There are several popular options strategies frequently discussed in the trading and investing literature, as well as on social media. In a previous post, we examined the effectiveness of the covered call strategy, which has gained wide adoption among retail investors. In this edition, we extend our critical evaluation to another widely used approach—the options collar, a strategy employed by both retail traders and institutional investors.
 

Assessing the Effectiveness of Zero-Cost Collar in Different Markets

The zero-cost collar strategy is an options trading strategy that involves the simultaneous purchase of a put option and the sale of a call option. The options are usually of the same maturity, and the transaction results in a zero or small credit to the trader’s account.

This strategy is often used by investors who are bullish on a stock but want to protect themselves against a potential drop in the price. By buying the put option, they have the right to sell the stock at a predetermined price (the strike price). If the stock price falls below the strike price, they can sell the stock and offset any losses.

The sale of the call option helps to offset the cost of the put option and results in a zero or small credit to the trader’s account. This strategy is sometimes referred to as a “zero cost” collar because the net cost of the trade is zero.

Reference [1] examined the effectiveness of the zero-cost collar strategy in the developed and developing markets.
 

Findings

-The paper’s objective is to provide investors with a continuously implemented trading strategy that can effectively handle turbulent market periods such as the Dotcom bubble, the 2008–2009 financial crisis, and the COVID-19 pandemic.

-The study analyzes stock indices from six countries across both developed and developing economies to assess how extreme market events affect performance.

-Zero-cost collars are proposed as a costless option-based protection strategy, created by equating the cost of the long and short option components.

-Prior literature has not evaluated zero-cost collars across different rebalancing frequencies or tested their outcomes in both turbulent and stable markets.

-Results show that zero-cost collars generate strong returns when market volatility is moderate, and the underlying indices perform well, especially when the put strike is set at a higher level.

-The strategy performs respectably during severe downturns as well as during trending or declining markets.

– Its effectiveness depends on market conditions and the choice of strike levels.

Overall, the paper contributes a practical trading strategy that helps investors manage turbulent market conditions through the continuous application of zero-cost collars.

How the Airlines Hedge Fuel Costs

The recent rise in the cost of airline tickets can be attributed in part to the escalating fuel prices, which significantly affect operating expenses for airlines. To counter the adverse impact of fuel price volatility, airlines often adopt a strategic approach known as fuel hedging. This practice involves entering into financial contracts to secure future fuel purchases at predetermined prices, mitigating the vulnerability to sudden spikes in fuel costs. Fuel hedging provides airlines with a degree of price certainty, offering a measure of stability in budgeting and operational planning while allowing them to better manage the economic challenges posed by fluctuating fuel prices.

Amongst the US airlines, Southwest Airlines distinguishes itself for its efficient execution of the hedging strategy. It has maintained a record of profitability since 1973, an accomplishment that sets it apart in the US airline sector. Expert observers attribute Southwest’s sustained financial success to its proficient utilization of derivatives for the purposes of hedging. An analysis of Southwest Airlines’ financial statements across multiple years reveals a distinct trend: the share of jet fuel expenses is consistently lower compared to the industry norm. This achievement can be directly attributed to the precise implementation of their jet fuel hedging strategy, a practice that effectively shields the airline from fluctuations in fuel prices.

Reference [2] examined the fuel hedging strategy of Southwest Airlines in detail.
 

Findings

-The paper analyzes why hedging jet fuel is critical for airlines, given the high volatility of oil prices, and highlights how Southwest Airlines’ long-term low-cost strategy is closely tied to its effective fuel-hedging program.

-It examines Southwest’s financial background and stock performance as a foundation for evaluating its hedging approach.

-The study identifies four key hedging strategies used by Southwest Airlines: call options, collar structures, call spreads, and put spreads.

-By combining these four strategies, Southwest effectively mitigated jet-fuel price risk without engaging in speculative derivative positions.

-A comparison with other airlines shows that Southwest’s disciplined, non-speculative approach contributed significantly to its hedging success and cost stability.

-The paper also evaluates how COVID-19 and oil-price movements related to production-cut agreements adversely affected Southwest, leading to over-hedging and substantial losses in 2020.

In short, the paper discussed the intricacies of Southwest Airlines’ hedging strategies and demonstrated their value-added effect. It is apparent that the deployment of hedging by Southwest Airlines yields advantages. However, it is important to underscore the necessity of a well-designed hedging program, one that avoids the potential pitfall of over-hedging.

Closing Thoughts

Taken together, the two studies illustrate how collar-based strategies can play an important role in managing volatile market conditions, whether for broad equity portfolios or for highly fuel-sensitive industries such as airlines. The first study shows that zero-cost collars can deliver respectable risk-adjusted outcomes during major market disruptions, particularly when volatility is moderate, and strike selection is calibrated appropriately. The second study highlights how Southwest Airlines effectively applied options structures, including collars, to hedge jet-fuel exposure, while also underscoring the risks of over-hedging during periods such as COVID-19. Collectively, the evidence reinforces that collar strategies can be valuable risk-management tools, but their effectiveness depends critically on market regime, implementation frequency, and disciplined design.
