Idle ramblings of a wandering mind...

I have not posted anything here for a while as I have been busy trying to give shape to my dissertation. As part of my research I have been working with Lending, Borrowing and Loan Repayment Data at Prosper.com and there are some pretty neat results. I finished writing an article about my results and submitted it to one of the major Information Systems conferences AMCIS (Americas Conference on Information Systems) for review. I of course can not detail all the results here as it is under review, here is the abstract of the paper I submitted:

Peer to peer financial marketplaces provide a platform for individual lenders and borrowers to interact and transact. These marketplaces dis-intermediate the traditional financial services business models. In this exploratory paper we study the operation and effectiveness of one such marketplace: Prosper.com. We analyze six months of lender, borrower and loan repayment data to answer preliminary research questions about lender behavior, market effectiveness and antecedents of loan default. We show that lenders mostly behave rationally and charge appropriate risk premiums for antecedents of loan default. We also show that there are mismatches between risk premiums charged and relative importance of factors that drive loan default. We then explore the dynamic process of lenders adjusting their lending strategies to reduce these mismatches. Interestingly, our results indicate that the group reputation used in marketplace is not effective and needs to be enhanced. Our analysis provides a base for future research in this exciting and evolving context. Our results provide directions for practice applications as well as future research in design of financial marketplaces, investing and risk mitigation strategies and improving effectiveness of financial marketplaces.

I am excited about my research on Prosper.com (or Peer to Peer Financial Marketplaces - the name I have given to the broader phenomenon). I am continuing to enhance my analysis and looking for improving my paper and submitting to a top journal. If you would like to read a copy of my paper then pls drop a comment with your email and I will send one to you.

It seems my research will be quoted in the SmartMoney Magazine. Ann Kadet, who is a columnist and Senior Editor with the magazine got in touch with me about my research on Prosper.com. The coming issue of SmartMoney will have an article on Prosper.com and according to Ann, there will be a mention of my work. Cool...

Portfolio Update

Like everyone else, my stock portfolio also took a hit in last two weeks with the sharp decline in US markets. Although, I continue to believe that in the medium term stocks are worth keeping - so I used the drop to add to my holdings and I have now mostly recovered. My current major holdings are (in order of size of holding): STX, AMD, TTM, TNE, UL, FTE, SCSS, CX, CAT, IBN, TTMI, HMC and TKC. As you can see - I have diversified considerably - I now have large technology MNCs, Indian Auto, Brazilian Telecom, Mexican Cement, Consumer Goods, Global Auto, Turkish Telecom and some good old US companies in my portfolio... Before the Feb end decline, I had booked profits to the tune of some 16% return - not bad for a two month period.

Research Update

Since I wrote last one of my papers was nominated for the best paper award at HICSS 2007 (Hawaii International Conference on Systems Sciences). The paper is available here. I have further improved this paper and it is now going to be a part of my dissertation.
