| Tiivistelmä: | This research paper investigates how fragmentation is affecting market quality in US equity markets. Trade reporting facilities (TRFs) data is used to measure fragmentation, and a variety of empirical approaches are used to compare execution quality and efficiency of stocks with more and less fragmented trading. It is found that fragmentation affects all stocks; more fragmented stocks have lower transactions costs and faster execution speeds; and fragmentation is related to higher short-term volatility but greater market efficiency, in that prices are closer to being a random walk. |
