Invest Like John Griffin – Blue Ridge Capital

If you had to name the top 5 best hedge fund managers ever, Julian Robertson would certainly be on the list. (He's also from Salisbury, NC which is pretty close to where I grew up in Winston-Salem, and there is a book written about him titled, Julian Robertson: A Tiger in the Land of Bulls and Bears.)...

Gene Therapy Comes of Age?

I started out my undergraduate at the University of Virginia in Aerospace Engineering. After a year or so in that track (and a summer internship at Lockheed where all I did was play on the corporate softball team), I decided that aerospace was definitely not for me. (My childhood astronaut fantasies certainly were not the same as...

In a recent review, CXO takes a look at a Andrew Lo paper titled, Financial Econometrics. An interesting aside, here is the book(s) that forever altered Lo's college career choice towards economics. :Paul Samuelson's...

100th Post, Tally Ho!

It has been slightly more than 5 months since I started my blogging experiment, and today is officially my 100th post! (It certainly feels much longer than that.) It is a bit surreal to be in a London cafe right now, having just polished off some of the best dim sum I have ever had after watching my...
