THE POWER OF STORY, by Jim Loehr, reading notes

THE POWER OF STORY, Rewrite your destiny in business and in life, Jim Loehr

A rather remarkable book we stumbled across not long ago. Here are some salient quotes for your consideration.

Story is everywhere. Your body tells a story. The smile or frown on your face, your shoulders thrust back in confidence or slumped roundly in despair, the liveliness or fatigue in your gait, the sparkle of hope and joy in your eyes or the blank stare, your fitness, the size of your gut, the tone and strength of your physical being, your overall presentation – those are all part of your story. P 7

The most important story you will ever tell about yourself is the story you tell to yourself. P 14

If an idiot were to tell you the same story every day for a year, you would end by believing it. p 15

Jot down 10 moments of joy you had in the last 30 days. P 32

I want to be sunshine. (vis-à-vis no. 1 tennis player in the world) -- importance of choosing the right goal. p 50

When Steve B., the man at the start of this chapter who seemed to have it all, recognized, at age fifty-three, the fundamental flaw in his story – that his private voice was not his own but his father’s, that for decades he hadn’t really lived his own life, that he had experienced so little joy in a life that should have been overflowing with it – he broke down. P 106

Book review: Can Wall Street "Quants" make a comeback? WSJ reporter/author Patterson tells how

The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It,

by Wall Street Journal reporter Scott Patterson, is the inside baseball story of the quest for The Truth on Wall Street. That is, the fountain of money that never stops flowing.

-- As made manifest from the odds, the probabilities.

-- As interpreted by the "quants," traders who believe (or believed), above all else, in the numbers, data, statistics.

And why not? That's not immediately pejorative, though Wall Street has gotten a very, very bad reputation of late.

After all, odds, probabilities, are the stuff of everyday life.

We don't think about them consciously. But they're there.

You and I cross the street -- now -- because we see the odds of getting hit are nil. We didn't cross 10 seconds ago because we saw two semi's roaring towards us. We don't even think about these as "probabilities," per se. But they are.

And for those who do think about probabilities, and in connection with financial markets, from a vast resource of education (preferably Phd) and erudition and experience, the rewards can be staggering, as in a million per minute.

Quant trading started in -- wait for it -- Las Vegas, where odds-making (not image, sorry Andre, our favorite LV homeboy) is everything. This is where card counting got its start. Card counting is just probability analysis, on the fly. And card-counting, writ large, is quant trading.

Card counting pioneer, Ed Thorp, was the progenitor of quant trading. (He is the comeback story here, read on......)

Thorp begat Ken Griffin, Citadel. And on and on it went (and goes).

Some of the other featured players here include:

• Cliff Asness, Goldman Sachs, Global Alpha, group leader, and founder AQR


• Boaz Weinstein, Deutsch Bank
  


• Peter Muller, Morgan Stanley
  

Author Patterson wields a deft pen, and never fails to grab the reader at the end of a section or chapter: you have to keep reading. Very entertaining.

To peel back the layers of secrecy and expose the histories, successes, failures, personal peccadilloes -- the whole story of 'the quants' -- is a very great journalistic accomplishment.

Just a very few interesting factoids the author presents:

• p. 63 "In 1991, a company asked Thorp to look over its investment portfolio.....it took Thorp about a day to realize the fund was a fraud." The fund manager? Bernard Madoff.
• p. 68 Thorp's, and later Griffin's, specialty de la maison: buying underpriced warrants and hedging by shorting the stock. That was the start for the financial powerhouse Citadel.
• p. 298 "When (PIMCO chief Bill Gross) was 53, he decided to run a series of marathons -- 5 in 5 days. On the 5th day, his kidney ruptured. He saw blood streaming down his leg. But Gross didn't stop. he finished the race, collapsing into a waiting ambulance past the finish line."

There are many, many more.

THE QUANTS is not an indictment, per se, of the entire enterprise of quantitative trading, but does indict extreme leverage and the perils it presents.

The industry can make a comeback from its meltdown -- if it forsakes excess leverage, according the author. Patterson follows the first quant profiled and author of "Beat the Dealer" and "Beat the Market", Ed Thorp, who turns away from over-leverage, and generates excellent returns without it. (p. 300 -- System X, no leverage, 18% return 2008, on $36 million. This, during a period when Citadel "coughed up half its money, a year in which AQR fell more than 40%, and Saba lost nearly $2 billion.")

So, as per usual with Wall Street, we come back to the question of greed. Greed is good? Maybe like alcohol or fire or nuclear energy? A little bit, the right place, the right time. Managed. To overdo here is to destroy, and the problem is, we're all on the hook for it. THE QUANTS is big, intriguing, messy, clear, ambiguous, and provocative -- just like the financial industry it covers. It is, quite simply, a must read.


PS: Talk about "destroying Wall Street", as we were reading this volume, the Dow experienced the infamous May 6, 2010, "Flash Crash," for which many explanations have been offered, but the truth? We are still waiting; Wall Street doesn't tell all its secrets, not even to Mr.Patterson. As author Patterson wraps it up: "here come the quants."

Indeed.

PPS We received from a Chicago quant this youtube.com
video. Another cautionary quant tale, a good one, told in
large part by a quant-turned-oysterman (he lives off his interest) and
we recommend it to you:

Quotable:

• "Beauty is the right level of complexity."
  
  


• "Condensing 300 pages of prose to one equation = beauty to a mathematician."
  
  


• "A major rethink is required if the world is to avoid a major mathematician-led market meltdown."
