Asian and European Option Specifics–Pricing, Estimation, and Comparison in R

— 2021, PDF version, GitHub repository.

Simulated Asset Prices and Asian Option Dependency

Conclusion (excerpt, p. 18):

“In this paper, I propose methods to estimate vanilla and exotic options’ prices and probability of exercise using Monte Carlo simulation in R. The computational efficiency of these methods relies on;

  1. Usage of vectorization, and
  2. Recycling of the simulated geometric Brownian motion paths.

In general, the cumulative average transformation (…) in the Asian option’s pay-off greatly reduces uncertainty as time goes by. This leads to lower variability in the option’s price, delta, and probability of exercise. (…) [The] Asian option’s delta (…) inevitably approaches zero over time, as the underlying’s future prices have continuously less impact on the option’s pay-off.”


Model Implied Asset Pricing Beliefs: An Empirical Analysis for S&P 500 Constituents from 2010–2020

— 2021, PDF version, GitHub repository.

Beta Portfolios Performance Plot

Abstract (excerpt, p. 3):

“In this study, I am deriving explicit and implicit investment hypotheses from the Capital Asset Pricing Model (Sharpe, 1964), the Fama and French 5 Factor Model (Fama and French, 1993), and common price multiples. I empirically investigate the credibility of these investment beliefs using data from S&P 500 constituents from January 2010 to December 2020. The significance of each investment hypothesis is assessed by two methods of statistical evaluation.”

Conclusion (excerpt, p. 32):

“(…) This research found credible statistical evidence in support of the “high GrowthSpread® outperforms low GrowthSpread®”-hypothesis. There is no statistical evidence in favor of any of the remaining eight hypotheses under investigation. When it comes to one-directional portfolios, I found evidence in support of the following statements:

  1. The high GrowthSpread® portfolio significantly outperforms portfolios drawn at random;
  2. The low GrowthSpread® portfolio significantly underperforms portfolios drawn at random;
  3. The low Price-to-Cash Flow portfolio significantly underperforms portfolios drawn at random.

Noteworthy, there is some, but insignificant evidence in support of the low Profitability, high Profitability, small Size, and low Beta portfolios.”


Silver Commodity Market-Timing—A Simple Macroeconomic Pricing Model

— 2021, PDF version, GitHub repository.

Silver Pricing Model Regression Results

In this article, I develop a macroeconomic ‘fair-value’ indicator for the silver spot price.

Conclusion (excerpt, p. 11):

“(…) empirical analysis suggests that the silver spot price is roughly twice as sensitive to changes in USD expected inflation than it is to changes in the 10-year U.S. Treasury rate. When it comes to market-timing, it can be concluded the following:

A Strong Bullish XAG/USD Case:

A Strong Bearish XAG/USD Case:


Forecasting EUR/USD Volatility Using Supervised Learning

— 2020, PDF version, GitHub repository.

Volatility Forecasts with Different Supervised Methods

Conclusion (excerpt, pp. 19-20):

“When it comes to predicting financial volatility,

  1. During ‘normal’ times, the support vector machine algorithm with linear kernel outperforms all other considered methods. This is confirmed by two out-of-sample datasets (…);
  2. During periods of market turmoil, the gradient boosted tree algorithm outperforms all other considered methods. This is confirmed by the complete validation set which is heavily impacted by turbulence surrounding the Covid-19 pandemic.

The self-developed linear weekday effect model improves over the HAR-RV model by Corsi (2009). It performs second best during ‘normal’ and ‘crisis’ times, respectively. The absence of any tuning parameters and the apparent robustness across market conditions makes this model a well-suited candidate for applications in practice.

Noteworthy, in the appendix, it is found that the industry-prevalent GARCH(1,1) model is outperformed by all models considered.”
