To be clear, when you say AQR is primarily a "high frequency" firm, do you mean they are mostly position neutral with execution in (at most) a few microseconds?

I do not think HFT has a very clear definition anyways. I'm pretty sure most we hear of comes from regulatory cases/exposure.

This is how the SEC characterizes HFT firms.

1. Use of extraordinarily high speed and sophisticated programs for generating, routing, and executing orders.

2. Use of co-location services and individual data feeds offered by exchanges and others to minimize network and other latencies.

3. Very short time-frames for establishing and liquidating positions.

4. Submission of numerous orders that are cancelled shortly after submission.

5. Ending the trading day in as close to a flat position as possible (that is, not carrying significant, unhedged positions overnight).
