Implementing Black Scholes in Providing Easily-Accessed Objective Stock Predictions Nihaar Sinha

Abstract This project investigates creating an application that downloads stock information from the Internet and applies to it the famous Black Scholes algorithm, outputting the result. The Black Scholes algorithm is used in modeling price variaton over time of securities that are heavily traded. This application prompts the user for one of several available heavily traded stocks, pulls that stock's information from the Internet, and applies the Black Scholes algorithm to it. The goal of this project is to create an easy to use application that gives the user not just stock information but to an extent objective stock advice.

What is Black-Scholes? Black-Scholes is a mathematical model of price variation Heavily traded assets follow geometric Brownian motion Constant drift and velocity of these assets One of the most famous financial processes

Brownian Motion http://www.alexfb.com/twiki/pub/PtPhysics/WebHome/bm2.png

Similar Research There have been many modifications to Black- Scholes Preetam D’Souza investigated Geometric Brownian Motion last year This project is practical, not theoretical

Reading in Data Source code is imported from the Internet Data is parsed for keywords Last Trade: “</small><big><b><span id="yfs_l10_ibm"> P/E :“</span>:</th><td class="yfnc_tabledata1">

Reading in Data (cont.) Parsing data means source must be permanent Source utilized is Yahoo! Finance Snapshot of what the Yahoo! Finance interface looks like http://finance.yahoo.com/q?s=IBM

Multiple Stocks User will be able to pick from selection the stock User is only prompted for stock symbol Import URL is thusly customized

Class Structure The Main method prompts for the stock symbol and imports the data Main method also calls for the Black-Scholes implementation The Black-Scholes class calculates the price Black-Scholes class also returns the result Result is outputted in the Main method

Problems Run Into How exactly to parse through all the data and find the relevant information How to organize the program to make it less cluttered How to prompt for user input How to code the Black-Scholes algorithm

Solutions After inspecting the source, relevant data is always followed by a specific tag User prompted for information through JDialog boxes Black-Scholes algorithm to be coded fully in separate parts

How has my hypothesis changed? Focus has shifted from modifying Black-Scholes to applying it in practical use Concentration on mobile applications has inspired need for concise code and very user-friendly GUI’s Testing has shown that the best way to import data is through importing the source code and not trying to download files
