Editor’s note: This article was published in the MTA Journal in 1980 and looked at exchange-traded options trading less than ten years after they were introduced. A full copy of that Journal is available at http://go.mta.org/3149.
Bernadette M. Murphy, MTA President 1977-1978, has pioneered in the collection and technical analysis of options data since the very inception of listed options trading. She has been instrumental in persuading the Options Clearing Corporation and the various exchanges to provide data which the stock market technician can utilize. She has developed a number of techniques for the analysis of options data and has been instrumental in assisting others in the development of such techniques. Despite the expansive growth in options trading, technical analysis of options data remains in its infancy. In this article, Bernadette gives an overview of the options trading mechanisms, the data currently available, and outlines some analytical techniques which have proved helpful.
THE STRUCTURE
The Chicago Board of Options began operations on April 26, 1973. It offered options on the underlying stocks of sixteen companies. It had taken four years of planning and development, but the result was a revolutionary change in option trading. Contracts with uniform strike prices and expiration dates were offered to the public for the first time. By structuring and limiting the selection of prices and expirations, offerings were concentrated, producing greater liquidity than ever before available in option trading.
To provide clearing facilities for the trading of contracts, The Options Clearing Corp. was organized as a Delaware corporation in 1972 under the name of Chicago Board Options Exchange Clearing Corp., a wholly owned subsidiary of the CBOE. On January 3, 1975, the American Stock Exchange purchased one half of the outstanding stock of the clearing corporation just prior to the inauguration of its own options exchange on January 13. The Philadelphia -Baltimore – Washington Exchange followed in June, 1975, the Pacific Stock Exchange in April, 1976, and finally, the Midwest Option Exchange in December, 1976. The Midwest Option Exchange merged with CBOE earlier this year. The Options Clearing Corp. is now owned equally by the four exchanges.
The Options Clearing Corporation clears all transactions in the 283 calls and 172 puts currently traded in addition to trades in 15 dually-listed calls and 6 puts. It serves as the issuer and obliger of all listed and traded option contracts on participating exchanges. It supervises margin deposits of clearing members, i.e., cash, U . S . Treasury Bills, Letters of Credit, and shares of underlying stock. It also collects pertinent statistical data, much of which is made available to the officers and directors of each exchange. At the request of The Market Technicians Association, weekly and monthly data sheets became available to market analysts beginning the summer of 1979. Overall exchange open-interest figures are reported daily in the newspaper with the open interest in individual issues reported weekly in The Sunday New York Times and Barron’s. The uncovered short position as a
percentage of open interest during 1979 was estimated to average 24% by CBOE. Figures on short positions are not made public.
The Securities and Exchange Commission permitted the addition of puts to exchange option trading in June, 1977. Put options on the underlying common stock of 25 corporations were offered, in contrast to calls which, at that time, were offered on the underlying stock of 220 companies. Each exchange was allocated five puts. In October, 1977, the SEC began an evaluation study of the options market. During this period, a moratorium was imposed whereby each exchange agreed not to list options on any new underlying securities which were not listed and traded on that exchange on July 15, 1977, excepting the replacement of involuntarily delisted classes by new classes. The moratorium came to an end in May of this year.
There has been an increase in listings since that time. As an example, the Chicago Board of Options now offers puts on the underlying common of 50 companies versus the original 5 and calls of 120 companies versus the premoratorium 95. The Amex lists 78 calls and 54 puts.
REPORTED FIGURES – Public Customer
The reporting figures collected by The Options Clearing Corp. are broken down into three classifications. They are the public customer, firm proprietary, and the market maker. The term public customer includes the general public which is a combination of retail and institutional clients, but it also includes professional traders who clear their transactions through firms who are members of The Options Clearing Corporation. All orders entered by member firms doing customer orders not marked “firm proprietary” fall
into this classification. Also, a member firm does not mark on the order ticket forwarded to the clearing corporation whether the customer is retail or institutional. Without these distinctions, The Options Clearing Corp. cannot accurately refine the reporting figures within this important class.
