SOHO is a fictionalized account of a person's life up to his mid-40's. Unless you've also read the Sarnoff book, based on independent research about the real person and not these Richard Smitten lovey/dovey "family ties" related books, it's easy to be misled by what Livermore actually did vs. what others said he did. He was a total news hound, embellishing any big play he was involved in to make it seem as though he had a magic touch. He didn't, but it helped to attract more money for him to, ahem, "manage". He won big, lost big and spent the majority of gains he ever made like a sailor on perpetual leave in Bangkok. He hung around the rich in their social playgrounds so he could either get their big trading ideas or what was going on in the manipulation world. It was a very different time and place (pre-1930) than the markets we see today...the land of no SEC.
Let's face it, 1906 was a complete luck-out fortune made because of the San Fran earthquake. Livermore was being financially backed (NOT a "lone hand", by the way) and he was totally against the ropes on his Union Pacific short when serendipity intervened. Now, who wouldn't rather hear of the SOHO account of the New Jersey boardwalk vacation stroll to the broker's office out of sheer boredom story than the reality of Livermore being a hair's breath from having his b@lls nailed to a fence post on the next short squeeze? I'll go for a re-read of the SOHO story any day of the week! It's fiction and fiction loves to play with your imagination.
I'm not disputing the fundamental principles of trend following as laid out in SOHO or that Livermore was a fake in the sense that he never made millions at any given time in his career. I'm saying that most of Livermore's success came from (now) illegal manipulations of the market. It's not hard to look like a market genius when you have a large pool of shares tied up in a stock of that era and you're pretty much calling all the zigs and zags because of the size you're swinging around.
The most important thing you can do to keep your head straight when you hear 'this story' or 'that story' about other people's successes in life is to trust that Occam's Razor is about the closest thing you'll get to the truth without knowing all of the facts firsthand.
