Stochastic Local Volatility Calibrator

The SLV Calibrator is based on the original Ren & Madan paper and follows the implementation as described in the Bloomberg paper "Stochastic Local Volatility" by Tataru & Fisher. The SLV Calibrator takes any calibrated LV surface that matches vanillas. Then, using a non-linear Fokker-Planck equation, one adds a SV component and for any given set of SV parameters computes a new "leveraged local volatility surface" that still matches the vanillas, while accommodating SV. The SLV Calibrator then applies to this PDE solution a Levenberg-Marquardt optimizer and finds the (time bucketed) SV parameters that yield a maximally flat leveraged local volatility surface. At this point you have the pure LV model (the original LV surface) and the pure SV model (the SV parameters that yield a nearly flat leveraged LV surface). Both models fit the vanillas. The SLV Calibrator then solves for a mixing fraction the mixes the two models together either by a) calibrating to selected exotics, or b) using historical data.

Commodity Models

SciComp is pleased to announce a new research paper "Putting Smiles Back to The Futures" that describes a practical method to extend the classical log-normal Gabillon model to incorporate volatility smiles; and a forward market model for pricing options on Forward Freight Agreements (FFA) with a term structure of FFA volatility.

Gabillon Model with Volatility Smiles

The Gabillon model can effectively capture the difference in future curve volatility between the front- and back-ends of the curve. However, the Gabillon model ignores the effects of volatility smiles that are commonly observed in the options markets. Given their dependency on multiple points of the futures curve, the value of many commodity derivatives can be sensitive to the volatility smiles of futures prices. To effectively price and risk manage these products, we need to incorporate smile information into the correlation and term structure modeling of the futures curve.

The Forward Freight Agreement (FFA) option model

The FFA option model is based on the forward freight rate and uses a three-parameter formulation to capture the shape of the instantaneous volatility. The model supports FFA options with multiple settlement periods and automatically calculates the relevant dates of the monthly option strips. The model also calculates various Greeks (e.g., Delta, Gamma, Theta and Vega).

Graphics Processing Units in Computational Finance: Approaching the Mainstream (Strategic Focus), Ovum

"Graphics processing units (GPUs) represent an increasingly performant and cost-effective means of executing complex calculations, and many capital markets participants are running pilots with them for pricing instruments or analyzing their risk profile...

Software vendors and service providers ease GPU adoption

...SciComp's flagship product, SciFinance, delivers code synthesis technology (i.e. software that generates software) for pricing complex derivatives. In essence, this approach masks the complexity of parallel programming from the end user, while leaving them free to define the characteristics of the pricing model that they want to run on GPUs. Users can experiment with different solvers, finite difference schemes, or interpolation methods by changing a few lines in the specification. Specifications can be modified to capture particular instrument features and developer's preferences for mathematical constructs and routines. SciFinance then automatically generates fully documented C/C++/CUDA pricing model source code (currently SciFinance automatically generates CUDA-enabled source code for any Monte Carlo pricing model, with support for PDE pricing models scheduled for release later this year)."

Cozy up with CUDA, Wilmott Magazine

‘CUDA’ is the magic word to direct the newly enhanced SciFinance to CUDA-enable your Monte Carlo pricing models

"...Obviously, speed of model development is important, but so is the execution time of the pricing model. SciComp has partnered with NVIDIA, and we are now taking advantage of their graphics processing unit (GPU) technology. NVIDIA developed a programming language called CUDA that allows you to develop programs that efficiently run on the GPU card. Code that takes advantage of the GPU’s parallelism exhibits tremendous increases in execution speed compared to serial code.

SciFinance can now automatically create CUDA-enabled pricing and risk models, so a customer need only add the keyword ‘CUDA’ to an existing serial model specification. Depending on the type of pricing model, it can run from 30 to 120 times faster than the comparable serial code. One of the best parts from a customer’s perspective is that they do not need to have any CUDA or parallel computing experience, SciFinance takes care of all of that."

The Rubik's Cube of Risk, Risk Magazine

"...Other developers have noted the similarity between calculations underlying graphics processing and risk analysis, and are running their software on the latest graphics boards, which can have four chips each with 240 processors, giving a performance improvement compared with a conventional PC board of around 250 times. Pricing and risk model vendor SciComp, based in Austin, Texas, is among the first to exploit this, modifying its code to run on the processors of California-based graphics hardware specialist Nvidia. "Without this kind of approach, the task of integrated risk management is not doable," says Ponzo.

Solving the Rubik's cube of integrated risk management is going to take a combination of innovation and pragmatism within each mini cube element of risk, as well as across each dimension of the whole."

Wall Street Accelerates Options Analysis with GPU Technology, Wall Street and Technology

The thousands of lines of C or C++ code generated by SciFinance can help a quant produce a new pricing model in a matter of hours, says Randall. "The compiler and the language make the hardware accessible to general programming as opposed to graphics programming," says Randall, who contends that the NVIDIA hardware can enable the code to run 30 to 50 times faster than standard PCs. "Programmers don't have to understand the nuances of how to parallelize code. All of that is done for them automatically."

Tesla 10 & CUDA 2.0: Real-World Applications & Financials: SciComp's SciFinance Beyond3D

"..Traditionally, traders who imagined a deal talked to ‘quants’ (PhDs in mathematics or physics who are specialized in finance) and the mathematical equations they came up with for the pricing model then had to be transformed into a program through weeks of hand-coding. After this error-prone process, the program had to be run to estimate the price.

SciFinance’s approach is to automate program generation; instead of manual coding, the quants can ‘simply’ describe their equations in a specialized language. The process is much quicker and much more reliable. Therefore, the relative length of running the program increases and it becomes more of a bottleneck. The solution they came up with is, of course, FPGAs. Uhhh, wait, no, I meant CUDA obviously:

What may not be as obvious in that image is that the only thing you need to add to get GPGPU acceleration is literally ‘CUDA’; it’s a single keyword, not a fundamentally different way to formulate the math equations. This allows SciComp’s customers to save even more time while also improving accuracy (through a higher number of iterations), both of which result in obvious financial benefits.

The difference between merely being able to demonstrate the acceleration of a basic stock option pricing model and this is huge. The amount of work involved is likely ridiculously higher, and it’s a pretty good example of how much far along CUDA is in terms of software..."

SciComp Accelerates Derivatives Pricing with CUDA, InsideHPC

"...SciComp is one of the first companies to fully embrace the potential that GPUs have in the field of computational finance,” said Andy Keane, general manager of the GPU Computing business at NVIDIA. “The ability to not just deliver small and incremental increases in performance, but instead to deliver 100X and reduce weeks of hand coding to immediate, real-time results is incredibly powerful. We look forward to working closely with SciComp going forward to bring more defining improvements to the SciFinance generated pricing models and in turn their customers’ businesses."

General Monte Carlo Greeks in Practice, Wilmott Magazine

"...The simplest general approach for estimating the Greeks is based on finite differences, in which the Monte Carlo pricing function is called to revalue the derivative at perturbed parameters and a finite difference is applied to approximate the partial derivatives (price sensitivities). The advantage of such estimation lies in its independence of the underlying model and payoff structure, enabling a generic implementation with little additional programming..."
