INTRODUCCIÓN

El ejercicio de una opción call antes del vencimiento no proporciona, normalmente, un beneficio económico, ya que:

• Tiene como resultado la pérdida de cualquier valor temporal de la opción que quede;
• Requiere una mayor inversión de capital para el pago o financiación de la entrega de acciones; y
• Puede exponer al titular de la opción a un mayor riesgo de pérdida sobre la acción en relación con la prima de la opción.

Aún así, para titulares de cuenta que tengan la capacidad de cumplir los requisitos de préstamo o de aumento de capital y de hacer frente a un riesgo potencialmente mayor de caída del mercado, puede ser económicamente beneficioso solicitar un ejercicio temprano de una opción call de tipo americano para capturar un próximo dividendo.

TRASFONDO

Como trasfondo, el titular de una opción call no tiene derecho a recibir un dividendo de la acción subyacente ya que este dividendo solo se devenga para los titulares de acciones en la fecha de cierre de registro de su dividendo. En igualdad de condiciones, el precio de la acción debería decaer en una cantidad igual al dividendo en la fecha ExDividendo. Aunque la teoría del precio de opciones sugiere que el precio call reflejará el valor descontado de los dividendos esperados pagados durante su duración, es posible que decline en la fecha exdividendo.  Las condiciones que convierten este escenario en más probable y que hacen más favorable la decisión de un ejercicio temprano son las siguientes:

1. La opción está muy en dinero y tiene una delta de 100;

2. La opción no tiene valor temporal o tiene muy poco;

3. El dividendo es relativamente elevado y su fecha ex precede a la fecha de vencimiento de la opción.

EJEMPLOS

Para ilustrar el impacto de estas condiciones sobre una decisión de ejercicio temprano, consideremos una cuenta que mantenga un saldo en efectivo largo de 9,000 USD y una posición de call larga en un valor hipotético “ABC”, con un precio de ejecución de 90.00 USD y un tiempo hasta vencimiento de 10 días. ABC, que actualmente opera a 100.00 USD, ha declarado un dividendo de 2.00 USD por acción, siendo mañana la fecha exdividendo. También asumiremos que el precio de opción y el precio de acción se comportan de forma similar y declinan según la cantidad de dividendo en la fecha ex.

Aquí, revisaremos la decisión de ejercicio con la intención de mantener la posición de delta de 100 y maximizar la liquidez total mediante dos asunciones de precio de opción; una en la que la opción se vende a la par y otra sobre la par.

ESCENARIO 1: precio de opción a la par - 10.00 USD
En el caso de una opción que opere a la par, el ejercicio temprano servirá para mantener la delta de la posición y evitar la pérdida de valor en la opción larga cuando la acción opere exdividendo. Aquí, el producto en efectivo se aplica en su totalidad a la compra de la acción al precio de ejercicio, la prima de la opción se pierde y la acción, neta de dividendo, y el dividendo pendiente de pago se acreditan en la cuenta.  Si busca el mismo resultado al vender la opción antes de la fecha ex dividendo y comprar la acción, recuerde que debe factorizar las comisiones/diferenciales:

ESCENARIO 2: precio de opción sobre la par - 11.00 USD
En el caso de una opción que opere sobre la par, el ejercicio temprano para capturar el dividendo podría no ser económicamente beneficioso. En este escenario, el ejercicio temprano tendría como resultado una pérdida de 100 USD en valor temporal de la acción, mientras que la venta de la opción y la compra de la acción, después de pagar comisiones, podría ser menos beneficiosa que no realizar ninguna acción. En este escenario, la acción preferible habría sido No actuar.

NOTA: los titulares de cuenta que mantengan una posición call larga como parte de un diferencial deberían prestar particular atención al riesgo de no ejercitar el tramo largo dada la posibilidad de que se asigne en el tramo corto. Hay que tener en cuenta que la asignación de una opción call corta tiene como resultado una posición corta en acciones y los titulares de posiciones cortas en acciones en la fecha de registro del dividendo están obligados a pagar el dividendo al prestador de las acciones. Además, el ciclo de procesamiento de la cámara de contratación para notificaciones de ejercicio no acepta entregas de notificaciones de ejercicio como respuesta a la asignación.

