About 'The Impact of High-Frequency Trading on Financial Markets'

Over the past decade the rise of automated trading has transformed financial markets. Nowadays, a large part of trading volume can be attributed to high-frequency traders that receive a considerable amount of attention from regulators such as the SEC and media. Part of this attention stems from the continuously growing list of incidents involving high-frequency trading. The most famous incident is, without doubt, the Flash Crash of May 6, 2010. The research presented in this thesis contributes to the knowledge about high-frequency trading by (1) providing a detailed overview of stylized facts of the new trading environment, (2) investigating the importance of trading speed for the profitability of technical and news-based trading strategies, (3) analyzing the effect of high-frequency trading on market quality measures, such as volatility and liquidity, and (4) examining the effect of high-frequency trading on IPO underpricing and market quality on the first trading day of a stock. The results show that trading speed has a significant statistical and economic impact on profitability, especially during macroeconomic news announcements. Furthermore, the effect of an increase in high-frequency trading activity on market quality is mixed, with both positive and negative relations, depending on the market quality and algorithmic trading proxy under consideration.
