Complex Securities and Strategies Expert Witness
Expert Witness and Litigation Support
Modern financial markets are filled with complex securities and sophisticated trading strategies whose risks, valuation, and behavior are often poorly understood outside professional trading desks.
These instruments include structured products, volatility‑linked securities, convertible financing structures, derivative or statistical strategies. While they can offer powerful investment exposures, they also create technical legal disputes involving losses, valuation disagreements, risk drivers, alleged manipulation, and regulatory issues.
Navesink International provides expert witness services in litigation and arbitration involving complex securities, derivative structures, and advanced trading strategies. Our work combines derivatives trading experience, quantitative modeling, and capital markets expertise to analyze how these instruments function and what went wrong.
What Are Complex Securities?
The term “complex securities” is widely used in financial regulation and litigation to describe instruments whose behavior depends on embedded derivatives or dynamic trading strategies.
Examples include:
- Futures, options, leveraged ETFs, zero-day options, VIX…
- Structured products (e.g. structured notes) distributed by the global banks
- Convertible bonds and equity-linked securities
- Variable annuities
- Volatility-linked derivatives, sometimes exchange-traded
- Warrants and structured equity financing
- ‘Quantitative Investment Strategies (QIS)’, or ‘liquid alts’, the strategies typically found in hedge funds, distributed through derivatives
Unlike traditional securities, the value and risk of these instruments often depend on volatility, correlations, and dynamic trading behavior rather than simply the direction of an underlying asset. None of these are liquid or even listed, making price discovery impossible by way of a secondary market. Most aren’t clearable either, creating a dependency if not a bias on the issuer’s pricing. Each instrument is unique. Understanding them requires specialized derivatives pricing expertise and trading experience.
Complex Trading Strategies and Embedded Financial Market Risks
Many financial strategies rely on option exposures that create nonlinear risks, as well as complicated exposures that only appear through the combination of many different assets.
Common examples include:
- Option-selling strategies, naked or embedded with stock exposure
- Knock-in, knock-out barrier options, digitals, in all asset classes (FX, equity, rates…)
- VIX and VIX derivatives
- Tail risk, and catastrophic insurance
- Interest rate deformations
- Statistical arbitrage portfolios, including factor exposure
- Convertible bond arbitrage
While these strategies can generate attractive returns during normal market conditions, they may experience extreme losses during periods of market stress. Several high-profile investment losses have illustrated how these strategies behave when volatility spikes or liquidity disappears.
When Complex Securities Lead to Litigation
Disputes involving complex financial instruments frequently arise when investors, counterparties, or regulators question how a strategy or security actually behaved.
Typical issues include:
- Understanding and representation of the true risks embedded in structured securities or strategies
- Trading losses associated with volatility or derivative exposures
- Valuation disagreements and ‘mis-marking’
- Allegations of market manipulation involving derivatives markets
- Questions concerning the tax treatment or economic substance of complex financial transactions
- Allegations of IP theft – computer code, methodology, strategy…
Valuation of Complex Securities and Derivatives
The valuation of structured securities frequently requires derivatives pricing techniques.
Depending on the instrument, analysis may involve:
- Parameters estimations, including volatility, correlations, rate curve construction
- Choice of valuation models from simple Black-Scholes to Monte Carlo simulations
- Valuation of the instrument, even when the proprietary source code might not be available
- Scenario analysis, and the appropriateness of such scenarios.
Market Manipulation Allegations
Derivative markets have been the subject of numerous manipulation investigations.
Examples include allegations involving:
- Benchmark manipulations: Libor, VIX…
- Manipulation of underlying assets: binary options, treasury, commodities ‘cornering’
- Manipulation of final valuations: credit auctions
- Manipulation of a class of instruments: Allianz Structured Alpha
- Mis-grading of Asset-Backed and Credit Securities.
- Spreading of rumors
Arbitrage Strategies, Hedging Strategies and Market Structure
Sophisticated investors frequently deploy arbitrage or complex hedging strategies designed to exploit pricing inefficiencies between related instruments or eliminate unwanted risks and economic exposures.
Arbitrage strategies may involve:
- Volatility arbitrage: skew, term structure, dispersion, tail risks
- Arbitrage between classes of products – listed vs OTC, variance swaps vs listed options vs VIX, ETF vs futures
- Index- vs component- securities, ‘cash-and-carry’, implicit financing, ETF replication, dispersion
Hedging may involve:
- Using FX options and Forwards contracts via Tarfs (Target Redemption Forwards) or Timed Option products.
