Nice, but still very important that before making a post like this, you should do some research yourself and get some genuine link to where we can either buy the book or get the pdf version of it.

First - - "What's his insights you talking about" this is the question those who have not read this book would ask you, cus they clearly and genuinely don't know what you are talking about.
Best would have been you quote the authors insight before asking your question.

Secondly - - what is Quant strategy? "you can easily Google that" you might say, but what's wrong if you take your time to explain here for those who don't know what it actually is?

This is how good post is made, and this will not only give your post more exposure, it also adds credibility as you get to get credit for contributing positively to the community through you sharing your knowledge with others.
