Investors - LC / Increase In Applicants With Public Records?
« on: December 31, 2012, 12:00:00 AM »
I don't think we need to do any more research. We've established a major change in the data from week to week. It's time to call LC.

Investors - LC / Increase In Applicants With Public Records?

Here's a table by vintage quarter with the percentage of loans with a public record. Now, these are issued loans, so perhaps a TON of the ones on the platform won't issue, but 46% is so far out of line with the past, it makes me think something's wrong. That said, a public record isn't the end of the world.

Investors - LC / Has LC loan quality dropped?
« on: December 31, 1969, 07:00:00 PM »
I agree on the egg-nog bit.

It's hard to have a clear discussion on the web, as the way one defines the outcomes, makes their data set, and conducts their method has much to do with the results. Often people don't lay that out clearly enough to have a fruitful discussion, or readers gloss over key words that have important meaning.

We should have an in-person conference or workshop! Then we could dig in and have more time to learn from each other.

Investors - LC / FMV of distressed notes
« on: December 18, 2012, 12:00:00 AM »
If anyone has collected information about *which* notes have gone into grace period, late 16-30, and late 30-120, I would be very pleased to do an analysis of them to find out any predictive factors that I can. It's too bad LC doesn't provide this variable in their extracts.

I'm a full-time college administrator and adjunct professor in finance at a medium sized teaching university. In a former life, I was an analyst at the RAND corporation, where I earned my doctorate in policy analysis. I have a baccalaureate in mathematics (pure), and have enjoyed programming for 20 years.

Investors - LC / Public Records on File.. do you ever invest in the note?
« on: December 14, 2012, 12:00:00 AM »
Many of those questions will be answered on my website within a couple weeks. However, I don't really want to give statistics lessons over the net. A few stats courses and you'd have enough knowledge to do what I'm doing.

By the top 10% thing, I mean that I programmed numerous strategies, including filters, and then compared the returns against each other. I used inception to Q2 2008 to train my modeling and tested all strategies on Q3 2008 to Q2 2009 loans. Their outcomes are known at this time.

Public record is just one thing among many that affects the probability of a charge off. An attractive loan along many other dimensions may still be attractive with a public record. I buy them occasionally if the math works out.

Employer is not in any file LC provides. I think some of these websites have been writing screen scrapers to get some extra fields.

Investors - LC / Loan Sizes
« on: December 31, 1969, 07:00:00 PM »
I've always used $50 per note. The way I decide on loans in which to invest doesn't suggest too much advantage in making some notes outsized. They are all very similar performers in expectation.

If I do another large round of funding (I invested 20k in July and August), I will probably bite the bullet and go with $75 just to shave a couple weeks off the investment time.

Investors - LC / Tool to find the default rate on a single note?
« on: November 20, 2012, 12:00:00 AM »
Write a script in your favorite statistics package that loads all the data and allows you to enter a parameter of a loan id, reads the characteristics of that loan, and finds all loans that are within certain tolerances of that loan on as many characteristics as you like. Then output whatever performance metrics you want.

Investors - LC / Loss Mitigation Strategies
« on: November 20, 2012, 12:00:00 AM »
My concern is that this type of information asymmetry probably won't last. You are getting an advantage in the secondary market. At some point the market maker will recognize that this is harmful to their business model long term and fix it so that anyone can look up anything about any loan, including pre-grace period, days "processing," etc.

I'll give you this one for free: there's no relationship.

Defined "double_or_more" to be just as you say: double or more the amount requested vs. the revolving balance, but only defined among credit card refinance or debt consolidation. By the way, it's not that common to request twice as much or more--around 14%.

Filter strategies necessarily restrict loan volume too much. Each characteristic only has a probability of causing no repayment. I come up with a probability of a problem and consider the interest rate, then invest in the top ten percent of a ranked list. Takes two minutes to create a list using programs I developed and a stats package.

Stata for the win. Any stats package will be able to handle this.
