writes "The Harvard Business Review is running a fascinating article on how finance is increasingly abstracting itself — and the gains it makes — away from the creation of value in the real world, and how High Frequency Trading is the most extreme version of this phenomenon yet. From the article: High frequency trading is a different phenomenon from the increasing focus on short term returns by human investors. But they’re borne from a similar mindset: one in which financial returns are the priority, independent of whether they’re associated with something innovative or useful in the real world. What Lewis’s book demonstrated to me isn’t just how “bad” HFTs are per se, but rather, what happens when finance keeps walking down the path it seems to be set on — a path that involves abstracting itself from the creation of real-world value. The final destination? It will enter a world entirely of its own — a world in which it is fighting to capture value that is completely independent of whether any is created in the first place."