- Interest rate Swaptions – Caps and Collars
- Mortgage-backed Amortizing Swaps
- Proxy hedges
- Dynamic replication
Disputes can arise when these strategies fail or when market participants question whether trading activity distorted market prices.
Tax and Economic Substance Issues
Certain financial strategies involve complex tax considerations or structured financing arrangements.
Courts may examine:
- The economic substance of the transaction
- The right to offset gains and losses
- The true financial risks involved
- The economic incentives created by derivative structures
Expert analysis may be required to explain how a strategy operates economically and whether it has genuine financial purpose beyond tax considerations.
Representative Matters
Warrant and Convertible Bond Valuation
Facts: A biotechnology company issued bonds convertible into its stocks and warrants on its stock. A dispute later arose between the company and its broker-dealer / lead investor regarding the economic value of the warrants embedded in the financing structure and the benefits received through the convertible transaction.
Instruments & Strategy: Convertible bonds, equity warrants, equity, derivative valuation and structured equity financing.
Core Questions:
- Historical review: Reviewed all conversions to assess the quantities and defining features of warrant tranches received by investors. Reviewed how the company’s corporate actions (listings, splits) impacted all instruments.
- Product review: Analyzed the multiple interdependent and atypical clauses in the issuance documents, assessing their risks/benefits for both parties.
- Valuation: Chose the valuation model for the warrants and demonstrated its appropriateness. Extracted and justified historical and implicit volatilities. Valued the different warrant tranches at each critical date in the commercial relationship. Estimated the impacts of the more complex clauses.
- Valuation: Reverse-engineered the bond to calculate its yields at the onset of the transaction, at the critical junctures, as well as its realized yield.
- Damage assessment: Estimated the economic benefits received by the investors.
Our work: The biotech company retained two different Navesink International experts due to the technicity of both the bonds and the warrants. The two experts synchronized their work, the warrant report becoming the basis for the convertible bond report. A rebuttal analysis of the broker-dealer/investor’s report was provided. Navesink experts amended their reports to take advantage of new information then provided.
Outcome:
- Navesink’s analysis demonstrated that the bond yields were usury – at least 267.09% at inception and still 141.20% realized (despite mismanagement). This provided a strong legal argument to our client’s attorney.
- Under NY law, usury loans must be cancelled and all payments returned. The damages were significant.
- The parties immediately settled after the depositions.
- The opposite expert, whose report was of much lower quality, was fired from his (well-known) legal consulting firm.
Testimonial:
“Slugging away on our motion for summary judgment, which is due today, and saved the best for last: plugging in your numbers. Really refreshing to go back through your work and find how clear and comprehensive it is. Thank you both!!!”SVXY options and margin liquidation
Matter type: Arbitration.
Facts: A retail trader was liquidated due to option losses realized in the last two hours of Volmaggedon day.
Instruments & Strategy: SVXY (short-volatility ETP), equity options on those VIX reverse ETFs.
Core Questions:
Loss causation, product complexity and foreseeability, suitability, supervision and margin methodology, and allocation of responsibility.
Our work: We performed a document and quantitative review focused on:
- Loss causation: Reconstructed how short put selling on a short-volatility ETP amplified losses during a volatility jump.
- Product analysis: Explained the mechanics of VIX futures, ETP rebalancing, and why options on a short-volatility ETP can compound tail exposure. The strategy was ‘exotic’ , highly volatile and highly risky.
- Foreseeability: Used professional-grade fat-tailed statistical analysis to show that large volatility shocks are not rare, and should be considered in professional risk management.
- Disclosures: Reviewed the ETP’s offering documents and risk disclosures plainly stating the potential for rapid and substantial losses.
- Suitability: Assessed whether the client’s sophistication matched the strategy, and contrasted it with the broker-dealer’s technical knowledge and supervisory obligations.
- Supervision and margin: Evaluated platform risk models and margin calculations, including whether methodology understated tail risk and whether additional margin or trading restrictions were warranted.
Outcome:
Provided a detailed report and exhibits supporting a defense narrative that the lack of supervisory and deficient margin practices materially contributed to the loss and to the inappropriateness of the broker’s claimed damages.
