Worldly Wisdom and Mental Models

Charles Munger's 1994 USC Business School speech on Worldly Wisdom and Mental Models.

Blackstone IPO

It's clear that Chinese government has not got the return it had expected in Blackstone's IPO. To be fair, 80% of the investment universe would have guessed the other way.

The long term return on that investment would largely depends on how the tax bill unfolds and how long the favourable borrowing environment persist.

Investments made in the other way are generally more successful. For example, Goldman's 5% stake in ICBC and BOA's 10% investment in China Construction Bank

How to price CDS Indices

A good introduction on how to price CDS indices (a basket of single name CDSes). And here is the link to the spread sheet.

Of course, you can always use the average of single name CDS spreads as a first order approximation, which ignores the spread convexity. The proper method, as presented in the spread sheet, is risky annuity/DV01 weighted average of these spreads.

Interviews with Mohnish Pabrai

Microsoft .NET StockTrader

Microsoft just released .NET StockTrader, an end-to-end sample trading solution, at SIFMA.

The application and its source code are not yet available for download. Judging from its technical overview paper, the design is a very standard n-tier, SOA solution:

• Web Application Layer (UI), utilizing ASP.NET and Web Forms
• Middle layer Business Services Layer (BSL), utilizing stateless C# classes
• Data Access Layer (DAL), utilizing ADO.NET and stateless C# classes

The design focus is on the business layer, with WCF based webservices implementation (transaction processing, interoperability, scalability, etc).

Microsoft has not put any of the cool stuff (such as WPF or SilverLight) to spice up the presentation layer, neither has it pushed the bleeding edge data access technologies (DLinq, Linq to Entities, etc).

Design Principle Acronyms

• A rather cynical list of acronyms in software engineering. My favorites are ADD, CYAE and GMPM...
• Okay, seriously, here is the REAL list of design principles you should follow (including OCP, LSP, DI, etc).

The beauty of acronyms is that they make you look incredibly professional in the eyes of non-professionals when you talk like this:

"Lad, YAGNI, so KISS and DRY"...

The Essays of Warren Buffett

This book is essentially a collection of Warren Buffett's letters to BERKSHIRE HATHAWAY shareholders in the last thirty odd years. The book organizes these letters in such a way that the paragraphs addressing the same topic are clustered togather, make reading much easier. If you have absolutely too much time to kill, you can read pretty much all of it here.

The book is a fun read and many ideas from the "value investing" (a term that's redudant according to Warren Buffett) master are simply brilliant. I particularly enjoyed his critics on EMH:

"What could be more advantageous in an intellectual contest--whether it be chess, bridge, or stock selection--than to have opponents who have been taught that thinking is a waste of energy?"

I think B-schools should give more weights to this type of thinking when teaching modern portfolio theories. This should not be completely off the chart given that we are still debating whether to teach both the Bible and Nature Evolution in high schools...

Gamer Generation

Koreans have actually made a profession out of Starcraft. You should see it in Gamer Generation on Discovery Channel. These players are treated like, for the lack of a better word, heroes.

I still remember how crazy we were playing Starcraft on the homemade rudimentary intranet in the dorms back in college years back. If you do a regression on one's GPA with his Starcraft winning record, the negative coefficient would be statistically significant at any confidence level --- not that it matters much though, according to Gamer Generation, the pro players in Korean owes a handsome salary. And even at the end of their career in their late 20s, they are hired by financial firms as stock brokers (might be traders, I suspect)...
