group 9 : Clustering with correlation coefficient

This presentation / project is about correlation coefficients used as the clustering measure.

File needed to see the correlation coefficients and bi-monthly returns:

returnAstcBiMonthlyEG1.mat

Address in the presentation the following:

1) Given correlation coefficient from https://mathworld.wolfram.com/CorrelationCoefficient.html

A) What is the meaning of correlation coefficient between the two set of stocks prices?

B) Show why the correlation coefficient between the set of prices A and set of prices B is the same as the correlation coefficient between the set of prices B and set of prices A.

2) After loading returnAstcBiMonthlyEG1.mat in Octave, you’ll have stocks with bi-monthly returns of above 0.009 : 

CC -> correlation coefficients between the stock returns,

RTRS ->  bi-monthly returns (rows) for 412 stocks (columns)

A) Comment the correlation coefficients based on bi-monthly returns among 412 stocks shown in the figure  P5_CC_eg1.pdf

B) Assuming that clusters are created by putting all the stocks whose correlation coefficients among all the pairs are greater than 0.5, comment on the following cluster distribution : 302 clusters with only 1 stock,  28 with 2 stock,  6 with 3,  4 with 4, 1 with 5,  1 with 6 , and  1 cluster with 9 stocks in it.

C) Explain why it would be good to pick just one stock from the cluster for the diversified portfolio.

Chapter 2

1. For apps to be featured on the iPhone, developers must build it with Apple’s software development kit and then apply for approval. Apple rejected the Google Voice iPhone App, and further stated that it would not accept any applications that incorporated Google Voice functionality. Apple reasoned that this app duplicates the phone’s core features. It also rejected Google’s location-based app Google Latitude. If you were developing a collaborative platform, do you think the best model is this collaborative model, or is the open innovation model better – if your main goal is to maximize innovation? What if your main goal is to make money?

Chapter 3
2.Plaintiffs filed a class action lawsuit against investment banks alleging that they inflated prices on more than 300 IPOs, causing IPO investors to overpay for stock, and unlawfully benefited these banks through overcompensation of banking commissions and profits made through quick sales of this stock in their own accounts before prices settled into a more realistic valuation. How would you combat such abuses going forward?