Como ejemplo, consideremos un diferencial de opción call de crédito (bajista) para SPDR S&P 500 ETF Trust (SPY) que consista en 100 contratos cortos al precio de ejercicio de 146 USD en marzo de 2013 y 100 contratos largos al precio de ejercicio de 147 USD en marzo de 2013.  El 14 de marzo de 2013, el SPY Trust declaró un dividendo de 0.69372 USD por acción, pagadero el 30 de abril de 2013 a los accionistas registrados a fecha del 19 de marzo de 2013. Dado el periodo de tres días hábiles para la liquidación para acciones estadounidenses, habría que haber comprado la acción el 14 de marzo de 2013 a más tardar, para recibir el dividendo, ya que al día siguiente la acción empezó a operar exdividendo.

El 14 de marzo de 2013, con un día de negociación previo al vencimiento, los dos contratos de opciones operaron a la par,  lo que sugiere el riesgo máximo de 100 USD por contrato o 10,000 USD en la posición de100 contratos. Sin embargo, el no ejercitar el contrato largo para capturar el dividendo y protegerse frente a la probable asignación de los contratos cortos por parte de aquellos que buscaran el dividendo creó un riesgo adicional de 67.372 USD por contrato o 6,737.20 USD en la posición que represente la obligación de dividendo una vez asignadas todas las call cortas.  Como se ve en la tabla siguiente, si el tramo de la opción corta no se hubiera asignado, el riesgo máximo cuando se determinaron los precios de liquidación del contrato final el 15 de marzo de 2013 habría permanecido en 100 USD por contrato.

Por favor, tenga en cuenta que si su cuenta está sujeta a requisitos de retenciones fiscales bajo la norma 871(m) del Tesoro estadounidense, podría ser beneficioso cerrar una posición larga en opciones antes de la fecha exdividendo y reabrir la posición después de la fecha exdividendo.

INTRODUCTION

Exercising an equity call option prior to expiration ordinarily provides no economic benefit as:

• It results in a forfeiture of any remaining option time value;
• Requires a greater commitment of capital for the payment or financing of the stock delivery; and
• May expose the option holder to greater risk of loss on the stock relative to the option premium.

Nonetheless, for account holders who have the capacity to meet an increased capital or borrowing requirement and potentially greater downside market risk, it can be economically beneficial to request early exercise of an American Style call option in order to capture an upcoming dividend.

BACKGROUND

As background, the owner of a call option is not entitled to receive a dividend on the underlying stock as this dividend only accrues to the holders of stock as of its dividend Record Date. All other things being equal, the price of the stock should decline by an amount equal to the dividend on the Ex-Dividend date. While option pricing theory suggests that the call price will reflect the discounted value of expected dividends paid throughout its duration, it may decline as well on the Ex-Dividend date.  The conditions which make this scenario most likely and the early exercise decision favorable are as follows:

1. The option is deep-in-the-money and has a delta of 100;

2. The option has little or no time value;

3. The dividend is relatively high and its Ex-Date precedes the option expiration date. 

EXAMPLES

To illustrate the impact of these conditions upon the early exercise decision, consider an account maintaining a long cash balance of $9,000 and a long call position in hypothetical stock “ABC” having a strike price of $90.00 and time to expiration of 10 days. ABC, currently trading at $100.00, has declared a dividend of $2.00 per share with tomorrow being the Ex-Dividend date. Also assume that the option price and stock price behave similarly and decline by the dividend amount on the Ex-Date.

Here, we will review the exercise decision with the intent of maintaining the 100 share delta position and maximizing total equity using two option price assumptions, one in which the option is selling at parity and another above parity.

SCENARIO 1: Option Price At Parity - $10.00
In the case of an option trading at parity, early exercise will serve to maintain the position delta and avoid the loss of value in long option when the stock trades ex-dividend, to preserve equity. Here the cash proceeds are applied in their entirety to buy the stock at the strike, the option premium is forfeited and the stock (net of dividend) and dividend receivable are credited to the account.  If you aim for the same end result by selling the option prior to the Ex-Dividend date and purchasing the stock, remember to factor in commissions/spreads:

SCENARIO 2: Option Price Above Parity - $11.00
In the case of an option trading above parity, early exercise to capture the dividend may not be economically beneficial. In this scenario, early exercise would result in a loss of $100 in option time value, while selling the option and buying the stock, after commissions, may be less beneficial than taking no action. In this scenario, the preferable action would be No Action.

