Core Viewpoint - The article introduces the Long Butterfly Spread options strategy, which serves as a "price range insurance" for investors expecting a stock to remain stable within a certain price range, allowing for limited risk and potentially high returns [1][3]. Strategy Composition - The strategy involves trading three options: buying one lower strike Call (X1), buying one higher strike Call (X3), and selling two middle strike Calls (X2), with the relationship X2 = (X1 + X3)/2 [1][2]. - The initial net premium paid is calculated as C1 + C3 - 2 × C2, where C1, C2, and C3 are the premiums for the respective options [1][5]. Investment Significance - The core of the strategy is to have the underlying asset's price remain close to the middle strike price (X2) before the options expire, with minimal volatility [3]. - It combines elements of both Bull Call Spread and Bear Call Spread, making it a neutral strategy that profits in sideways markets [3]. Profit and Loss Characteristics - Maximum profit occurs when the stock price equals the middle strike price (X2), while maximum loss is limited to the initial net premium paid [6][8]. - The strategy is characterized by a small risk of loss, with profits increasing as the stock price approaches the middle strike price [6][10]. Practical Application Example - An example is provided where an investor believes a stock priced at $633 will remain stable around $635. The investor sets up a Long Butterfly Spread by buying Calls at $630 and $640, and selling Calls at $635, resulting in a maximum loss of $25 and a maximum profit of $475 [7][8]. Recommendations for Use - The strategy is best suited for short to medium-term contracts (20-30 days until expiration) and should be executed when implied volatility is high [10][11]. - Investors are advised to avoid holding positions until expiration to mitigate risks associated with significant price movements [12]. Conclusion - The Long Butterfly Spread is a low-risk strategy ideal for investors seeking to profit from minimal price fluctuations in stable markets, particularly when volatility is expected to decrease [6][10].

Core Viewpoint - The article introduces the Short Bear Ratio Spread strategy, which allows investors to bet on a significant decline in stock prices with very low or even zero initial costs while effectively hedging against unlimited losses from potential price increases [1]. Strategy Composition - The strategy involves buying a larger number of at-the-money (ATM) or slightly out-of-the-money (OTM) put options while selling a smaller number of in-the-money (ITM) put options, all with the same expiration date [1]. - The main investment rationale is to maintain a bearish outlook on the stock while controlling entry costs and hedging against unlimited losses from price increases [1]. Comparison with Other Strategies - Compared to simply buying put options, this strategy avoids high premium costs and can potentially allow for "free entry" into bearish positions [4]. - In contrast to merely selling put options, the purchased puts provide profit during stock declines, mitigating losses during significant downturns [4]. Profit and Loss Characteristics - The strategy aims to minimize initial premium costs by offsetting the cost of buying puts with the income from selling higher strike ITM puts, potentially achieving zero or negative initial costs [5]. - The maximum loss occurs when the stock price equals the strike price of the bought puts, while the maximum profit is limited to the stock price dropping to zero [6][7]. Strategy Features 1. Low entry cost: The strategy can achieve near-zero or negative costs, providing an opportunity to participate in downward trends almost for free [7]. 2. Ability to capture profits during significant declines while limiting losses during price increases [7]. 3. Complexity in determining the appropriate strike prices and ratios, making it suitable for experienced options investors [7]. Practical Application Scenarios - Example 1: A 2:1 ratio involves buying 2 puts with a strike price of 390 and selling 1 put with a strike price of 470, resulting in an initial premium expenditure of $760, which is approximately 86% less than simply buying puts [9]. - Example 2: A 3:2 ratio involves buying 3 puts with a strike price of 390 and selling 2 puts with a strike price of 430, leading to an initial premium expenditure of $555 [14]. - Example 3: A 3:1 ratio involves buying 3 puts with a strike price of 380 and selling 1 put with a strike price of 520, with an initial premium expenditure of $1,080 [18]. Recommendations - Prioritize long-term contracts (6-12 months) for stocks expected to reverse trends, as they provide more time for the trend to materialize and have slower time decay [24]. - Suitable for stocks with high volatility expectations, where significant price movements are anticipated [24]. - If the stock price remains stagnant, consider closing the position early to avoid being assigned on sold options [24].
