If you had read Livermore, the guy’s puzzled too.
Let me quote an excerpt from Richard Smitten’s How to Trade Like Jesse Livermore

Livermore believed that the game of speculation is the most uniformly fascinating
game in the world. But it is not a game for the stupid, the mentally lazy, or the person of inferior emotional balance, or for the get-rich-quick adventurer. They will die poor.
There is a very true adage that Livermore loved: “You can beat a horse race, but you can’t beat the races.”
So it is with market operations. There are times when money can be made investing and speculating in stocks, but money cannot consistently be made by trading every day or every week during the year. Only the foolhardy will try it.