NOTE:

Options have two components that make up their total premium value - intrinsic value and time value. The intrinsic value is the amount by which the option is in-the-money, while the time value represents the possibility that the option could become even more profitable before expiration as the underlying asset price fluctuates while providing protection against adverse moves.

Many options are American-style, which means they can be exercised early, ahead of their expiration date. Early exercise of an option eliminates the remaining time value component from the option's premium, since the option holder loses protection against unfavorable movements in the underlying asset’s price.

This makes early exercise suboptimal in most situations, as the option holder is willingly forfeiting a portion of the option's value.

There are a few specific circumstances where early exercise could make sense, such as:

• For call options on a stock that will pay dividends soon, where the dividend amount exceeds the remaining time value (and only if the exercise will settle on or prior to the record date for the dividend).
• For deep in-the-money options where the time value is negligible compared to the intrinsic value, and the option is expected to drop in value due to interest rate effects (PUTS), or expected stock loan benefits (CALLS).

The first case, exercising an in the money call immediately ahead of a dividend payment, is the most common economically-sensible early exercise. In most cases, it is advisable to hold or sell the option instead of exercising it early, in order to capture the remaining time value. An option should only be exercised early after carefully considering all factors and determining that the benefits of early exercise outweigh the time value being surrendered.

Account holders holding a long call position as part of a spread should pay particular attention to the risks of not exercising the long leg given the likelihood of being assigned on the short leg.  Note that the assignment of a short call results in a short stock position and holders of short stock positions as of a dividend Record Date are obligated to pay the dividend to the lender of the shares. In addition, the clearinghouse processing cycle for exercise notices does not accommodate submission of exercise notices in response to assignment.

As example, consider a credit call (bear) spread on the SPDR S&P 500 ETF Trust (SPY) consisting of 100 short contracts in the March '13 $146 strike and 100 long contracts in the March '13 $147 strike.  On 3/14/13, with the SPY Trust declared a dividend of $0.69372 per share, payable 4/30/13 to shareholders of record as of 3/19/13. Given the 3 business day settlement time frame for U.S. stocks, one would have had to buy the stock or exercise the call no later than 3/14/13 in order receive the dividend, as the next day the stock began trading Ex-Dividend. 

On 3/14/13, with one trading day left prior to expiration, the two option contracts traded at parity, suggesting maximum risk of $100 per contract or $10,000 on the 100 contract position. However, the failure to exercise the long contract in order to capture the dividend and protect against the likely assignment on the short contracts by others seeking the dividend created an additional risk of $67.372 per contract or $6,737.20 on the position representing the dividend obligation were all short calls assigned.  As reflected on the table below, had the short option leg not been assigned, the maximum risk when the final contract settlement prices were determined on 3/15/13 would have remained at $100 per contract.

Please note that if your account is subject to tax withholding requirements of the US Treasure rule 871(m), it may be beneficial to close a long option position before the ex-dividend date and re-open the position after ex-dividend.

Risk Warning

CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage.

61% of retail investor accounts lose money when trading CFDs with IBKR.

You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

ESMA Rules for CFDs (Retail Clients of IBKRs European entities, including so-called F segments)

The European Securities and Markets Authority (ESMA) has enacted new CFD rules effective 1st August 2018.

The rules include: 1) leverage limits on the opening of a CFD position; 2) a margin close out rule on a per account basis; and 3) negative balance protection on a per account basis.

The ESMA Decision is only applicable to retail clients. Professional clients are unaffected.

Please refer to the following articles for more detail:

ESMA CFD Rules Implementation at IBKR (UK) and IBKR LLC

ESMA CFD Rules Implementation at IBIE and IBCE

I.  Overview

IBKR CFDs are OTC contracts which deliver the return of the underlying stock, including dividends and corporate actions (read more about CFD corporate actions).

Said differently, it is an agreement between the buyer (you) and IBKR to exchange the difference in the current value of a share, and its value at a future time. If you hold a long position and the difference is positive, IBKR pays you. If it is negative, you pay IBKR.

