Ex-post Structured Product Returns: Index Methodology and Analysis

By: Geng Deng, Tim Dulaney, Tim Husson, Craig McCann, and Mike Yan (Apr 2014)

Published in The Journal of Investing, Summer 2015, Vol. 24, No. 2: pp. 45-58.

The academic and practitioner literature now includes numerous studies of the substantial issue date mispricing of structured products but there is no large scale study of the ex-post returns earned by structured product investors. This paper augments the current literature by analyzing the ex-post returns of nearly 18,000 individual structured products issued by 13 brokerage firms since 2007. We construct our structured product index and sub-indices for reverse convertibles, single-observation reverse convertibles, tracking securities, and auto-callable securities by valuing each structured product in our database each day.

The ex-post returns of US structured products are highly correlated with the returns of large capitalization equity markets in the aggregate and individual structured products generally underperform simple alternative allocations to stocks and bonds. The observed underperformance of structured products is consistent with the significant issue date under-pricing documented in the literature.

Valuation of Structured Products

By: Geng Deng, Tim Husson, and Craig McCann (Feb 2014)

Published in The Journal of Alternative Investments, Spring 2014, Vol. 16, No. 4: pp. 71-87.

The market for structured products has grown dramatically in the past decade. Their diversity and complexity has led to the development of many different valuation approaches, and which approach to use to value a given product is not always clear. In this paper we demonstrate and discuss four approaches to valuing structured products: simulation of the linked financial instrument's future values, numerical integration, decomposition, and partial differential equation approaches. As an example, we use all four approaches to value a common type of structured product and discuss the virtues and pitfalls of each. These approaches have been practically applied to value 20,000 structured products in our database.

Valuation of Reverse Convertibles in the VG Economy

By: Geng Deng, Tim Dulaney, and Craig McCann (Jan 2014)

Published in the Journal of Derivatives & Hedge Funds 19, 244-258 (November 2013).

Prior research on structured products has demonstrated that equity-linked notes sold to retail investors in initial public offerings are typically issued at above their fair market value. A particular type of equity-linked note reverse convertibles embed down-and-in put options and other investors relatively high coupon payments in exchange for bearing some of the downside risk of the equity underlying the note. We analytically study the magnitude of the overpricing of reverse convertibles - one of the most popular structured products on the market today - within a stochastic volatility model.

We extend the current literature to include analytical valuation formulas within a model of stochastic volatility - the Variance Gamma (VG) model. We show that these complex notes are even more overpriced than previously estimated when stochastic volatility is taken into account. As a result of their complex payouts and the lack of a secondary market to correct the mispricing, reverse convertible notes continue to be sold at prices substantially in excess of their fair market value.

Structured Product Based Variable Annuities

By: Geng Deng, Tim Dulaney, Tim Husson, and Craig McCann (Sep 2013)

Published in the Journal of Retirement, Winter 2014, Vol. 1, No. 3: pp. 97-111.

Recently, a new type of variable annuity has been marketed to investors which is based on structured product-like investments instead of the mutual fund-like investments found in traditional variable annuities. Embedding a structured product into a variable annuity introduces substantial complexity into an investment typically considered conservative. In this paper, we describe structured product based variable annuity (spVA) crediting formulas and how they differ from traditional VAs, value the embedded derivative position for a range of example parameters, and calculate the fair cap levels required to fairly compensate investors for the derivative position. We also provide extensive backtests of spVA crediting formulas using our calculated cap levels and compare the results to their underlying indexes. Our findings suggest that the complexity of spVAs can be used to hide fees and reduce the comparability of variable annuities to other investments in the market.

The Rise and Fall of Apple-linked Structured Products

By: Geng Deng, Tim Dulaney, Craig McCann, and Mike Yan (Jan 2013)

The rise in Apple's market capitalization in 2012 coincided with a dramatic increase in single-observation reverse convertibles, reverse convertibles and autocallable notes linked to Apple's stock price. These notes all transfer the downside risk of owning Apple to investors but cap the upside at somewhat more than corporate bond yields. Issuers use individual stocks like Apple as the reference obligations for reverse convertible structured products because investors underestimate the risk of suffering losses when the individual stock's price falls.

The decline in Apple's stock price from over $700 in September 2012 to $450 in January 2013 has resulted in over one hundred million dollars of losses in Apple-linked structured products. In this paper, we summarize our published reports on over 650 Apple-linked structured products and identify the impact of Apple's recent stock price decline on investors in these structured products.

Dual Directional Structured Products

By: Geng Deng, Tim Dulaney, Tim Husson, and Craig McCann (Jan 2013)

Published in the Journal of Derivatives & Hedge Funds, (5 June 2014).

