  • Seeking Income: Cash Flow Distribution Analysis of S&P 500
    RESEARCH Income CONTRIBUTORS Berlinda Liu Seeking Income: Cash Flow Director Global Research & Design Distribution Analysis of S&P [email protected] ® Ryan Poirier, FRM 500 Buy-Write Strategies Senior Analyst Global Research & Design EXECUTIVE SUMMARY [email protected] In recent years, income-seeking market participants have shown increased interest in buy-write strategies that exchange upside potential for upfront option premium. Our empirical study investigated popular buy-write benchmarks, as well as other alternative strategies with varied strike selection, option maturity, and underlying equity instruments, and made the following observations in terms of distribution capabilities. Although the CBOE S&P 500 BuyWrite Index (BXM), the leading buy-write benchmark, writes at-the-money (ATM) monthly options, a market participant may be better off selling out-of-the-money (OTM) options and allowing the equity portfolio to grow. Equity growth serves as another source of distribution if the option premium does not meet the distribution target, and it prevents the equity portfolio from being liquidated too quickly due to cash settlement of the expiring options. Given a predetermined distribution goal, a market participant may consider an option based on its premium rather than its moneyness. This alternative approach tends to generate a more steady income stream, thus reducing trading cost. However, just as with the traditional approach that chooses options by moneyness, a high target premium may suffocate equity growth and result in either less income or quick equity depletion. Compared with monthly standard options, selling quarterly options may reduce the loss from the cash settlement of expiring calls, while selling weekly options could incur more loss.

  • Income Solutions: the Case for Covered Calls an Advantageous Strategy for a Low-Yield World
    Income Solutions: The Case for Covered Calls An advantageous strategy for a low-yield world Covered call writing is a time-tested approach that can add income, dampen volatility and diversify both equity and fixed income core strategies. Adding a covered call strategy in a core-satellite, multi-asset-class approach can be accomplished as: • A hedged equity strategy with an “income kicker” to enhance overall income production • A supplement to a core large-cap strategy (especially late in the market cycle when valuations are long-in-the-tooth and price action is volatile) as a means of boosting income and mitigating downside risk • A better-yielding alternative to a high yield bond allocation We believe that investors are well-served by strongly considering the addition of an income-producing covered call strategy in virtually all market environments and multi-asset class strategies. Madison’s active call writing/active stock selection approach provides more opportunity for premium income and alpha from underlying security selection than common passive call writing.

INTRODUCTION TO DERIVATIVES 1. What are Derivatives? Ans. A Derivative is a financial instrument whose value is derived from the value of an underlying asset. The underlying asset can be equity shares or index, precious metals, commodities, currencies, interest rates etc. A derivative instrument does not have any independent value. Its value is always dependent on the underlying assets. Derivatives can be used either to minimize risk (hedging) or assume risk with the expectation of some positive pay-off or reward (speculation). 2. What are some common types of Derivatives? Ans. The following are some common types of derivatives: a) Forwards b) Futures c) Options d) Swaps 3. What is Forward? A forward is a contractual agreement between two parties to buy/sell an underlying asset at a future date for a particular price that is pre‐decided on the date of contract.

  • Arbitrage Spread.Pdf
    Arbitrage spreads Arbitrage spreads refer to standard option strategies like vanilla spreads to lock up some arbitrage in case of mispricing of options. Although arbitrage used to exist in the early days of exchange option markets, these cheap opportunities have almost completely disappeared, as markets have become more and more efficient. Nowadays, millions of eyes as well as computer software are hunting market quote screens to find cheap bargain, reducing the life of a mispriced quote to a few seconds. In addition, standard option strategies are now well known by the various market participants. Let us review the various standard arbitrage spread strategies Like any trades, spread strategies can be decomposed into bullish and bearish ones. Bullish position makes money when the market rallies while bearish does when the market sells off. The spread option strategies can decomposed in the following two categories: Spreads: Spread trades are strategies that involve a position on two or more options of the same type: either a call or a put but never a combination of the two. Typical spreads are bull, bear, calendar, vertical, horizontal, diagonal, butterfly, condors. Combination: in contrast to spreads combination trade implies to take a position on both call and puts. Typical combinations are straddle, strangle1, and risk reversal. Spreads (bull, bear, calendar, vertical, horizontal, diagonal, butterfly, condors) Spread trades are a way of taking views on the difference between two or more assets. Because the trading strategy plays on the relative difference between different derivatives, the risk and the upside are limited. There are many types of spreads among which bull, bear, and calendar, vertical, horizontal, diagonal, butterfly spreads are the most famous.

  • Options Trading Strategy Based on ARIMA Forecasting
    The current issue and full text archive of this journal is available on Emerald Insight at: https://www.emerald.com/insight/2399-1747.htm Options Options trading strategy based on trading ARIMA forecasting strategy Pierre Rostan Department of Business, American University of Afghanistan, Kabul, Afghanistan 111 Alexandra Rostan American University of Afghanistan, Kabul, Afghanistan, and Received 13 July 2019 Revised 1 January 2020 Mohammad Nurunnabi Accepted 23 April 2020 Department of Accounting, Prince Sultan University, Riyadh, Saudi Arabia Abstract Purpose – The purpose of this paper is to illustrate a profitable and original index options trading strategy. Design/methodology/approach – The methodology is based on auto regressive integrated moving average (ARIMA) forecasting of the S&P 500 index and the strategy is tested on a large database of S&P 500 Composite index options and benchmarked to the generalized auto regressive conditional heteroscedastic (GARCH) model. The forecasts validate a set of criteria as follows: the first criterion checks if the forecasted index is greater or lower than the option strike price and the second criterion if the option premium is underpriced or overpriced. A buy or sell and hold strategy is finally implemented. Findings – The paper demonstrates the valuable contribution of this option trading strategy when trading call and put index options. It especially demonstrates that the ARIMA forecasting method is a valid method for forecasting the S&P 500 Composite index and is superior to the GARCH model in the context of an application to index options trading. Originality/value – The strategy was applied in the aftermath of the 2008 credit crisis over 60 months when the volatility index (VIX) was experiencing a downtrend.
