentés ayant une solide compréhension du trading d'options et de la gestion des risques.

(b) Reduced potential for profit as options expire.
4. The "choice price" (or breakeven price) in an "either way" strategy represents: (a) The price at which the investor begins to lose money. (b) The price at which the investor starts making a profit. (c) The average price of the underlying asset over a given period. (d) The predicted future price of the underlying asset.
(b) The price at which the investor starts making a profit.
5. Which of the following is NOT typically considered an "either way" strategy? (a) Straddle (b) Strangle (c) Buying only call options (d) Volatility trading
(c) Buying only call options
Scenario: You are considering a straddle strategy on XYZ stock, which is currently trading at $100. You buy a call option with a strike price of $100 and a put option with a strike price of $100. The premium for each option is $5.
Task:
1. Choice Price Calculation:
The total premium paid for the straddle is $5 (call) + $5 (put) = $10.
The choice price (breakeven price) for a straddle is the strike price plus the total premium. Therefore, the choice price is $100 + $10 = $110.
2. Profit/Loss at Expiration:
3. Risks and Rewards:
Rewards: The potential for profit is unlimited if the price moves significantly above or below the choice price. This strategy benefits from high volatility in the underlying asset.
Risks: The maximum loss is limited to the total premium paid ($10 per share). However, if the price remains close to the strike price at expiration, the entire premium is lost. Time decay will also erode the value of the options as their expiration date approaches. This strategy is highly sensitive to volatility, making it riskier for those inexperienced in options trading.

This chapter details the specific methods employed in "either way" strategies, focusing on the mechanics of each approach and its underlying principles.
Straddles and Strangles: The core of these strategies lies in simultaneously purchasing both call and put options on the same underlying asset. A straddle uses options with identical strike prices, while a strangle employs options with different strike prices (typically, the put option has a lower strike price than the call). Profitability hinges on significant price movement in either direction, exceeding the total premium paid. The further the price moves from the strike price(s), the greater the profit. Conversely, if the price remains stable near the strike price(s), the entire premium is lost. The calculation of the breakeven point involves adding the premium paid to the strike price for a straddle; strangles require a more nuanced calculation based on both strike prices and premiums.
Collar Strategies: Unlike straddles and strangles which are purely options-based, collar strategies involve the underlying asset itself. An investor who already owns the asset can buy a put option to protect against downside risk and simultaneously sell a call option to generate income. This approach limits potential upside gains but safeguards against significant losses. Profitability stems from moderate price stability or limited downside movements, with larger upward movements being capped by the sold call option.
Volatility Trading: This approach doesn't directly bet on price direction but on the magnitude of price fluctuations – volatility. Traders often utilize volatility indexes (e.g., VIX) as instruments, profiting from increased volatility regardless of the market's upward or downward trend. This strategy requires a sophisticated understanding of volatility dynamics and employs complex risk management techniques. It often involves the use of options or other derivatives whose price is directly linked to the volatility index.
Chapter 2: Models
This chapter explores the mathematical models used to evaluate and predict the potential outcomes of "either way" strategies.
Option Pricing Models: Models like the Black-Scholes model are fundamental in calculating the theoretical price of options, which are crucial components of many "either way" strategies. Understanding these models is vital for assessing the fairness of option prices and determining the potential profitability of a strategy. These models consider factors like the underlying asset's price, volatility, time to expiration, interest rates, and dividend yield.
Monte Carlo Simulation: This probabilistic model can simulate numerous potential price scenarios for the underlying asset, allowing for the estimation of the probability distribution of potential profits and losses from an "either way" strategy. This provides a more comprehensive risk assessment compared to relying solely on theoretical option pricing models.
Stochastic Volatility Models: These models acknowledge that volatility itself is not constant but fluctuates over time. They are particularly relevant for volatility trading strategies, offering a more realistic representation of market dynamics than models assuming constant volatility.
Chapter 3: Software
This chapter examines the software tools and platforms utilized for implementing and managing "either way" strategies.
Trading Platforms: Most brokerage platforms offer the tools necessary for executing options trades, including placing orders, monitoring positions, and analyzing market data. Features such as option chains, profit/loss calculators, and real-time charting are essential. Some platforms provide sophisticated analytical tools specifically designed for options trading.
Spreadsheets and Programming Languages: Spreadsheets like Excel or Google Sheets can be used for calculating option prices, analyzing potential profits and losses, and backtesting strategies. Programming languages like Python, with libraries such as QuantLib or PyOption, allow for more complex modeling and backtesting of "either way" strategies.
Data Analytics Tools: Access to reliable market data is crucial. Software and services providing historical and real-time market data, as well as volatility indices, are necessary for informed decision-making and strategy development.
Chapter 4: Best Practices
This chapter highlights essential considerations for effectively utilizing "either way" strategies, emphasizing risk management and responsible trading.
Risk Management: Thorough risk assessment is paramount. Defining acceptable risk levels, setting stop-loss orders, and diversifying across multiple assets are crucial for mitigating potential losses. Understanding the unlimited loss potential of some strategies (like unhedged long straddles) is critical.
Position Sizing: Properly sizing positions relative to overall capital is vital. Over-leveraging can lead to significant losses if the market moves unfavorably.
Time Decay Management: Awareness of time decay is crucial. Strategies with shorter time horizons should be chosen carefully and managed proactively.
Understanding Market Conditions: "Either Way" strategies perform differently in various market environments. Understanding the prevailing market sentiment, volatility levels, and implied volatility can greatly influence the effectiveness of the chosen strategy.
Chapter 5: Case Studies
This chapter presents real-world examples illustrating the application and outcomes of "either way" strategies under diverse market conditions.
Case Study 1: A successful strangle during a period of high implied volatility. This case study would describe a scenario where a strangle strategy generated significant profits due to a large price swing in the underlying asset, despite uncertainty regarding the direction of the swing. Key factors such as the selection of strike prices, the timing of the trade, and the market conditions would be discussed.
Case Study 2: A less successful straddle during a period of low volatility. This case study would illustrate a situation where a straddle strategy resulted in losses due to the lack of significant price movement in the underlying asset. The analysis would examine why the strategy failed, focusing on the impact of time decay and the relatively high premium paid.
Case Study 3: Employing a collar strategy to protect a long position during market uncertainty. This example would showcase how a collar strategy was used to limit downside risk while maintaining some upside potential during a period of market volatility. The effectiveness of the strategy in mitigating losses while forgoing some profit would be assessed.
These case studies would highlight both the potential successes and failures of "either way" strategies, providing practical insights into their implementation and limitations. They would emphasize the importance of thorough risk management and a deep understanding of market dynamics for successful application.