The public customer represents a major component of overall options trading. For continuity, only figures on the Chicago Board of Options and the AMEX will be included in this article.
PUBLIC CUSTOMER
During the hectic bull market of 1975-1976, there was record participation by the public customer. Peak months were established on the Amex:
A somewhat lower record period was set in the first quarter of 1976:
Public customer percentages tend to be more striking on the Amex due to a difference in trading structure from the CBOE. On the CBOE , a competing market system is in effect, whereas the traditional specialist system prevails on the Amex. The Amex believes its volume figures tend to be weighted on the side of the public customer.
A gradual shift in the balance of the public-customer figures away from the retail and trader influence of the 1975-1976 period seems to be taking place as institutions are accepting options as a portfolio tool.
Peter Thayer conducted a survey of bank trust and estate departments in conjunction with his master’s thesis at Harvard University. Mr. Thayer has periodically updated the original survey, Options Achieve Respectability With Trust Departments, 115 Trusts and Estates 592. In 1973, 50% of those that responded to the survey viewed writing options as not prudent and 14% thought it too risky.
By April, 1976, the writing of options was considered neither imprudent nor risky by any of the respondents in a survey of 200 of the largest banks in the country. 81% of the banks answering the survey said they expected to be writing options within the next three years.
In the spring of 1977, all U .S. Trust departments over $100 million in size, or approximately 350, were questioned. The survey indicated 76.2% of the respondents felt the Comptroller of the Currency should allow option utilization beyond what was already approved.
- 29% felt trust departments of national banks should be allowed to purchase calls.
- 37% felt they should be allowed to purchase puts.
- 45% felt they should be able to write puts.
In December, 1979, the Comptroller of the Currency granted national banks the authority to establish option programs if appropriate. Mr. Thayer will soon be undertaking another update of his original survey.
The Institutional Investor conducted a review of the attitude of pension funds towards options. In August, 1976, .9% of those questioned had established option programs. By February, 1979, 9% were involved in option programs with an additional 8% considering establishing programs within the year. The number of insurance companies engaged in option writing and/or trading is unknown.
In December, 1974, Robert Nathan Associates, in Review of Initial Trading Experience of The Chicago Board Options Exchange, estimated institutional participation to be about 5% of the total customer business. By 1976, the figure was estimated to be 10%. The CBOE currently uses a rough estimate of 12-15% which may prove to be conservative.
The growth of the institutional participation should increase the sophistication of the trading techniques within this category. The
performance of this group in the market will be traced later in this article.
Firm Proprietary
Firm proprietary transactions are those for a member firm’s own account. Options may have impacted stock-exchange member trading more than any other reporting class. The growth of institutional investor activity as a percentage of stock exchange trading volume during the 1960’s and early 1970’s sorely strained the capacity of member firms and specialists to meet the liquidity needs of these large investors. Options provide a much-needed and highly effective tool. It gives member firms an alternative to the accommodative buy high-risk, costly process of positioning blocks of stocks.
With access to options, buy side orders can be shorted and hedged by calls. Long positions can generate income through covered writing, thus reducing carrying costs. Puts can provide the block trader with time to find an interested buyer or await improved market conditions before liquidating a position. There are multiple possibilities available to firm trading departments because of options. The contribution made by options is reflected in the growth of block trading, i.e., trades of 10,000 shares or
more, over the past ten years particularly since 1977.
Firm trading as a percentage of overall trading does not compare with the volume of the two other major reporting categories, public customer and market maker.
The importance of the option activity by firm trading, aside from block trading, may well be in its influence on the figures member firms report to the New York Stock Exchange on their own trading. There has been a gradual increase in member-firm short sales on the NYSE as a percentage of all sales. An obvious increase in short selling participation over the last four years (1976-1979) compared to the earlier four-year period (1972-1975) can be seen from the following table. Public short figures are the third reporting category, but are not included in the table:
Options may have also become an internal tool by which member firms are able to improve firm liquidity during periods of high interest rates. Improved liquidity lessens a firm’s dependence upon banks for expensive broker loans. Many strategies can be employed. Simply stated, a stock is sold short. A call is purchased to hedge the position. The net after option proceeds become available for internal use, such as helping to finance a customer’s margin account. As the short sale is hedged by a call, the firm’s capital reporting figure for NYSE purposes is not impacted; a customer’s margin account is financed internally; a loan at the bank is eliminated or greatly reduced in size.