We analyze and value dual directional structured products - or simply dual directionals (DDs) - which have been issued in large amounts since the beginning of 2012. DD's evolved out of another type of structured product called absolute return barrier notes (ARBNs); however, DD's lack principal protection and have different embedded options positions, which have yet to be described in the literature. We find that DDs can be broadly organized into two categories: single observation dual directionals (SODDs) and knock-out dual directionals (KODDs). We determine the appropriate option decomposition for these categories and provide analytical formulas for their valuation. We confirm our analytic results using Monte Carlo simulation and use both techniques to value a large sample of DDs registered with the Securities and Exchange Commission up to December 2012. Our results indicate that like many types of structured products, DDs tend to be priced at a significant premium to present value across issuers and underlying securities and that the present value of the decomposition is smaller than the face value net of commissions. We find that DDs with embedded leverage or a single observation feature tend to be worth less than products either without leverage or with a knock-out option.

Modeling Autocallable Structured Products

By: Geng Deng, Joshua Mallett, and Craig McCann (Mar 2011)

Published in the Journal of Derivatives & Hedge Funds 17, 326-340 (November 2011).

Since first introduced in 2003, the number of autocallable structured products in the U.S. has increased exponentially. The autocall feature immediately converts the product if the reference asset's value rises above a pre-specified call price. Because an autocallable structured product matures immediately if it is called, the autocall feature reduces the product's duration and expected maturity.

In this paper, we present a flexible Partial Differential Equation (PDE) framework to model autocallable structured products. Our framework allows for products with either discrete or continuous autocall dates. We value the autocallable structured products with discrete autocall dates using the finite difference method, and the products with continuous autocall dates using a closed-form solution. In addition, we estimate the probabilities of an autocallable structured-product being called on each call date. We demonstrate our models by valuing a popular autocallable product and quantify the cost to the investor of adding this feature to a structured product.

The Anatomy of Principal Protected Absolute Return Notes

By: Geng Deng, Ilan Guedj, Joshua Mallett, and Craig McCann (Jul 2010)

Published in the Journal of Derivatives, Vol. 19, No. 2, pp. 61-70, 2011.

Principal Protected Absolute Return Barrier Notes (ARBNs) are structured products that guarantee to return the face value of the note at maturity and pay interest if the underlying security's price does not vary excessively.

The SLCG study derives four closed-form valuation approaches which are considered as representative methodologies on valuing structured products. The approaches are: 1) decomposing an ARBN's payoff into double-barrier linear segment options, 2) decomposing an ARBN's payoff into double-barrier call and put options, 3) transforming an ARBN's path-dependent payoff rule into a path-independent payoff rule which significantly simplifies the derivation of product value, and 4) using PDE (Partial Differential Equations) to model an ARBN's payoff and calculate its value. The study shows the four methodologies to value 214 publicly-listed ARBNs issued by six different investment banks. Most of the products are linked to indices such as the S&P 500 Index and the Russell 2000 Index.

The study finds that the ARBNs' fair price is approximately 4.5% below the actual issue price. Each of the ARBN's fair price is stable across all four valuation methodologies.

What TiVo and JP Morgan teach us about Reverse Convertibles

By: Geng Deng, Craig McCann, and Edward O'Neal (Jun 2010)

Reverse convertibles are short term, unsecured notes issued by brokerage firms including JP Morgan, Barclays, Citigroup, Morgan Stanley, Wachovia, Lehman Brothers, and RBC that pay less than the notes' face value at maturity if the price of the reference stock or the level of the reference stock index declines substantially during the term of the note. The SLCG study finds that brokerage firms overcharge for reverse convertibles so significantly that the expected return on these complex investments is actually negative and that reverse convertibles continue to be sold at inflated prices only because investors do not fully understand these products.

The SLCG study reports that despite substantial overpricing in the offerings and the significant losses on the reverse convertible notes in 2008 and 2009, there have been a substantial number of new issues of these dubious investments by JP Morgan, Barclays and many others brokerage firms in 2010. The study illustrates its main themes with JP Morgan's May 14, 2010 TiVo-linked reverse convertible.

Structured Products in the Aftermath of Lehman Brothers

By: Geng Deng, Guohua Li, and Craig McCann (Nov 2009)

SLCG's prior research showed that structured products were poor investments because they were significantly overpriced when offered and were, at best, thinly traded thereafter. SLCG concluded that overpriced structured products survived in the marketplace because structured products' opaqueness obscured their true risks and costs and the high fees earned by underwriters and salespersons.

The current SLCG study presents a brief history of the structured products program at Lehman Brothers and illustrates many of its points with Lehman structured products examples including Principal Protected Notes, Enhanced Return Notes, Absolute Barrier Notes, Steepeners and Reverse Convertibles. The study reports that the spectacular failure of Lehman brothers in September 2008 left investors holding more than $8 billion face value $US-denominated structured products. Dr. Craig McCann, the study's principal author, explained that the Lehman experience is especially instructive of the opportunity for mischief presented by financial engineering; faced with increasing borrowing costs Lehman stepped up its issuance of structured products where its credit risk would not be priced into the debt.
