In this short article, I explain that the emergence of high-frequency trading firms comes from the increasing fragmentation of financial markets since the early 1990's. I also summarize the advantages and disadvantages of high-frequency trading, which have been identified in the empirical literature. I then define the role played by these high-frequency trading firms during the 'flash crash' on Thursday May 6, 2010. I conclude by underlying that automated trading does not necessarily lead to worsening market conditions, given the animal spirits of traditional investors in stressful periods.