Our Share CFDs offer Direct Market Access (DMA). Our Share CFD quotes are identical to the Smart-routed quotes for shares that you can observe in the Trader Workstation. Similar to shares, your non-marketable (i.e. limit) orders have the underlying hedge directly represented on the deep book of those exchanges at which it trades.  This also means that you can place orders to buy the CFD at the underlying bid and sell at the offer.

To compare IBKR’s transparent CFD model to others available in the market please see our Overview of CFD Market Models.

We currently offer approximately 8500 Share CFDs covering the principal markets in the US, Europe and Asia. Eligible shares have minimum market capitalization of USD 500 million and median daily trading value of at least USD 600 thousand.  Please see CFD Product Listings for more detail. 

Most order types are available for CFDs, including auction orders and IBKR Algos. 

CFDs on US share can also be traded during extended exchange hours and overnight. Other CFDs are traded during regular hours.

II.   Comparison Between CFDs and Underlying Shares

*IB LLC and IB-UK accounts.

**EEA area clients cannot trade US ETFs directly, as they do not publish KIDs.

III. CFD Tax and Margin Advantage

Where stamp duty or financial transaction tax is applied, currently in the UK (0.5%), France (0.3%), Belgium (0.35%) and Spain (0.2%), it has a substantially detrimental impact on returns, particular in an active trading strategy. The taxes are levied on buy-trades, so each time you open a long, or close a short position, you will incur tax at the rates described above.

The amount of available leverage also significantly impacts returns. For European IBKR entities, margin requirements are risk-based for both stocks and CFDs, and therefore generally the same. IB-UK and IB LLC accounts however are subject to Reg T requirements, which limit available leverage to 2:1 for positions held overnight.

To illustrate, let's assume that you have 20,000 to invest and wish to leverage your investment fully. Let's also assume that you hold your positions overnight and that you trade in and out of positions 5 times in a month.

Let's finally assume that your strategy is successful and that you have earned a 5% return on your gross (fully leveraged) investment.

The table below shows the calculation in detail for a UK security. The calculations for France, Belgium and Spain are identical, except for the tax rates applied.

The following table summarizes the reduction in return for a stock investment, by country where tax is applied, compared to a CFD investment, given the above assumptions.

IV. US ETFs

EEA area residents who are retail investors must be provided with a key information document (KID) for all investment products. US ETF issuers do not generally provide KIDs, and US ETFs are therefore not available to EEA retail investors.

CFDs on such ETFs are permitted however, as they are derivatives for which KIDs are available.

Like for all share CFDs, the reference price for CFDs on ETFs is the exchange-quoted, SMART-routed price of the underlying ETF, ensuring economics that are identical to trading the underlying ETF.

V.   Extended and Overnight Hours

US CFDs can be traded from 04:00 to 20:00EST, and the again overnight from 20:00 to 03:30 the following day. Trades in the overnight session are attributed to the day when the session ends, even if a trade is entered before midnight the previous day. This has implications for corporate actions and financing.

Trades entered before midnight on the day  before ex-date will not have a dividend entitlement. Trades before midnight will settle as if they had been traded the following day, delaying the start of financing.

VII.  Frequently Asked Questions

What Stocks are available as CFDs?

Large and Mid-Cap stocks in the US, Western Europe, Nordic and Japan. Liquid Small Cap stocks are also available in many markets. Please see CFD Product Listings for more detail. More countries will be added in the near future.

Do you have CFDs on other asset classes?

Yes. Please see IBKR Index CFDs - Facts and Q&A, Forex CFDs - Facts and Q&A and Metals CFDs - Facts and Q&A.

How do you determine your Share CFD quotes?

IBKR CFD quotes are identical to the Smart routed quotes for the underlying share. IBKR does not widen the spread or hold positions against you. To learn more please go to Overview of CFD Market Models.

Can I see my limit orders reflected on the exchange?

Yes. IBKR offers Direct market Access (DMA) whereby your non-marketable (i.e. limit) orders have the underlying hedges directly represented on the deep books of the exchanges on which they trade. This also means that you can place orders to buy the CFD at the underlying bid and sell at the offer. In addition, you may also receive price improvement if another client's order crosses yours at a better price than is available on public markets.

How do you determine margins for Share CFDs?

