Split-Strike Conversion

A Split-Strike Conversion (also known as a 'Collar' or 'Risk Reversal') is an options strategy designed to protect a stock holding from downside risk. Think of it as putting a “collar” on your investment: you set a floor below which you can't lose much more, and a ceiling above which you can't gain any more. It is created by an investor who already owns an underlying stock (a long position) and then simultaneously buys a protective put option and sells a call option on that same stock. The key is that the two options have different strike prices—hence, “split-strike.” The goal is often to structure the trade so that the money received from selling the call option covers the cost of buying the put option, creating a “zero-cost collar” and providing downside protection for free, in exchange for giving up some potential upside.

How Does It Work? A Practical Example

Imagine you're a value investor who bought 100 shares of a solid company, “SteadyShip Inc.,” at $75 per share. The stock has done well and is now trading at $100. You still believe in the company long-term, but you're worried about a potential market correction and want to protect your hard-earned gains without selling the stock. Here's how you could set up a split-strike conversion:

In this perfect scenario, the $200 you received from selling the call perfectly offsets the $200 you paid for the put. You've created a zero-cost collar. Now, your position is “collared” between $90 and $110 until the options expire.

The Investor's Takeaway: Why Bother?

From a value investing perspective, this isn't a tool for speculation but for prudent risk management on a position you already hold and understand. It's an advanced technique, but it has its place.

For the Cautious Value Investor

The Downsides and Dangers

Is It for You?

A split-strike conversion is not for beginners. It's a strategic tool best suited for investors who:

  1. Hold a stock that has seen significant appreciation.
  2. Want to protect those gains from short-to-medium-term market volatility.
  3. Are willing to sacrifice further upside potential in exchange for that protection.
  4. Understand the mechanics of options or are willing to learn them thoroughly.

Ultimately, it's a way to manage risk on a winning position. It’s not a substitute for sound, fundamental analysis but rather a supplement to it, helping a value investor sleep a little better at night when markets feel uncertain.