Market Maker
The volume complement to the public customer is the market maker on the CBOE, and the specialist on the Amex who trades exclusively for his /her own account, making bids and offers to provide liquidity for the market. It provides a contra-trend performance in the options market to the public customer.
On the Amex there are 182 specialists registered in options of which approximately 90-100 are actively making markets in options. On the CBOE, the total membership prior to the merger with the Midwest Exchange, was 1,250, of which at least 500 were regular market makers. This is a fluid number due to the flexibility in market making provided by The Exchange. At times, as many as 700 may be acting as market makers. After the merger with the Midwest Options Exchange, the CBOE added an additional 390 special members whose trading participation is limited to the 16 issues originally traded on The Midwest. Of the special members, 155 are registered as market makers and floor brokers. In practice, approximately two thirds of the total number are market makers.
TRADING TRENDS
Market analysts have been working with limited resources when faced with analyzing the options market and its interrelationship with the senior stock market. The Options Clearing Corp. began to issue statistics during the summer of 1979. Back data has been promised on all of the published series but remains unavailable at this time. By gradually collecting and comparing figures, certain early trends are beginning to appear. These observations are presented with some serious reservations. There is a limited amount of data available and the time frame covered is short. Conclusions reached must be classified as tentative at best.
Volume
The first is that option activity in the public customer category tends to contract as a percentage of overall volume as the senior equity market declines and conversely, increases as the senior market advances.
Put /Call Ratio
A second statistic, put activity relative to call activity, increases to exceptionally high levels in all reporting categories at low points in the equity market. This spring when the moratorium was lifted, an additional 142 puts became available for trading versus the 25 traded during the prior three years. This marked increase diminished the importance of past ratio figures as a reference. Time will be required for a balance to return to this measurement as the ratio has reached a higher working plateau. Additional market swings will be needed to establish a new reference point.
A simple ratio is constructed by combining the total volume of puts divided by the total volume of calls. Weekly figures become available from The OCC in June, 1979. Since June, 1980, daily figures are reported in the newspaper.
A monthly survey of put /call activity from June, 1979June, 1980 indicated a confirmation of stock market turning points was possible through use of the ratio. In the past, the actual ratio figure had been expanding at turning points due to the limited number of available puts at a time when there was a growing demand due to increasing sophistication in option usage. Extreme levels were still easily identified.
Flow of Funds/Public Customer
A plethora of strategies have evolved in the options market. There are bull, bear, and neutral market strategies. To compensate for this situation, a simple netting of positions was adopted to simplify the tracing of market activity by various reporting categories. The objective is to determine whether the balance of the activity has a bullish or a bearish bias. The figures used in the following illustration are monthly volume figures of the public customer’s activity on the Amex which were collected before The OCC began to issue its statistics. Average premiums were not accumulated during this period. It is the net percentage of the public customer as a percentage of total volume. In studying the monthly activity figures of the public customer, an interesting pattern started to become apparent at stock market turning points. The public customer, on balance, tends to sell puts at low points and buy calls.
It wasn’t until weekly figures became available with average premiums that the trend could be confirmed. By netting the buy/sells of the public customer, times the appropriate average call or put premium, and then accumulating the figure as one does in market breadth calculations, an interesting pattern emerges. At high points in the market, the amount of money flowing into calls drops sharply. It expands dramatically at low points in the market. A contra-trend occurs in puts. One must be cautioned. These figures measure only a brief period in option market history.
A sharp drop in the flow of funds into calls over a few weeks’ time might well be construed as warning to carefully reexamine one’s indicators of the senior stock market. A reversal of trend may be in the offing.
