The enhanced collar - Immediate portfolio protection with upside potential

Peter Siks

Summary:  With a normal collar you can lower your risk or lock in a profit. This option combination exists of long stock, a long put (right to sell) and a short call (potential obligation to deliver). Maximum profit and loss are known upfront. But there is even a smarter way to apply the concept of the collar. In this article is explained how.

The basic collar

Owning stock always bears the risk of declining prices. Is it possible to protect you from this? With options it is possible; the simplest way to achieve that would be buying a put option as protection for your individual stock position. Disadvantage is the (insurance) premium you have to pay. A way to decrease the investment is by selling a call at the same time. This limits the upside potential but does makes the initial investment of the protection lower. But is there a better way? Yes, there is, because you can apply the old saying: “Buy low, sell high” in a smarter way.

The enhanced (intelligent) collar

If you would compare the volatility level of an individual stock versus an index, in almost all cases the volatility of the individual stocks will be higher than that of the index. This means that the options premiums on the individual stocks are higher than in the index. So, how would it be if you sell the ‘expensive’ options (the calls on the individual shares) and at the same time buy the ‘cheap’ option (the puts on the index)?

If you have a portfolio consisting of several individual stocks, it is worthwhile to consider the following construction. Sell calls on the individual stocks and buy protection via puts on an index level. In other words, the basic concept of the collar applied in an intelligent way.

In that way you create still some upside potential in the individual stocks and at the same time you have created a portfolio insurance that protects your portfolio from the current level. It could easily be that the upside potential is 8% - 10% in the individual shares and the downside is 0% - 1% on a portfolio level.

An example with a portfolio consisting of 8 individual stocks (closing prices of Friday October 6 are used).

Close October 6thCall strikeUpside potentialPremium received Dec ’23 callPremium as % of stock price

In the table above you will find big differences in the premium received for a 10% OTM call. It is all depending on the volatility of the underlying. But on average in this example it is 2,8%.

The S&P500 index is the one for buying downside protection. The normal S&P500 index options are ‘heavy’ options with an index around 4,300 and a contract size of 100. Therefor the options on the mini S&P500 will be used. This index trades at 1/10th of the price of the S&P500 index. The ticker to find these – cash settled – options is XSP.

The S&P500 index closed Friday the 6th of October at 4,308.50, so the 431 strike is the ATM put to buy if you want immediate protection. It traded at $10.20 at the close and that is 2.4% of the underlying.

By applying this strategy at these prices you have constructed downside protection that immediately starts working if the market declines. In case the stock market advances, there is 10% upside potential before you have to deliver the underlying as a result of the short call.

When to apply an enhanced collar?

There are times where you might be not sure about the current market level. The view is not strong enough to liquidate your whole portfolio right away, but some protection would be very welcome. The use of the enhanced collar could be a solution.

There are some things that you have to take into consideration when you apply this strategy:

  • First of all, it must be in line with your view on the market. If you are bullish, limiting your upside potential (as a result of the short calls) does not fit. In other words: do not apply this strategy.
  • Second, the portfolio must be large enough because the insurance you buy with the index put is relatively big. For the S&P500-index, trading at the level of 4,310, the XSP 431 P insures a portfolio of $43,100. (100 * strike).
  • The portfolio must be very well correlated with the index. Otherwise you might end up in the situation where your portfolio is declining in value and the index is rising. So, you lose money on both.
  • The portfolio must be (very) well diversified, otherwise the situation can occur where an individual holding goes South without any movement in the index.
  • It assumes you do not have written calls yet on your holdings.
  • You are familiar with the characteristics of options and able to assess both the upside as downside of this strategy.

What is the ideal scenario?

The most ideal scenario would be a slightly rising market. The stocks in your portfolio increase in value without the need to deliver any of them (due to the short call). A neutral scenario would be a market moving sideways where all the options expire worthless.

What is a nasty scenario?

If a few of your (bigger) individual holdings will get hammered without causing any effect on an index level. As a result your portfolio will decrease in value and this is not offset by the long index puts.

What is your max loss?

In this construction this is hard to say because of the scenario where a few of your individual holdings are sharply decreasing in value. But on a portfolio level, the maximum loss is very limited because the insurance you bought immediately kicks in when the overall market declines.

In short

An enhanced collar is not the simplest of option strategies. But the concept of ‘Sell high, buy low’ is applied in a clever way with this approach. Furthermore, this strategy is not applicable to all portfolios. The portfolio must be large enough, very well correlated to the corresponding index and very well diversified. But the end result is appealing: portfolio protection on the current index level and upside potential in the individual stocks.
