Patrick O'Shaughnessy Interviews Macro Trader Paul Tudor Jones

Patrick O'Shaughnessy Interviews Macro Trader Paul Tudor Jones▶

Patrick O'Shaughnessy announces a podcast interview with Paul Tudor Jones, covering his market calls, his view that today's market resembles 2000, his case for long dollar-yen and Bitcoin as an inflation hedge, and his daily trading routine.

My guest today is Paul Tudor Jones (@ptj_official), one of the greatest macro traders of all time.

He correctly predicted the 1987 stock market crash and shorted the Japanese bubble in 1990. For over 40 years, his flagship fund has had a negative correlation to the S&P 500. 100% of his returns are alpha.

He says today's market has so many similarities to 2000, "the easiest bear market I've ever seen in my whole life."

He makes the case for going long dollar-yen, why Bitcoin beats gold as an inflation hedge, and why he was wrong about Warren Buffett.

But what I'll remember most from this conversation is Paul's zest for life. He's 71 and still wakes at 2:30 every morning to trade the London open. He works out for two hours a day. He walks with his wife every evening. He travels the country chasing peak spring and peak fall. He's so excited about the songs picked for his funeral that he wishes he could be there to hear them.

Paul has lived five lifetimes in one. He's one of the most entertaining and interesting people I've met, and the conversation will leave you searching to be as passionate about what you do as he is about what he does.

Enjoy!
