I never read "How to Trade in Stocks" - but I looked it up - thanks. Interesting quote from it:

"The only area I may have differed from most speculators, was when I felt I was truly right, dead right, for-damn-sure right-then I would go all the way, shoot the works."

Reminiscences of a Stock Operator by Edwin Lefèvre. I am trying to remember - was Livermore just a pen name?

I do understand his key techniques of trend following/momentum, reversion to the mean, breakouts. However, I have read enough research material too that concludes that stocks tend to misbehave in TA terms. Otherwise everyone could profit, which is impossible.

But I don't believe in the efficient market at all - that idea is ridiculous to me.

I was skinned too often by penny stocks. So I settled into fundamentals. Now I add some TA on top, but I'm based on fundamentals.
