Peter Vig, Founder and Portfolio Manager of RoundRock Capital Partners LP, who worked with Julian Robertson at Tiger Management on his energy holdings :
“Julian taught us how to get these short ideas, taught us to be sensitive to short term price movements on stocks. What he had, which was unusual, was the ability to go flip a position from long to short: if you were long the stock you should know what every expectation in the market is baked into the stock price. As a well informed investor in the specific company you should know when there is an anomaly in the expectations on margins or other metrics, and take advantage of that anomaly. Not just sell the long position, but go from long to short.”
