If there is one good thing to say about this book, it's probably the author repeated emphasis on the importance of finding and sticking to one's own most comfortable investing style, because swinging between speculative trading (especially day trading) and long-term investing is a recipe for agony, depression, and financial disaster. Admittedly, it is one of the most common issues among how many laymen approach investing. However, overall the book is a mixture of confusing arguments, self promotion, and some investing cliches.
Aside from reiterating the truism that successful investing (or trading) comes from overcoming and control of one's greed and fear, the author, oddly, does not address how exactly to steadily cultivate such a stoic mindset in the face of humans' most primal emotions. Much of the rest of the book is dedicated to short-term trading techniques, particularly reading technical indicators and signals. And yet, in the next chapter, the author remarks that most ordinary investors will likely get burned through such trading. In a similar vein, in one chapter, he talks about how to "predict" future market directions, and then in the next chapter, stresses that top investors succeed mostly not because of their prediction skills, but rather their sophisticated, multi-layered strategies to tackle any scenario. Even the book's English title "The Secret of Being a Top Investor" is more of a misnomer, as the book offers very little insights on how to invest per se (mostly just short-term trading). Such confusion and lack of coherent argument make it much more difficult for readers to parse out any tangible, actionable takeaways, that is, if there is any to be found.
