40. Derivative Hedging On-Demand

41. Equity On-Demand Hedge-funds and investment banks that develop these type of tools to capture mispricings in equity derivatives markets keep them proprietary and do not share with them anyone. The KDS option model and trading platform, also known as EOD, tackles all of these challenges and makes the proper tools available for traders so that they can profit from mispricings everyday! The EOD allows traders to wake up in the morning with trading strategies that are indifferent to whether the market is bullish or bearish. Instead, they can focus on profiting using high probabilities in both up and down markets. This eliminates trading based on human emotion, which is the cause for most financial mistakes! The Bullish vs. Bearish paradigm was created by the Technical Model mindset. Using volatility based analysis and high-probability trading means that the so-called “Bullish” or “Bearish” trade is no longer meaningful, and profitability does not depend on the direction of the market! In this presentation, we will cover the different parts of the EOD system, describe how to use the system, and most importantly show how to execute trading strategies and make money consistently using the EOD.

42. EOD Option Pricing • EOD platform utilizes advanced option pricing models. • Based on trader’s “Risk Appetite,” he or she can use EOD to create trading strategies such as: • High Probability Mean Reversion strategies • Time decay (Theta) strategies • Spread based strategies (vertical/calendar spreads) • Underlying ETF buy/sell strategies • “Risk Appetite” is based on confidence levels, or probability ranges, that are used for mean-reversion trades and also allow traders to tweak their risk tolerance using precise metrics. • For example, a confidence level gives the trader ability to know the exact probability that a buyer of an option will exercise, at any given time. This is very important for HPMR trades! • EOD successfully eliminates subjectivity from options trading by specifying strike price targets and buy/sell thresholds.

43. Pricing Methodologies • Our underlying option models use advanced techniques from quantum physics and nonlinear mathematics, applied to financial analysis and trading. • The models are applied to finance using fundamental laws of physics and mathematics, and utilize coordinate transformations in Space, Time, Force, Momentum, and Energy. • Since option prices have diffusion properties, we can use systems of partial differential equations to model price behavior. • We model the randomness observed in prices and volatilities by using stochastic frameworks such as Variance Gamma and Long-Range Stochastic Volatility (discussed later). • Since solutions to these stochastic and highly nonlinear system of PDE’s are unsolvable via analytical methods, we must utilize massive parallel-processing computational power to run extremely large numbers of scenarios at infinitesimal (intra-day) time steps.

44. Pricing Methodologies • REAL-TIME probability distributions of option prices, as well as REAL-TIME option chains pricing solutions, are calculated through evaluating the large number of intra-day scenarios. • Unlike EOD, most option pricing models in the market-place use Black-Scholes-Merton (BSM) framework as the underlying theory. • There are many problems with using this BSM framework to do real-time options trading, most importantly: • Probability distributions do not have FAT-TAILS as observed in the markets. • Prices utilize a single volatility, which is clearly not true in reality. • BSM framework does not have ability to imply a Volatility Skew or Volatility Smile. • BSM framework was created for European-style options which can only be exercised at maturity. In reality, most ETFs that trade on exchanges are American-style, which can be exercised any time. • There is no ability to capture and quantify JUMPS (both up and down) in prices of options and underlying Equity Index/ETF. • BSM Equations were designed by professors (not traders) to allow “analytical solutions” for their convenience. In practice, we don’t care about elegant “analytical solutions” if the prices are WRONG!

45. American Short-Range Jump Diffusion Model: 100K Pricing Paths for IWM (iShares Russell 2000 Index)

46. Volatility Surface Smile: TZA vs. TNA • The volatility surface of the inverse 3x leverage TZA compared against the positive 3x leverage TNA indicates an inverse relationship. • However, the relationship is not precisely inverse due to the fact that both TZA and TNA are separate tradable securities, with unique option chain dynamics. • Therefore, we are able to capture not only the intrinsic inverse relationship, but also the individual supply/demand dynamics for each ETF.

47. Volatility of Volatility (VXX Surface)

48. American Short-Range Jump Diffusion Model • In addition to Stochastic Volatility, the VGSV based framework enables us to price options using American exercisability. • The American exercise feature utilizes a Least-Squares Monte Carlo (LSM) methodology which iteratively quantifies the probability of exercise PER timestep. • VGSV framework also allows us to model the Jump up and Jump down impact under a Short-Range (i.e. intra-day) time period. • Jump processes are modeled via the sampling of gamma and exponential distribution variates over a large number of paths and trajectories. • For these reasons, we also refer to our option pricing model as the American Short-Range Jump diffusion (ASD) model. • For the long-range (20+ days) option chains, we utilize the America Long-Range Jump diffusion (ALD) model which allows us to capture the longer term convergence properties of option pricing.

49. Fat-Tail Distributions • EOD uses proprietary methods based around Short-Range Variance Gamma stochastic volatility (VGSV) and Long-Range stochastic volatility models. • Within our framework, we are able to produce probability distributions that accurately capture the FAT-TAILS (left and right) implied by the market. • Since most of the mispricings (i.e. Money-Making Opportunities) exist near the TAILS of the distribution (OTM options), precisely capturing fat-tails is VERY IMPORTANT! • The REAL-TIME display of the probability distributions (“Histograms”) allows traders to not only see the fat-tails, but also track how the area under the fat-tails is shifting in REAL-TIME. • Having this fat-tail probability distribution framework allows us to effectively DISCOVER the market inefficiencies throughout the trading day.

50. Interest Rate Model • Three-Factor BGM/Libor Market Model (LMM) • Forward curve calibrated to a daily mixture of Libor, Euro$ Futures, Euro$ futures options, and intermediate to long term swap rates • Volatility calibrated to daily end-of-market swaption volatility surface • The “battle tested” forward curves for trading & valuations are guaranteed with the maximum smoothness.
