Adventure: Master in "Computational Finance"
From January, 2000 to December, 2000, I was a student in the
Computational Finance Master's
program of
The Oregon Graduate Institute of Science and Technology
(OGI).
I was awarded the M.S. degree in Computational
Finance in February 22, 2001.
During my studies in Computational Finance,
I was able to apply already familiar analytical and numerical
techniques in areas of quantitative finance
ranging from Derivative
Pricing to Risk Management. The work at Oregon also involved
the
application of Monte Carlo and Bootstrapping methodologies to quantify
the so called Value-at-Risk (VaR) of financial instruments.
We implemented and compared different approaches to price Derivatives
including
Monte Carlo,
Finite Difference, Binomial and Trinomial Tree Methods. I also
have the opportunity to learn and extensively explore the applicability
of Times Series Analysis
to Financial Market Forecasting, including volatility prediction via GARCH
modeling. In addition, during my last term in the Computational Finance
program, I participated on a
research attempting the application of a statistical technique known as
Independent Component Analysis
(ICA)
to analyze the interaction and
term
structure of some of the indexes that comprise the iShares MSCI
Index Funds.
More specifically,
course work experience in Computational Finance program includes
-
Financial Time Series Analysis (emphasizing GARCH
modeling in financial forecasting and volatility prediction).
-
Advanced Numerical Computing in Finance (emphasizing
analysis of stochastic differential equations and
the pricing of derivatives via Finite Difference, Monte Carlo,
Binomial and Trinomial Tree methods).
-
Risk Management (emphasizing Value-at-Risk
(VaR) computational models, including Historical, Monte
Carlo, Del-Normal, and Bootstrapping methodologies.
-
Other related courses include
Options and Futures I and II, and
Investment and Portfolio Management
This
stage of my education allows me to enhance, strength and became very
knowledgeable on a variety of computer software and programming
languages including, C,C++,Matlab,Splus,
and PERL. I also acquired a working knowledge on BARRA,
a well know financial software.
Following are some interesting projects I participated during my
adventure in Computational Finance:
Projects
-
Relevant Team projects:
-
Built an optimal portfolio based on
dot com companies, and computed its VaR
using Historical,
Monte Carlo, Delta-Normal, and Bootstrapping techniques.
Optimization was performed using Matlab optimization
functions and Differential Evolution constrained on
minimizing risk, maximizing return, and maximizing a
defined profitability function.
-
Presented a
BARRA CASE STUDY showing the
benefits of Diversification as a way of controlling
investment risk exposures.
-
Analyzed and presented the paper
"The Distribution of Stock Return Volatility" by
Andersen, T. G., Bollerslev, T., Diebold, F.X., and Ebens, H. (1999).
-
Relevant Individual project:
-
Wrote a C++ code to price
Asian (put and call) Options
via Monte Carlo simulation
using geometrical
and arithmetical averages. The program also reports the
corresponding
confidence interval based on the
Student-t distribution. A Text User Interface
was also written.
-
Built and maintained a support web site
(
http://www.cse.ogi.edu/class/cse570/)
for the course
Principles of Modern Finance
(CSE570). Associated with this page there is a
Discussion Board I maintained for tutoring and help
students of CSE570 with the Matlab assignments.
-
Analyzed and presented the paper
"The Noise Trader Approach to Finance" by
Shleifer, A. and Summers, L.H.,
Journal of Economic Perspectives(1990),
Vol. 4, number 2, (19-33).
