For all the criticism the book has received, I liked and enjoyed it. It illuminates a poorly understand segment of the financial world, namely high-frequency trading, and outlines some of the zero- and negative-sum games in that world. The stories and the writing are very good, as you might expect.
It is a mistake to take the book as a balanced or accurate net assessment of HFT, but reading through the text I never saw a passage where Lewis claimed to offer that. Maybe the real objections are to be lodged against the 60 Minutes coverage of the book (which I have not seen).
Why not read a fun book on a fun and understudied topic? Just don’t confuse the emotional tenor of the stories with a final and well-reasoned attitude toward the phenomenon more generally. Surely you are all able to draw that distinction. Right?