Premiums
Premiums are certainly an expression of investor expectations for the underlying stocks but the exchanges believe they are also influenced by actual and anticipated interest rate trends. A stock-exchange firm may be increasingly aggressive in the utilization of the options market to offset block trades and to generate cash for internal use during periods of rising money rates, creating upward pressure on premiums. Customers may increasingly take advantage of the leverage offered by options. Buying options rather than the underlying stocks requires a cash commitment but helps to keep debit balances at a minimum during a period of high interest rates. The risk is partially counterbalanced by the leverage provided by lower carrying cost. When studying premiums, absolute numbers may be misleading but trends are interesting.
Both the CBOE and the Amex have developed call and put indices which concentrate on premiums but with consideration given to the expiration characteristic of options. The CBOE index was developed by Tom Rzepski and reflects premiums from that exchange. In creating the index, adjusted for the dissipating value of the option due to a set expiration date, CBOE learned premiums can decline while stocks are rising in price during a period when traders expect interest rates to drop. This occurred in 1976. In 1977 premiums reached a low seven months before the S & P (see chart, CBOE S & P 500). A detailed explanation of the methodology of constructing the index can be obtained from their Research Department. Write and ask for the “CBOE Call Option Index Methodology and Technical Consideration.” Barron’s prints the index weekly.
The Amex has created an industry-wide index which measures premium level of both calls and puts. The Amex index is computed daily. Descriptive material was distributed at the Market Technician’s option meeting at The NYSSA in June. Tapes of the meeting are available from The New York Society of Security Analysts. (Editor’s note: This refers to the meeting in June 1980 and the tapes that are referenced here are no longer available.)
Average Dollar Premiums
During an advancing period in the market, the demand for calls results in a higher premium being asked by the seller to write a contract. The premium provides compensation for the risk that the option will be exercised. In addition, the writer is capitalizing upon the profit opportunity created by market forces. As the market advances, the buyer is less inclined to pay a high premium for a put but will pay a higher premium for a call. A reverse attitude prevails during market declines. The professional option trader,
individual or institution, will supply or write calls capturing higher premium income during an advancing period in the market in calls considered to be overvalued and at the same time accumulate puts which are less in demand thus offered at low premiums and considered to be undervalued. Opposite procedures take place during a declining period in the market when the professional accumulates calls and offers puts.
As market forces do exert influence on premiums, there does seem to be a relevance to watching the trend of premium levels. A ratio of the dollar premiums puts/calls over the past year is outlined below:
New Indicators
Members of The Market Technicians Association are successfully applying the data made available to them by The Options Clearing Corp.
Gail Dudak and Dick Orr of Pershing & Co. have taken the figures provided by The OCC and constructed ratios of customer and firm buy/sell activity. It produces a measurement of option activity for the two reporting classes, but they have taken the process one step further. By producing a ratio of the ratios they have achieved interesting results. When the customer ratio/firm ratio drops below .75, a constructive attitude toward the stock market appears warranted. Note the high points.
Firm Proprietary
Although firm figures are a relatively small percentage of overall trading, this category represents a very sophisticated market sector. Arthur Merrill of Merrill Analysis, publishes a measurement of firm trading in his Technical Trends. It is an interesting refinement of the figures. Its objective is to -the bullish or bearish attitudes of the sophisticated trader. The formula is on the chart. It reads:
100 * (Call Buy + Put Sells – Calls Sells – Put Buys)
An exponential average of the figures is charted.
Other Data
Barron’s began to publish traditional breadth figures for the CBOE on June 21, 1980. The figures to date are:
Back data should be available on this series as the figures are collected daily. They were offered to the MTA in 1978 at which time they contained daily trading statistics from October, 1976 to August, 1978.
The Technician and the Options Market
The following growth pattern for one options exchange confirms a need for extra effort on the part of analysts to understand the options market. Each contract represents an option on 100 shares of stock.
The option market offers leverage and provides liquidity to the stock market. As it expands in its number of offerings and as investors’ education and appreciation of its function deepens, its growing importance will influence the entire financial industry. It is important that we as market analysts acknowledge this new force and combine our talents to study the long range implications for our specialty. By sharing our knowledge, our effectiveness as professionals will be strengthened.
