Market-neutral strategies such as pairs trading and merger arbitrage have become increasingly important over the past few decades, yet the literature on them is relatively undeveloped. There are simulation studies which imply theoretical profits, but little empirical work has been done on the actual trading because it is so difficult when trades are anonymous. I describe a technique of "time difference analysis" for studying financial data which is complementary to "time series analysis" and enables empirical inference of pairs trading in two securities. Related trading indicators are computed by analyzing the distribution functions of the time differences between trades, and performance is confirmed by identifying pairs traded from amongst large random sets. Applications of this approach may include searching for traded pairs, inference of dominant trading strategies, day-by-day investigations of merger arbitrage, and studies of rollovers in futures and options.
