About the webinar:

Financial markets are becoming increasingly efficient at incorporating news information into security market prices.

For scheduled economic news releases the latencies of market reactions are on the order of milliseconds and microseconds. Using a record of microsecond, time-stamped tick data from Thomson Reuters Tick History, we take a granular look at the market impact of US economic news surprises on trading and market by price level activity surrounding liquid index futures contracts.

For unscheduled news events, market reactions can be delayed by seconds or minutes. Thomson Reuters News Analytics (TRNA) is a natural language processing system that provides real-time linguistic and sentiment analytics on financial news, and TRNA can be used as an HFT event detection system to identify market moving news events. In this study we use TRNA over US and UK markets to identify news events which were followed by abnormal price returns, volatilities, and trading volumes at the one-second level. In addition, TRNA is expanding to include native Japanese natural language processing capabilities and using these capabilities, we identify Japanese language news events which significantly impacted JP equity markets at the one-second level.

We can also use TRNA to construct market-wide, macro-sentiment indices by aggregating news sentiment scores over broad universes of companies or asset classes.  We present recent research which demonstrates the significant, macro-behavioral influence of market sentiment on the future performance of market anomalies and fundamental style factors over monthly time horizons.
