Do High Frequency Traders Need to be Regulated?

seminar date: 
Thursday, February 18, 2016 - 5:45pm
seminar location: 
Tarun Chordia, Emory University

Stock index exchange traded funds and futures prices respond to macroeconomic announcement surprises within a tenth of a second, with trading intensity increasing ten-fold in the quarter second following the news release. Profits from trading quickly on announcement surprises are relatively small, however, and decline in recent years. Trading profits also decrease with relative quote intensity. The speed of information incorporation increases in recent years and order flow becomes less informative, consistent with prices responding to news directly rather than indirectly through trading. Our evidence is consistent with increasing competition among high frequency traders, which mitigates concerns about their speed advantage.
