Collar

A Collar (also known as a 'protective collar') is an options strategy designed to protect an investor's gains in a stock they already own. Think of it as building a 'fence' around your stock's price. You establish a price floor below which your investment can't fall, but in exchange, you also set a price ceiling above which your profits can't rise. This is achieved by simultaneously buying a put option (your insurance against a price drop) and selling a call option (which pays for the insurance but caps your upside). For an investor who has enjoyed a significant run-up in a stock but is nervous about a potential short-term pullback, a collar can be a low-cost way to sleep better at night. It effectively locks in a range of potential outcomes, protecting capital from a major downturn while sacrificing potential windfall profits.

The Gist of a Collar

At its core, a collar is a three-legged position you build around a stock you own (the underlying asset):

The magic happens when the premium you receive from selling the call mostly or entirely covers the premium you paid for the put. When the costs are equal, it's called a zero-cost collar. You've essentially gotten downside protection for free, with the only “cost” being the limit on your future profits.

How a Collar Works: A Nuts-and-Bolts Example

Let's say you bought 100 shares of a fictional company, “Value Vistas Inc.” (VVI), at $50 per share, and it has since soared to $100 per share. You're sitting on a nice $5,000 gain, but you think the market might get rocky. You don't want to sell and pay capital gains tax, but you also don't want to lose your hard-earned profit. You decide to put on a collar:

  1. You buy one VVI put option with a strike price of $90, expiring in three months. This gives you the right to sell your 100 shares for $90 each, no matter what. Let's say this insurance costs you a premium of $2 per share, or $200 total (100 shares x $2).
  2. You sell one VVI call option with a strike price of $110, expiring in the same three months. This obligates you to sell your shares for $110 if the buyer chooses. For taking on this obligation, you receive a premium of $2 per share, or $200 total (100 shares x $2).

In this scenario, you've created a zero-cost collar. Now let's see what happens when the options expire:

The Value Investor's Take on Collars

A strict value investing purist might argue that if you've bought a wonderful business at a fair price, you should simply hold it through thick and thin, ignoring market fluctuations. However, a more pragmatic value investor might see a collar as a sensible risk-management tool in specific circumstances. It's not for speculation. Rather, a value investor might use a collar when:

While useful, collars are not without their downsides.