IBKR establishes risk-based margin requirements based on the historical volatility of each underlying share. The minimum margin is 10%, making CFDs more margin-efficient than trading the underlying share in many cases.  Retail investors are subject to additional margin requirements mandated by the European regulators. There are no portfolio off-sets between individual CFD positions or between CFDs and exposures to the underlying share. Concentrated positions and very large positions may be subject to additional margin. Please refer to CFD Margin Requirements for more detail.

Are short Share CFDs subject to forced buy-in?

Yes. In the event the underlying stock becomes difficult or impossible to borrow, the holder of the short CFD position may become subject to buy-in.

How do you handle dividends and corporate actions?

IBKR will generally reflect the economic effect of the corporate action for CFD holders as if they had been holding the underlying security. Dividends are reflected as cash adjustments, while other actions may be reflected through either cash or position adjustments, or both. For example, where the corporate action results in a change of the number of shares (e.g. stock-split, reverse stock split), the number of CFDs will be adjusted accordingly. Where the action results in a new entity with listed shares, and IBKR decides to offer these as CFDs, then new long or short positions will be created in the appropriate amount. For an overview please CFD Corporate Actions.

*Please note that in some cases it may not be possible to accurately adjust the CFD for a complex corporate action such as some mergers. In these cases IBKR may terminate the CFD prior to the ex-date.

Can anyone trade IBKR CFDs?

All clients can trade IBKR CFDs, except residents of the USA, Canada, Hong Kong, New Zealand and Israel. There are no exemptions based on investor type to the residency based exclusions.

What do I need to do to start trading CFDs with IBKR?

You need to set up trading permission for CFDs in Client Portal, and agree to the relevant disclosures. If your account is with IBKR (UK) or with IBKR LLC, IBKR will then set up a new account segment (identified with your existing account number plus the suffix “F”). Once the set-up is confirmed you can begin to trade. You do not need to fund the F-account separately, funds will be automatically transferred to meet CFD initial margin requirements from your main account.  

If your account is with another IBKR entity, only the permission is required; an additional account segment is not necessary.

Are there any market data requirements?

The market data for IBKR Share CFDs is the market data for the underlying shares. It is therefore necessary to have market data permissions for the relevant exchanges. If you already have market data permissions for an exchange for trading the shares, you do not need to do anything. If you want to trade CFDs on an exchange for which you do not currently have market data permissions, you can set up the permissions in the same way as you would if you planned to trade the underlying shares.

How are my CFD trades and positions reflected in my statements?

If you are a client of IBKR (U.K.) or IBKR LLC, your CFD positions are held in a separate account segment identified by your primary account number with the suffix “F”. You can choose to view Activity Statements for the F-segment either separately or consolidated with your main account. You can make the choice in the statement window in Client Portal.

If you are a client of other IBKR entities, there is no separate segment. You can view your positions normally alongside your non-CFD positions.

Can I transfer in CFD positions from another broker?

IBKR does not facilitate the transfer of CFD positions at this time.

Are charts available for Share CFDs?

Yes.

In what type of IBKR accounts can I trade CFDs e.g., Individual, Friends and Family, Institutional, etc.? 

All margin and cash accounts are eligible for CFD trading. 

What are the maximum a positions I can have in a specific CFD?

There is no pre-set limit. Bear in mind however that very large positions may be subject to increased margin requirements. Please refer to CFD Margin Requirements for more detail.

Can I trade CFDs over the phone?

No. In exceptional cases we may agree to process closing orders over the phone, but never opening orders.

Foreign stocks listed for trading in Japan which issue dividends will have the cash dividend allocation subject to an increased withholding tax rate. The tax will vary based on the domicile of the stock issuing the dividend; however in general the withholding rate will be the highest withholding rate applicable and will not incorporate a reduction based on prevailing tax treaties.

This treatment is due to the tax reporting status of Interactive Brokers's clearing agent. As our clearing agent is unable to process the relevant tax declaration documentation which would allow for the application of tax withholding at a reduced rate, shareholders will be subject to the highest rate.

In order to avoid the application of the tax withholding on the dividends of foreign stocks, positions in such dividend paying stocks should be closed prior to the ex-dividend date.

We recommend that customers consult with their tax advisor for assistance in determining the eligibility, if any, for a tax credit on this withholding.

A list of foreign stocks and their applicable rates is provided below. Please be aware that the below is for informational purposes only and may not include all stocks which may be subject to the higher withholding rates.
