Via the Manual of Ideas blog. Here is Buffett on manager selection:
But I don’t know many of the newer investors, they’re not my contemporaries. It’s not enough to just look at track records. They aren’t predictive and there will always be a few people that do well. I know guys who can make 50% a year with $5 million, but not with $1 billion. The problem with guys that do well is they attract so much money that it neutralizes their advantage. It’s hard to identify them, and even harder to make a deal to keep them from attracting other capital. It’s like betting on a 12 year old horse that won at 3 years old. It’s also important to avoid managers who use leverage. It’s the reason that investors with 160 IQs flame out.
